APTBIO supplies shotgun proteomics service referring to the use of bottom-up proteomics techniques in identifying proteins in complex mixtures using a combination of HPLC combined with tandem MS. The most common method of shotgun proteomics starts with the proteins in the mixture being digested and the resulting peptides are separated by HPLC. Tandem MS is then used to identify the peptides.
1) Protein identification results
2) Peptides identification results
