Anti-ALDH1A1 Antibody

This recombinant rabbit monoclonal antibody targets ALDH1A1 (Aldehyde Dehydrogenase 1 Family Member A1), a cytosolic enzyme that catalyzes the oxidation of retinaldehyde to retinoic acid and is widely used as a marker of cancer stem cells and normal progenitor populations. Provided by Antibodies.com as a primary antibody in unconjugated format, the reagent is validated for Western blot (WB) and immunohistochemistry (IHC) workflows and shows reactivity with Human, Mouse, and Rat samples, supporting cross-species studies in tumor biology, retinoid signaling, and alcohol-metabolism research.

The antibody is supplied as 100 µL of recombinant rabbit monoclonal antibody in 1×TBS (pH 7.4) with 1% BSA, 40% glycerol, and 0.05% sodium azide as preservative — a glycerol-containing buffer formulation that allows frozen aliquoting and protects antibody activity through repeated freeze-thaw cycles. Researchers apply this reagent to identify ALDH1A1-expressing cell populations in tissue sections, to probe retinoic acid biosynthesis pathways, and to investigate stem-like tumor cell phenotypes linked to chemoresistance in carcinomas of the breast, lung, and colon.
