Acetylated histone 3 ac h3

Manufactured by Merck Group

Acetylated histone 3 (Ac-H3) is a post-translationally modified form of the histone protein H3. Histones are responsible for the structural organization of DNA within the nucleus of eukaryotic cells. Ac-H3 is characterized by the acetylation of specific lysine residues on the histone H3 protein, which can influence chromatin structure and gene expression.

ChIP Analysis of Liver Histone Modifications

Chromatin immunoprecipitation (ChIP) analysis was performed as described,23 with the following modifications. Before cross‐linking with 1% formaldehyde, livers were homogenized in PBS and cross‐linked with 0.5 M of di(N‐succinimidyl) glutarate for 45 minutes at room temperature. Immunoprecipitation of samples was performed overnight at 4°C with 3 µg of ChREBP (Novus), acetylated histone 4 (Ac‐H4; Millipore), acetylated histone 3 (Ac‐H3; Millipore), HNF4A (Santa Cruz), or normal rabbit immunoglobulin G (IgG) antibody (Santa Cruz). DNA was purified using the PCR Clean‐up Extraction Kit (Macherey‐Nagel), after which qPCR was performed. Primers are listed in Supporting Table S7.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
