N-terminal Sequencing (also called Edman sequencing) uses a chemical process based on the technique developed by Pehr Edman in the 1950's. N-terminal sequencing is a method to excise amino acid one by one from N-terminal of protein or peptide to be segregated by HPLC (reversed phase HPLC), then to detect by UV to determine amino acid sequence by the time the peak is gained (Chromatogram). Pure proteins (>90%) usually generate easily interpreted data, but insufficiently purified protein mixtures may also provide useful data. Long sequences of 50 amino acids or more are possible with this technique.
Discovery and validation of protein and peptide biomarkers in clinical proteomics requires large numbers of patient samples. Traditional methods are complicated, time-consuming and lack standardization. Peptide profiling with magnetic chromatography beads offers quick, reproducible screening and can be automated to run 96 samples in a day from start to finish. The method is reproducible and can be standardized, facilitating clinical and inter-laboratory collaborations.

This service is a quantitative and qualitative analysis of two or more complex samples such as cell lysates, tissue homogenates or biofluids. The results from this experiment provide a catalogue of the proteins present in all samples and a statistical analysis reflecting the changes in the protein levels observed across the samples, along with associated pathway information.
PTMs(hereafter): Phosphorylation (pS/T, pY), Methylation, Deamidation, Oxidation, Nitration, N-glycosylation, Amino acid mutation, Unnatural amino acid, Chemical modifications, Palmitoylation, Glycosylation, Ubiquitination, SUMOylation, Dimethylation, Acetylation, Decarboxylation, etc..
De Novo Peptide Sequencing is a tech to analyze proteins or peptides not present in currently available databases. We use tandem mass spectrometry (MALDI TOF-TOF, or electrospray MS/MS) to determine the primary sequence structure. The expert operators will then use the PEAKS Software to interpret the MS/MS spectra and derive the customer sequence.
