Bulk anti-LAG-3 In Vivo Antibody - Low Endotoxin (C9B7W)

Bio X Cell:

ICH1078 is up to 37% cheaper for industry than the equivalent low endotoxin version from Bio X Cell (BE0174). ICH1078UL (ultra-low endotoxin) is up to 36% cheaper for industry than the same format from Bio X Cell (BP0174).

Product Benefits:

ichorbio's anti-LAG-3 In Vivo Antibody - Low Endotoxin (C9B7W) 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: the best antibodies for in vivo research.






ichorbio's C9B7W 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-LAG-3 C9B7W clone - please contact us for pricing.


Rat IgG1

Other Names:

Lymphocyte activation gene 3 protein, Aida, CD223





Species Reactivity:

Mouse, Rat


Anti-LAG-3 In Vivo Antibody - Low Endotoxin (C9B7W) recognizes an epitope on Mouse LAG-3

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:

T-cells and NK cells


LAG-3, also known as CD223, is 70 kD type I transmembrane glycoprotein within the Ig superfamily. CD223, like CD4, binds MHC class II molecules, but with higher affinity than CD4. Clone C9B7W antibody has been reported to block the function of murine LAG-3 in vivo and in vitro.
