Applications
It expresses surface HLA B7 but does not secrete HLA B7.
C1R-B7 is a stable transfectant cell line established in 1988 with a normal major histocompatibility complex (MHC) HLA B7 gene.
B-LCL by gamma irradiation followed by selection for Class I monoclonal antibodies and complement.
C1R is a human B-cell lymphoblastoid line lacking surface HLA A and B antigens.
C1R was derived from Hmy.
C1R-B7 may be used as a control for C1R-sB7; in CTL experiments and for producing control supernatants.
