The recent introduction of electrospray ionization techniques that are suitable for peptides and whole proteins has allowed for the design of mass spectrometric protocols that provide accurate sequence information for proteins. The advantages gained by these approaches over traditional Edman Degradation sequencing include faster analysis and femtomole, sometimes attomole, sensitivity. The ability to efficiently identify proteins has allowed investigators to conduct studies on their differential expression or modification in response to various treatments or disease states. This powerful technique has been instrumental for the study of proteins and markers associated with various disorders, including heart disease, cancer, and cystic fibrosis.
Abvigen can provide accurate sequencing results. The higher the purity of the customer's sample, the better. The report we deliver includes experimental steps, mass spectrum parameters, details of N-terminal and C-terminal sequences of proteins, mass spectrum images and original data.
