| Name | Human Mast Cell Line (LADR) ; Capable of histamine release (degranulation) |
| Description |
LADR cells were derived from CD34⁺ progenitor cells obtained via bone marrow aspiration from a patient with aggressive mastocytosis, despite the absence of identifiable KIT mutations. LADR cells exhibited log-fold increases in FcεRI/CD117 expression and expressed CD13, CD33, CD34, CD63, CD117, CD123, CD133, CD184, CD193, and CD195. In contrast, previously established LAD2 cells expressed CD33, CD34, CD63, CD117, CD133, and CD193 but lacked CD13, CD123, CD184, and CD195. Morphologically, LADR cells were larger and more granulated, as observed through Wright–Giemsa staining and flow cytometry. Their doubling time was approximately 4 weeks, significantly slower than LAD2 cells, which doubled every 2 weeks. Thus, LADR cells represent a distinct mast cell subline with slower proliferation, more advanced differentiation, increased FcεRI/CD117 and tryptase expression, and a unique gene expression profile, making them a valuable model for studying mast cell development and mastocytosis. |

| Growth Conditions |
PriCoat™ T25 Flasks (G299) are recommended for optimal cell culture. PriGrow X Series Medium for T8156 (TM8156) + 100ng/ml human Stem Cell Factor (Z100815) + 2mM L-Glutamine (G275) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. Note: Thaw cells in a T25; remove debris during the first week post-thaw by skimming, where possible. It is normal to observe cell death in the first two-three weeks after thawing. Allow cells to recover under the recommended culture conditons. Replace half of the medium with an equal volume of fresh medium, weekly. Cells are slow-growing and extremely sensitive to mycoplasma contamination; routine testing should be performed. Do not allow cells to become over-confluent or grow past a density of 1x106 cells/ml. *Cells may lose functionality as a result of continous culture. Degranulation assays must be conducted every 2 months to test functionality -protocol can be found under the "Documents" tab. |
| Unpacking and Storage Instructions |
1. Visually examine the packaging containers for signs of leakage or breakage. 2. Immediately transfer frozen cells from dry ice packaging to a temperature below -130°C, preferably in liquid nitrogen vapor phase storage, until ready for use. To ensure the highest level of viability, thaw the vial and initiate culture as soon as possible upon receipt. If continued storage is desired, the vial should only be stored below -130°C or in liquid nitrogen vapor phase. Do not store at -70°C, as it will result in loss of viability.
|
| Thawing Protocol |
1. Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination. 2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions. 3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 850rpm for 5 minutes. 4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask. 5. Incubate the cells at the recommended conditions. Post-thaw viability should be 70-95% in the first 24 hours. However, this is expected to decrease over the next 2-3 weeks as LADR cells are sensitive to post-thaw conditions and undergo significant death. 6. Debris is expected and should be removed during the first week post-thaw by skimming, where possible. Hemidepletion of media should be performed weekly. Do not perform a complete media change. Allow cells to recover. |
| Subculture Protocol |
1. Transfer expanding cultures to T75 or larger culture vessels to keep cell densities between 5x105 -1x106 cells/ml. Do not exceed 1x106 cells/ml. 2. Remove half the volume of the culture media and replace with fresh media (hemidepletion) the first or second week after thawing. Remove debris by skimming media, if possible. It is normal to see increased cell death for the first 2-3 weeks following thawing. 3. Alternatively, collect cells and centrifuge (750-850 rpm for 5 min) to form a pellet. Discard half the supernatant and re-suspend the cell pellet in the remaining media. Add fresh complete media at a 1:1 ratio and aliquot the cell suspension to new culture vessels, as desired. 4. Incubate the cells at the recommended conditions. Allow cells to recover and perform hemi-depletions with fresh growth media, weekly. |
| Cryopreservation |
Following centrifugation, leave a small amount of culturing media (50-100 uL) and add non-DMSO, non-FBS containing CryoScarless Cryopreservative (BioVerde) at a final concentration of 5x106 cells/mL. Place vials in a cryo container and store at -80°C or in liquid nitrogen for longer preservation. |
| Seeding Density (cells/ml) | 500,000-1,000,000 |
| Population Doubling Time (h) | Initially grow slowly; 4 weeks doubling time |
| Expression |
FcεRI, CD13, CD33, CD34, CD63, CD117, CD123, CD133, CD184, CD193, CD195 |

Print/Download Datasheet
| I want to make sure these cells express my gene of interest before I decide to buy the cell line. Can you provide a sample so this can be tested? | |
|
We do not perform extensive downstream characterization, or gene expression profiling of our cell lines. However, you can check the ‘References’ tab to see if a publication is available, or you can contact us to see if RNA or cell lysates are available for your cell line of interest. Please directly contact us for further information at quotes@abmgood.com.
|
| Does abm's PriGrow series medium contain antibiotics? | |
|
No, the medium does not contain antibiotics and needs to be supplemented by the end-user as desired.
|
| Do I need to use abm's media and Applied Cell Extracellular Matrix (G422) to culture my cells? | |
|
We strongly encourage using the recommended media and culture conditions described in the "Growth Conditions" section as they have been optimized for cell growth. Other supplier's media and coating conditions have not been tested.
|
| What is the difference between Applied Cell Extracellular Matrix (G422) and Collagen Coating? | |
|
The main component of our Applied Cell Extracellular Matrix (G422) is type I collagen specifically. For more information on abm's Applied Cell Extracellular Matrix please visit: http://www.abmgood.com/Applied-Cell-Extracellular-Matrix-G422.html.
|
| Do I have to use T25 ECM-coated flasks for growing the cells? | |
|
We strongly recommend thawing cells in the T25 flasks specified on the cell-specific product page to ensure optimal post-thaw recovery of the frozen cells before testing other culture vessels.
|
| If I want to plate these cells to multi-well plates (e.g. 96 well plates) or dishes, how should I prepare the plates? | |
| What percentage of Trypsin-EDTA should be used to subculture cells? Can I use Trypsin-EDTA containing phenol red? | |
|
The standard concentration used for subculturing is 0.25% Trypsin-EDTA, available at abm (Cat. No. TM050). Yes, Trypsin-EDTA containing phenol red can be used as it does not interfere with trypsinization.
|
| How often do I need to change the media? | |
|
Media should be changed every 2-3 days or as specified within the recommended growth conditions.
|
| Why are these cells classified as biosafety level II? | |
|
We follow the CDC-NIH recommendations that all mammalian sourced products should be handled at the Biological Safety Level 2 to minimize exposure of potentially infectious products. This information can be found in 'Biosafety in Microbiological and Biomedical Laboratories' (1999). Your institution's Safety Officer or Technical Services will be able to make the call as to whether BioSafety Level I is possible with these cells at your site, if desired.
|
| How long can I store frozen vials? | |
|
Cells that are properly frozen using an effective cryoprotective agent can be stored in liquid nitrogen vapor phase (or below -130°C) indefinitely without affecting viability.
|
| What is the recommended storage temperature for cells? | |
|
In general, if you received:
|
| Can I substitute heat-inactivated FBS with FBS or vice versa? | |
|
FBS and heat-inactivated FBS are different in their composition; they cannot be substituted for one another.
|
| My cells are not detaching, what method do you recommend to trypsinize the cells? | |
|
| How are live cells shipped? | |
|
Live cells are shipped as a live culture in a T12.5 flask. Cells are seeded at an optimal confluency to avoid metabolic waste build up during transport. In addition, we thoroughly test our cell lines for functional freeze-thaw recovery. For more information on how to handle live cells, please view our detailed instructions here (https://www.abmgood.com/uploads/document/Cell_Handling_Instructions_Upon_Arrival_150623.pdf).
|
| Why are cells not attaching and forming clumps after subculturing with trypsin? | |
|
Cells form clumps and display attachment issues when the trypsinization agent is not effectively neutralized. To completely neutralize the trypsin agent, add an equal amount of complete growth media prior to centrifugation. Subtle changes in culture conditions, particularly in pH and the quality of serum used in the growth medium, may also affect the amount of clumping exhibited by the cells.
|
| Why are my cells forming clumps after plating? | |
|
It is important to ensure cell clumps are broken up through gentle re-suspension by pipetting up and down several times after pelleting cells by centrifugation. This will ensure a homogenous single cell suspension for even plating.
|
| Do I need to add the selection drug to the complete growth medium? | |
|
We recommend maintaining selection pressure using the drug concentration specified in the Growth Conditions section.
|
| Where can I find the CoA for my product? | |
|
