Bulk anti-CD8 In Vivo Antibody - Low Endotoxin (YTS-169)

Product Benefits:

ichorbio's anti-CD8 In Vivo Antibody - Low Endotoxin (YTS-169) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio's low endotoxin antibodies have half the endotoxin of comparable antibodies from Bio X Cell at less than 1.0 EU/mg. If ichorbio's low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.5EU/mg) at an even higher purity (98% versus 95%). ichorbio offers Amazon vouchers or donations to the NC3Rs for reviews of this product: click here for more information. ichorbio: the best antibodies for in vivo research.






Rat IgG2b



Species Reactivity:



Anti-CD8 In Vivo Antibody - Low Endotoxin (YTS-169) recognizes an epitope on Mouse CD8

Purification Method:

This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Antigen Distribution:

Present on the surface of most thymocytes and a subpopulation of mature T-lymphocytes which include most T suppressor/cytotoxic cells. CD8 participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck.
