Background:
Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.
VALIDATION IMAGES
To determine the titer, an ELISA was performed using a serial dilution of the H3K23ac antibody (bs-53076R). The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1:2,750.
A Dot Blot analysis was performed to test the cross reactivity of the H3K23ac antibody (bs-53076R) with with peptides containing other modifications and unmodified sequences of histone H3. One hundred to 0.2 pmol of the peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:1,000. The figure shows a high specificity of the antibody for the modification of interest.
