Anti-Rat Kappa Light Chain In Vivo Antibody (MAR 18.5) - Low Endotoxin

Product Benefits:

ichorbio's anti-Rat Kappa Light Chain In Vivo Antibody (MAR 18.5) - Low Endotoxin 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 (<0.5 EU/mg) at an even higher purity (98% versus 95%).

ichorbio: the best antibodies for in vivo research.


Kappa Light Chain


MAR 18.5


ichorbio's MAR 18.5 in vivo antibody is available in the following bulk sizes: 5mg, 25mg, 50mg and 100mg. ichorbio regularly manufactures multi-gram amounts of our anti-Rat Kappa Light Chain MAR 18.5 clone - please contact us for pricing.


Mouse IgG2a kappa



Species Reactivity:



MAR 18.5 activity is directed against rat kappa immunoglobulin light chain of both RI-1a and RI-1b allotypes.

Antigen Distribution:

Immunoglobulins consist of heavy chains and light chains. Kappa is a class of light chain and is encoded by the V (variable), J (joining), and C (constant) segments.


Soluble rat immunoglobulin.
