Anti-KRAS Antibody

Offered through Antibodies.com, this affinity-purified polyclonal reagent is raised in rabbit against a recombinant human KRAS immunogen and is supplied at 1.0 mg/mL in a 50 µL volume of phosphate-buffered saline (pH 7.4) containing 150 mM NaCl, 0.02% sodium azide and 50% glycerol. The unconjugated IgG preparation is validated for Western blotting at a working dilution of 1:200–1:500 and for immunohistochemistry at 1:50–1:100, and it recognises endogenous levels of total KRAS protein in human, mouse and rat samples, making it a flexible choice for cross-species signalling studies. Recommended storage is at –20 °C, and the buffer formulation is consistent with standard freeze–thaw handling of polyclonal IgG reagents. Each lot is purified by affinity chromatography on the immunogen to reduce background, supporting clean detection of the low-molecular-weight GTPase in lysates and tissue sections. The product ships from St. Louis, Missouri with a typical lead time of six to nine business days and is intended for research use only, not for diagnostic or therapeutic applications.
