Our professional protein sequencing platform provides N-terminal sequence analysis by Edman degradation or mass spectrometry (MS), with complementary advantages to each other.
De novo sequencing is an appropriate method for identifying novel peptides, unsequenced organisms, and antibodies drugs, which can't be detected by database search methods.
iTRAQ, using isobaric reagents to label peptides, is ideally suited for comparing normal, diseased, and drug-treated samples, time course studies, biological replicates and provides relative quantitation information.
Short-chain fatty acids (SCFAs) are the end products of fermentation of the dietary fibers by large intestinal bacteria. We have established sensitive, reliable, and accurate GC-MS methods for quantification of short-chain fatty acids
Bile acids, a large family of steroids, have a carboxyl group in the side chain. We have developed a sensitive and rapid method for the analysis of the 66 bile acids samples by LC-MS.
