Tag(s): C-terminal Fc fusion (Human IgG1), C-terminal Avi-tag™
a.a: 35-242

Human secreted B7-1-Fc fusion protein, also known as CD80, with C-terminal Avi-tag™. GenBank Accession No. NM_005191, a.a 35-242 expressed in a HEK293 cell expression system and enzymatically biotin-labeled using Avi-tag™ technology. MW = 52.5 kDa (monomer). This protein runs at a higher M.W. by SDS-PAGE due to glycosylation.

CTLA-4 Counter-Receptor B7.1
Assay Conditions:
Reaction done according to CTLA4:B7-1[biotin] assay kit (Catalog # 72009) protocol. Buffer is PBS + 0.1% BSA. Blocking buffer is Superblock + 0.05% Tween-20. Coat protein was added ON at 4 deg 100 ng/well. Various concentrations of biotinylated ligand (0-8ng/ul, 0.5 ng/ul is the recommended kit condition) added for 2h at RT. Strep-HRP added for 1h at RT.
40 mM Tris, pH 8.0, 110 mM NaCl, 2.2 mM KCl, and 20% glycerol.
Aqueous buffer solution
Storage / Stability:
At least 6 months at –80°C.
Useful for the study of protein-protein interaction and in vitro and in vivo protein function studies.
