C-Peptide — frequently asked
What is C-peptide?
C-peptide is the 31-residue connecting segment of proinsulin that joins the insulin B and A chains. It is cleaved out during granule maturation and secreted from pancreatic beta cells in equimolar amounts with insulin.
Why is C-peptide measured in research?
Because it is co-secreted with insulin but cleared differently, C-peptide is widely used in laboratory models as an index of endogenous beta-cell secretory activity, particularly where exogenous insulin would confound direct insulin measurement.
Which species variants are available?
Human C-peptide is the most common, with rat C-peptide 1 and C-peptide 2 offered separately because rodents carry two insulin genes producing non-identical connecting peptides. Species matching is essential for immunoassay standards and antibodies.
