General description
Proinsulin, the precursor of insulin and C-peptide, is made by the β cells of the pancreas. Proinsulin formed by the cleavage of pre-proinsulin contains B- and A-domains linked through the connecting domain. Proinsulin interacts with insulin receptor-A (IR-A) isoform present in the nervous system and exhibits antiapoptotic and neuroprotective effects in the developing and postnatal nervous system. Elevated levels of proinsulin serve as a marker for secretory β-cell dysfunction. Increased levels of this hormone are also observed in patients with type 2 diabetes and impaired glucose tolerance. This kit measures the intact and intermediate metabolic forms of human proinsulin.

Proinsulin was first identified as the primary translation product of the insulin gene in Donald Steiner's laboratory in 1967, and was the first prohormone to be isolated and sequenced. While its role as an insulin precursor has been extensively studied
