Anti-HSP40-4 Antibody

Supplied by Antibodies.com, this affinity-purified polyclonal reagent is raised in rabbit against HSP40-4 (DnaJ homolog subfamily A member 1) and is designed to detect endogenous levels of the target protein across human, mouse, and rat samples. The antibody is provided as a 50 µl liquid formulation in PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide at a working concentration of 1 mg/mL, and is unconjugated for maximum flexibility in downstream assay design. It was generated using a synthesized peptide derived from the internal region of human HSP40-4, then affinity-purified from rabbit antiserum by epitope-specific affinity chromatography, ensuring selective recognition of the immunogen. Validated applications include Western blot (WB) and ELISA, making the reagent suitable for routine detection and semi-quantitative work in cell and tissue lysates, as illustrated by the provider's Western blot data on mouse liver, kidney, and brain samples. The product is shipped at 4 °C; upon arrival it should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve antibody activity. Host species is rabbit, clonality is polyclonal, and the conjugate state is unconjugated, leaving the user free to choose secondary labels or enzymatic systems. The 50 µl pack size offers a practical volume for multiple blotting or plate-based experiments while maintaining the lot-to-lot consistency expected of a polyclonal preparation. As with all research-grade reagents from Antibodies.com, this antibody is intended for research use only and is not validated for diagnostic or therapeutic applications.
