The basics of hplc peptide analysis
WebThe introduction of high-performance liquid chromatography (HPLC) to the analysis of peptides and proteins some 25 years ago revolutionized the biological sciences by enabling the rapid and sensitive analysis of peptide and protein structure through the exquisite speed, sensitivity, and resolution that can be easily obtained. WebPeak ratios have been previously employed for analysis of peptides on surfaces 43 and for analysis of functional groups on polymeric surfaces. 38 After the peptide was added to the polymer scaffold, the peak ratio of –CH 3: N 3 significantly increased (Fig. S3, ESI†) indicating the click reaction proceeded as expected, where the methyl groups should …
