Anti-CRBP II Antibody

CRBP II (Cellular Retinol-Binding Protein II) is an intestinal cytosolic carrier protein critical for vitamin A uptake, intracellular transport, and esterification in small intestine enterocytes. This polyclonal reagent from Antibodies.com is raised in rabbit and supplied unconjugated at 100 µl per vial, validated for Western blot and ELISA workflows against human, mouse, and rat samples. Investigators apply it to map retinol trafficking across intestinal villus absorptive cells and hepatic tissue, complementing studies of dietary vitamin A absorption and hepatic stellate cell biology. The antibody recognizes the endogenous CRBP II protein without fluorescent or enzymatic labeling, integrating cleanly into standard immunodetection protocols including chemiluminescent Western blot on whole-cell lysates and indirect ELISA on recombinant antigen. Polyclonal reactivity to multiple epitopes supports robust signal across denatured and native preparations, while the unconjugated format leaves reporter choice to the end user for chromogenic, fluorescent, or HRP-based readouts.
