Product Description

Source: Recombinant protein corresponding to aa35-242 from human B7-1, fused at the C-terminus to the Fc portion of human IgG1 and with a C-terminal Avi-Tag, expressed in HEK293 cells. Molecular Weight: ~53kD Assay Conditions: Reaction done according to CTLA4:B7-1[biotin] BioAssay(TM) kit protocol. Buffer is PBS + 0.1% BSA. Blocking buffer is Superblock + 0.05% Tween-20. Coat protein was added ON at 4 deg 100ng/well. Various concentrations of biotinylated ligand (0-8ng/ul, 0.5ng/ul is the recommended kit condition) added for 2h at RT. Strep-HRP added for 1h at RT. Applications: Suitable for use in the study of protein-protein interaction and in vitro and in vivo protein function studies. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: Aliquot to avoid repeated freezing and thawing and store at -70C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
