Bulk anti-CD28 In Vivo Antibody – Low Endotoxin (37.51)
ichorbio’s anti-CD28 In Vivo Antibody – Low Endotoxin (37.51) 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 our competitors 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 (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.
ichorbio’s 37.51 in vivo antibody is available in the following bulk sizes:
1mg, 5mg, 25mg, 50mg and 100mg
ichorbio regularly manufactures multi-gram amounts of our anti-CD28 37.51 clone – please contact us for pricing.
Syrian Hamster IgG
Anti-CD28 In Vivo Antibody – Low Endotoxin (37.51) recognizes the CD28 co-stimulatory receptor, a ligand of CD80 (B7-1) and CD86 (B7-2). CD28 is important for transmitting co-stimulatory signals for optimal T-cell activation.
Anti-CD28 is present on most thymocytes, CD4+, CD8+ T-cells. The 37.51 antibody augments proliferation and IL-2 production by activated T-cells. Clone 37.51 antibody has been shown to stimulate the proliferation and cytokine production by activated T and NK cells and provide a costimulatory signal for CTL induction.
