Description

Binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA-3') that can act as a lymphoid-specific enhancer. This protein is a transcriptional activator that may be specifically involved in the differentiation or activation of macrophages or B-cells. Also binds RNA and may modulate pre-mRNA splicing (By similarity). [UniProt]

Application Notes

The stated application concentrations are suggested starting points. Titration of the PU.1 antibody may be required due to differences in protocols and secondary/substrate sensitivity.

Immunogen

A portion of amino acids 16-170 from the human protein was used as the immunogen for the PU.1 antibody.

Storage

Store the PU.1 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
