Background

TH2B (testis-specific H2B) is originally identified as a testis-specific variant of histone H2B. TH2A is a testis-specific variant of histone H2A. They are abundant in the testis, oocytes and fertilized eggs. TH2A and TH2B are controlled by a shared promoter that is located between them. Disruption of Th2a and Th2b genes causes defects in spermatogenesis. TH2A/TH2B may enhance reprogramming by introducing processes that normally operate in zygotes and during SCNT. TH2A and TH2B induce nucleosome instability. TH2B controls the chromatin-to-nucleoprotamine transition.

Application Notes

Recombinant histone TH2B is suitable for use as substrate for histone modification enzymes, or to generate chromatin in vitro.

Protein Details

Recombinant Histone TH2B (assession number: NP_733759.1) was expressed in E. coli cells as full length protein without any tag. The molecular weight of TH2B is about 14.2 kDa. The recombinant histone is >95% pure by SDS-PAGE.

Storage

Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.
