Bulk anti-TNF alpha In Vivo Antibody - Low Endotoxin (TN3-19.12)

Bio X Cell:
ICH1136 is up to 37% cheaper for industry than the equivalent product BE0244 from Bio X Cell. Product Benefits:

ichorbio's anti-TNF alpha In Vivo Antibody - Low Endotoxin (TN3-19.12) is manufactured in a cGMP compliant 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: the best antibodies for in vivo research.


TNF alpha




ichorbio's TN3-19.12 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-TNF alpha TN3-19.12 clone - please contact us for pricing.

The tumor necrosis factor (TNF-alpha) is a multifaceted polypeptide cytokine known as a mediator of inflammation and immunity. It may mediate some of the significant changes in cellular homeostasis which accompany the invasion of the mammalian host by viruses, bacteria, and parasites. TNF-alpha is an acute phase protein which initiates a cascade of cytokines and increases vascular permeability, thereby recruiting macrophage and neutrophils to a site of infection. TNF-alpha secreted by the macrophage causes blood clotting which serves to contain the infection. TNF-alpha has been detected in synovial fluid of patients with rheumatoid arthritis. Clone TN3-19.12 antibody can neutralize the bioactivity of natural or recombinant TNF-alpha

How much TN3-19.12 to use in vivo:

We recommend using 250 µg per mouse when performing in vivo; research using ichorbio’s low endotoxin TNF alpha antibody clone TN3-19.12. This range is based off the most recent publication data using the TN3-19.12 clone in vivo. Each investigator should determine their own optimal working dilution for specific applications.
