Anti-HSP40-4 Antibody

Targeting the HSP40-4 J-domain co-chaperone that works alongside Hsp70 during protein folding and cellular stress responses, this polyclonal reagent from Antibodies.com is raised in rabbit and supplied as 100 µl of unconjugated antiserum. The antibody is validated for Western blot and ELISA workflows and shows reactivity with Human, Mouse, and Rat samples, supporting comparative work across standard laboratory model systems and human-derived material. Because the polyclonal format recognizes multiple epitopes on the endogenous HSP40-4 target, it is well suited to immunoblot detection of stress-induced expression changes following heat shock, oxidative challenge, or other proteotoxic insults where J-protein co-chaperones are typically upregulated.
