Mfr No 305126
Species Human
The HMy2.CIR cell line was developed through gamma irradiation and subsequent selection for the loss of HLA class I antigen expression from the HMy.2 B lymphoblastoid cell line. This parental cell line is a fast-growing mutant derived from the ARH-77 cell line. HMy2.CIR cells are particularly valuable as hosts for transfected class I major histocompatibility antigen genes, offering a versatile platform for studying antigen presentation and immune response mechanisms. The ARH-77 cell line, from which HMy2.CIR is ultimately derived, is known to be positive for Epstein-Barr nuclear antigen (EBNA+) and Epstein-Barr viral capsid antigen (EBVCA+). Consequently, the HMy2.CIR cell line is also presumed to be EBNA positive. This cell line is characterized by its expression of small amounts of HLA Cw4, but it does not express HLA A or B locus products. This unique antigen expression profile makes HMy2.CIR cells a useful model for immunological research, particularly in the study of HLA class I-restricted antigen processing and presentation.

  • cultureMedium: IMDM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 25 mM HEPES, w: 1.0 mM Sodium pyruvate, w: 3.024 g/L NaHCO3 (Cytion article number 820800a)
  • 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 105 cells/ml with fresh culture medium, and aliquot the adjusted suspension into new flasks for further cultivation.
  • fluidRenewal: 2 to 3 times per week
  • freezeMedium: As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
