Quantification of Insulin and Calf Thymus DNA by a Resonance Rayleigh Scattering Method (CAT#: STEM-ST-0040-YJL)

Introduction

Bovine insulin consists of 51 amino acids in two peptide chains: the A chain with 21 amino acids (Gly A1-Asn A21) and the B chain with 30 amino acids (Phe B1-Ala B30). The A and B chains are connected by two disulfide bridges. Insulin is a physiologically important protein hormone for the control of glucose metabolism and the treatment of diabetes. Therefore, understanding the interaction between insulin and small molecules or biomacromolecules and the development of new determination methods for insulin are of significance for biochemical, pharmacological, clinical and analytical applications.
Calf thymus DNA (DNA from calf thymus) is high-quality double-stranded template DNA isolated from the thymus of male and female calves. Calf thymus DNA can be used to study the interaction between DNA and active molecules.
