 Applicable sample 
Culture Supernatant, Plasma, Serum, Urine
This enzyme immunoassay (EIA) kit is a stable and convenient assay system for rat C-peptide in its plasma, serum, urine and culture supernatant.
The processing of proinsulin, which occurs within the B cell, yields insulin and C-peptide and insulin and C-peptide are secreted in equimolar quantities into blood circulation. Therefore, the measurement of C-peptide in blood reflects the concentration of insulin and also provides valuable information to evaluate the pancreatic B cell function.
The EIA kit is using synthetic rat C-Peptide I as standard and biotinylated rat C-Peptide I as labeled antigen. The kit contains specific polyclonal antibody (C-peptide antibody) recognized to the amino acid sequence in the C-terminal side region which are common between rat C-Peptide I and II.
