Medchemexpress LLC Amt-nhs | 2925268-86-4 | 98.7% | 443.47 | 100 MG
AMT-NHS is an RNA-protein crosslinker composed of a psoralen derivative and an N-hydroxysuccinimide ester group. It reacts with RNA bases and primary amines of protein, respectively. It can penetrate into living yeast cells to crosslink Cbf5 to H/ACA snoRNAs with high specificity, inducing different crosslinking patterns and targeting both single- and double-stranded regions of RNA. It is used for capturing diverse RNA-protein interactions in cells.
