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.
