Comments: GL1細(xì)胞Animals were immunized with LPS activated DBA/2J mouse B cells.
Spleen cells were fused with Sp2/0-Ag14 myeloma cells.
The antibody reacts with the B7-2 (GL1) antigen present on activated mouse B cells.
The B7-2 antigen is a ligand for CTLA-4 (T cell activation molecule).
B7-2 shows minimal expression on unstimulated B cells, but is expressed at high density on activated B cells.
It is distinct from B7-1 (previously referred to as B7).
Propagation: ATCC complete growth medium: RPMI 1640 medium with 1% nonessential amino acids and 0.05 mM 2-mercaptoethanol, 90%; fetal bovine serum, 10%
Subculturing: Medium Renewal: Every 2 to 3 days
GL1細(xì)胞Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 2 X 10 exp5 cells/ml and maintain between 1 X 10 exp5 and 1 X 10 exp6 cells/ml.
Preservation: Culture medium, 95%; DMSO, 5%
