Permits and Restrictions

View Permits

Organism Homo sapiens, human
Cell Type B lymphoblast
Product Format frozen
Morphology lymphoblast
Culture Properties suspension
Biosafety Level 2 [Cells contain Eptein-Barr Viral DNA sequences]
Applications The cells are useful as host for transfected class I major histocompatibility antigen genes.
Storage Conditions liquid nitrogen vapor phase
Derivation
The HMy2.CIR cell line was derived from the HMy.2 B lymphoblastoid cell line, a fast growing mutant of the ARH-77 cell line (ATCC CRL-1621), by gamma irradiation and selection for loss of HLA class I antigen expression.
Comments

The CRL-1621cell line is reported to be positive for Epstein-Barr nuclear antigen (EBNA +) and Epstein-Barr viral capsid antigen (EBVCA +). 

Since the HMy2.CIR cell line was derived from the HMy.2 B lymphoblastoid cell line, a fast growing mutant of the ARH-77 cell line (ATCC CRL-1621), it is assumed to be EBNA positive.

The cells express no HLA A or B locus products, but do express small amounts of HLA Cw4.


Complete Growth Medium The base medium for this cell line is ATCC-formulated Iscove's Modified Dulbecco's Medium, Catalog No. 30-2005. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
