General description

SILu Prot Insulin is a recombinant, stable 15N isotope-labeled human Insulin Expressed in P. pastoris, it is designed to be used as an internal standard for bioanalysis of Insulin in mass-spectrometry. SILu Prot Insulin is a disulfate bonded hetero-dimer protein composed of two chains. Chain A of 21 amino acids and a thoretical amolecular mass of 2408.5; Chain B of 30 amino acids and a thoretical amolecular mass of 3468.7 (Note that Thr30 in chain B is not 15N labeled).

Biochem/physiol Actions

Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.



Physical form

Supplied as dried pellet from a solution containing 1% acetic acid.
