HIST3H2A Protein, Human

The HIST3H2A protein is a core component of nucleosomes that compact DNA into chromatin. HIST3H2A Protein, Human is the recombinant human-derived HIST3H2A protein, expressed by E. coli , with tag free.

HIST3H2A, as a core component of the nucleosome, participates in the essential process of wrapping and compacting DNA into chromatin, thereby limiting DNA accessibility to cellular machineries that rely on DNA as a template. This histone protein, like others, holds a pivotal position in key cellular functions such as transcription regulation, DNA repair, DNA replication, and the maintenance of chromosomal stability. The intricate control of DNA accessibility involves a sophisticated system of post-translational modifications known as the histone code, along with dynamic nucleosome remodeling. The nucleosome itself is a histone octamer comprising two molecules each of H2A, H2B, H3, and H4, assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. This octamer efficiently wraps approximately 147 base pairs of DNA, underscoring its crucial role in organizing chromatin structure and facilitating essential genomic processes.

15-20 kDa.

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
