Organism Rattus norvegicus (B cell); Mus musculus (myeloma), rat (B cell); mouse (myeloma)
Cell Type hybridoma: B lymphocyte
Morphology lymphoblast
Culture Properties suspension
Biosafety Level 1

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Applications
The antibody reacts with the B7-2 (GL1) antigen present on activated mouse B cells.
B7-2 shows minimal expression on unstimulated B cells, but is expressed at high density on activated B cells.
Derivation
Spleen cells were fused with Sp2/0-Ag14 myeloma cells.
Genes Expressed
immunoglobulin; monoclonal antibody; against mouse B7-2 antigen
Cellular Products
immunoglobulin; monoclonal antibody; against mouse B7-2 antigen
Comments
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).
