Bulk anti-4-1BB In Vivo Antibody - Low Endotoxin (3H3)

Bio X Cell:
ICH1036 is up to 30% cheaper for academia & non-profits and up to 55% cheaper for industry than the equivalent product from Bio X Cell (BE0239). Product Benefits:

ichorbio's anti-4-1BB In Vivo Antibody - Low Endotoxin (3H3) 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 3H3 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-4-1BB 3H3 clone - please contact us for pricing.

4-1BB ligand receptor, T-cell antigen 4-1BB, Tnfrsf9, Ila, Ly63, CD137





Species Reactivity:

Mouse, Rat


Anti-4-1BB In Vivo Antibody - Low Endotoxin (3H3) recognizes an epitope on Mouse 4-1BB

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:

Activated T cells and B cells


4-1BB (CD137) is a costimulatory molecule expressed on the surface of activated T cells and plays a role in T-cell-mediated proliferative response. 4-1BB signal regulates CD28 co-stimulation in the targeted subset cells to favor Th1 development and maintain long-term cell growth. 4-1BB is also expressed on dendritic cells (DCs) and controls the duration, DC-T interaction, and, therefore, immunogenicity. Clone 3H3 antibody is an agonistic antibody that has been shown to stimulate 4-1BB signaling in vivo.
