Bioorthogonal chemistry provides one of the possibilities to modify various biomolecules in their native environment. The combination of Click chemistry with the BONCAT method (bioorthogonal non-canonical amino acid tagging) is widely used for tagging and analysis of newly synthesized proteins, which are clearly distinguishable from the pre-existing protein pool. However, the commonly used procedure results in low quality 2D electrophoretic profiles. We put a lot of effort into obtaining clear results using a standard Click protocol, with a negligible effect. Here we describe a Click-on-membrane approach which we successfully used not only to monitor de novo protein synthesis but also to detect newly synthesized RNA.
