Heat shock transcription factor 2 is a protein that binds specifically to the heat-shock element and has homology to HSFs of other species. Mouse HSF2 was expressed in all three embryonic layers at embryonic day 7.5 and the head fold was strongly stained at embryonic day 8.5. In adults, expression is detected in spermatocytes and spermatogonia, but not in elongated spermatids, spermatozoa, or Sertoli cells. It mediates Hsp70i bookmarking, binding to this promoter in mitotic cells, recruits protein phosphatase-2A, and interacts with the CAPG subunit of the condensin enzyme to promote efficient dephosphorylation and inactivation of condensin complexes in the vicinity, thereby preventing compaction at this site. And HSF2-null mice were born at the expected mendelian ratio but had brain abnormalities and meiotic and gametogenic defects in both genders.

Application Notes

The stated application concentrations are suggested starting amounts. Titration of the HSF2 antibody may be required due to differences in protocols and secondary/substrate sensitivity.


An amino acid sequence from the middle region of human HSF2 (KQERDGPVEFQHPYFKQGQDD) was used as the immunogen for this HSF2 antibody.


After reconstitution, the HSF2 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
