Background
Histone H3 is a critical component of the nucleosome, which is the basic unit of chromatin. It plays a vital role in the regulation of gene transcription and is subject to various post-translational modifications (PTMs) that affect chromatin structure and gene expression. The H3 family includes several variants, with H3.1, H3.2, and H3.3 being the most well-known. H3.1 and H3.2 are deposited during DNA replication, while H3.3 can be deposited independently of DNA replication and is incorporated throughout the cell cycle2. Post-translational modifications of Histone H3, particularly on the N- and C-terminal tails, can influence the interaction between histones and DNA, as well as with other chromatin factors. These modifications can either promote a relaxed chromatin state that allows gene transcription or lead to a condensed chromatin state that typically suppresses transcription.

ChIP

Chromatin immunoprecipitation (ChIP) was performed on HeLa cells cross - linked with 1% formaldehyde for 10 min, then chromatin was fragmented by sonication. Parallel reactions used Histone H3 Recombinant Rabbit mAb (SDT-266-44) and Rabbit mAb IgG Isotype Control (SDT-R173) at 1:50 for immunoprecipitation. Post - immunoprecipitation, both samples were washed, eluted, and cross - links reversed. Purified DNA was analyzed by qPCR.
qPCR (%input: immunoprecipitated DNA/input DNA) showed the enrichment of RPL30, GAPDH, MYOD1, AFM, SAT-α and SAT-2 in Histone H3 Recombinant Rabbit mAb (SDT-266-44)-immunoprecipitated sample.
