Chromatin immunoprecipitation (ChIP) optimization

WebChromatin immunoprecipitation, or ChIP, is an antibody-based technology used to selectively enrich specific DNA-binding proteins along with their DNA targets. ChIP is used to investigate a particular protein-DNA interaction, several protein-DNA interactions, or interactions across the whole genome or a subset of genes. WebN-ChIP is suitable for targets such as histones and histone modifications. However, it is important to note that, without additional cross-linking, in vivo modifications in nucleosomes may still occur during your analysis. When targeting proteins that bind weakly to DNA, we highly recommend a crosslinking ChIP (X-ChIP) protocol. can hand sanitizer be checked in luggage
