Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Pdx1 Antibody detects endogenous levels of total Pdx1 protein.

Species predicted to react based on 100% sequence homology: Human

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human Pdx1. Antibodies are purified by protein A and peptide affinity chromatography.

The pancreatic duodenal homeobox gene-1 (Pdx1) is a transcription factor that contributes to pancreas development, pancreatic β-cell differentiation, and mature β-cell function (1,2). It plays an essential role in the commitment of endoderm to a pancreatic and later β-cell phenotype (2,3). In the mature pancreas, Pdx1 expression is more restricted to the pancreatic β-cells (3), where it promotes the expression of genes important for β-cell functions such as insulin, glucokinase, and Glut2 (4-6). Mutations of the corresponding Pdx1 gene may be associated with diabetes and cases of pancreatic insufficiency (7).
