Anti-HSP40 Antibody

Raised in rabbit against HSP40 (also called DNAJB1), this polyclonal primary antibody from Antibodies.com supports studies of heat-shock and co-chaperone biology across human, mouse, and rat samples. HSP40 belongs to the DNAJ family and drives ATP hydrolysis by Hsp70, so the reagent fits work on protein-folding stress, chaperone-assisted refolding, and misfolded-protein clearance pathways.

The unconjugated Ig fraction is supplied as a 100 µl vial at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, a cryoprotective mixture that tolerates routine freeze-thaw handling. The buffer is intended for laboratory research use only, not for diagnostic or therapeutic work; keeping the parent vial frozen in working aliquots helps preserve activity over the aliquot's typical use window.

Validated applications are Western blot on cell and tissue lysate, immunohistochemistry on fixed sections, and immunofluorescence on cultured cells, providing both expression-level readouts by WB and spatial localization by IHC and IF in chaperone, neurodegeneration, and cancer research programs.
