Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation, F=Flow Cytometry, IF-IC=Immunofluorescence (Immunocytochemistry),

Specificity / Sensitivity

ALDH1A1 (D9J7R) XP® Rabbit mAb recognizes endogenous levels of total ALDH1A1 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human ALDH1A1 protein.



Confocal immunofluorescent analysis of A549 (positive, left) and HeLa (negative, right) cells using ALDH1A1 (D9J7R) XP® Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using ALDH1A1 (D9J7R) XP® Rabbit mAb.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of HeLa (blue) and ACHN (green) cells using ALDH1A1 (D9J7R) XP® Rabbit mAb. Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4412 was used as a secondary antibody.


The aldehyde dehydrogenase family is a large group of enzymes that oxidize aldehydes formed through metabolic processes to their carboxylic acids (1). ALDH1A1 is a liver cytosolic isoform of acetaldehyde dehydrogenase and is involved in the major pathway of alcohol metabolism along with alcohol dehydrogenase (2). ALDH1A1 is also known as retinal dehydrogenase 1 and is involved in retinol metabolism, converting retinol to retinoic acid (3). Recent studies suggest that control of retinoid signaling through ALDH1A1 may influence hematopoietic stem cell differentiation (4). There has been recent interest in ALDH1 isoforms as predictive biomarkers in disease. Several studies have suggested that ALDH1A1 is a potential marker for cancer stem cells and chemoresistance in several tumor types, such as melanoma (5), lung cancer (6), and glioblastoma (7).
