Reversed-Phase HPLC Analysis of Insulin Variants and Analogs by UV and Mass Spectral Detection

Insulin is an approximately 6000 Da peptide hormone used to regulate the glucose concentration in blood. There are several different forms of insulin that are both natural and recombinant; the recombinant forms have been engineered to improve pharmacokinetic properties. A quick and reliable chromatographic technique was developed to identify and detect a mixture of insulin variants in an unknown sample.
