Pancreas transcription factor 1 subunit alpha is a protein that in humans is encoded by the PTF1A gene. It is mapped to 10p12.2. This gene encodes a protein that is a component of the pancreas transcription factor 1 complex (PTF1) and is known to have a role in mammalian pancreatic development. The protein plays a role in determining whether cells allocated to the pancreatic buds continue towards pancreatic organogenesis or revert back to duodenal fates. The protein is thought to be involved in the maintenance of exocrine pancreas-specific gene expression including elastase 1 and amylase. Mutations in this gene cause cerebellar agenesis and loss of expression is seen in ductal type pancreas cancers.

Optimal dilution of the PTF1A antibody should be determined by the researcher.

Recombinant human protein (amino acids M1-Q292) was used as the immunogen for the PTF1A antibody.

After reconstitution, the PTF1A antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
