Traceless cross-linker for photocleavable bioconjugation.

ABSTRACT: Photoresponsive bioconjugation empowers the development of novel methods for drug discovery, disease diagnosis, and high-throughput screening, among others. In this paper, we report on the characteristics of a traceless photocleavable cross-linker, di-6-(3-succinimidyl carbonyloxymethyl-4-nitro-phenoxy)-hexanoic acid disulfide diethanol ester (SCNE). The traceless feature and the biocompatibility of this photocleavable cross-linking reagent were corroborated. Consequently, we demonstrated its application in reversible phage particle immobilization that could provide a platform for direct single-phage screening. We also applied it in protein-photoprinting, where SCNE acts as a "photo-eraser" to remove the cross-linked protein molecules at a desired region in a simple, clean, and light-contr
