A3 Cells
General information
Description | A3 cells are human T lymphoblasts derived from the Jurkat cell line obtained from the laboratory of Gerald Crabtree at Stanford University. These cells possess a lymphoblast morphology, grow in suspension and are highly relevant in studying acute T cell leukaemia, 3D cell culture applications, immune system disorder research, and immunology. These cells are derived from the Jurkat cell line, which was treated with Fas Antibody to obtain a low spontaneous resistance rate to Fas-mediated apoptosis. This characteristic makes A3 cells highly valuable for investigating immune system dysregulation and identifying potential therapeutic targets. |

Identifiers / Biosafety / Citation
Citation | A3 (Cytion catalog number 305143) |
---|---|
Biosafety level | 1 |
Expression / Mutation
Handling
Culture Medium | RPMI 1640, w: 2.1 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS |
Subculturing | Gently homogenize the cell suspension in the flask by pipetting up and down, then take a representative sample to determine the cell density per ml. Dilute the suspension to achieve a cell concentration of 1 x 10^5 cells/ml with fresh culture medium, and aliquot the adjusted suspension into new flasks for further cultivation. |
Split ratio | 1:2 to 1:4 |
Fluid renewal | 2 to 3 times per week |
Freeze medium | CM-1 (Cytion catalog number 800100) or CM-ACF (Cytion catalog number 806100) |

Quality control / Genetic profile / HLA
Sterility | Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |
