Profile: SBW specializes in providing drug discovery and development for functional food & chemical safety industries. We offer comprehensive services and platforms for drug discovery, functional food ingredients testing, chemical safety assessment and related life science areas. Peptide mass fingerprinting (PMF) is a fastest and cheap method of protein identification. The procedure involves optional protein enrichment followed by excision of the band from the gel. Alternatively protein identification can also be done directly from any protein sample in dissolved form. Multiple reaction monitoring (MRM) assay is considered the most selective and sensitive mass spectrometry technique to detect proteins of interest with enhanced specificity using selective ion monitoring scanning mode. During this process, complex biological protein samples will be enzymatically digested and peptides of specific masses are selected & all others are excluded followed by fragmentation of the selected peptides in MS and quantification of the known daughter ions. LC/MRM (SRM)-MS is a versatile tool for the discovery phase, quantization of proteins during validation phase or post-translational modification profiling in complex biological samples.
