WebbNovel proteomic techniques provide the ability to assay protein expression in samples in a high-throughput manner across the translated human genome. These technologies may enable researchers to identify unique protein expression, or expression patterns, in cancer compared with normal tissues. WebbThe concentration of proteins was quantified using the bicinchoninic acid (BCA) protein assay kit (Thermo Fisher Scientific). Next, 40 µg of total protein from each sample was separated using 10% polyacrylamide gels (Beyotime), which was followed by transfer to polyvinylidene fluoride (PVDF) membranes (Hoffman-La Roche Ltd., Basel, Switzerland).
WebbThis includes epitope mapping, custom labeling and performance testing on multiple platforms. In addition, we offer all services for ELISA assay development, ELISA platform optimization and ELISA assay format modification. Our scientists experienced in all facets of protein expression to aid our clients in designing the best system for their needs. WebbProtein assays differ in their chemical basis for detecting protein-specific functional groups. Some assay methods detect peptide bonds, but no assay does this exclusively.
