Interpolated concentration of native C-Peptide was measured in duplicate at different sample concentrations in 96-well vs. 384-well plates. Undiluted samples are 12.5% human serum. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). Sample dilutions are made in Sample Diluent NS.

Serum from three individual human male donors with type 2 diabetes was measured in duplicate.
Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean C-Peptide concentration in type 2 diabetes serum samples was determined to be 1.9 ng/mL with a range of 1.4 – 2.2 ng/mL.

Interpolated concentrations of native C-Peptide in human serum, plasma (heparin) and pooled-sex urine samples.
The concentrations of C-Peptide were measured in duplicates, interpolated from the C-Peptide standard curves and corrected for sample dilution. Undiluted samples are as follows : serum 12.5%, plasma (heparin) 12.5%, and urine 1 : 200. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean C-Peptide concentration was determined to be 1.3 ng/mL in serum, 0.6 ng/mL in plasma (heparin), and 31.7 ng/mL in pooled-sex urine.

Product details
Human C-Peptide ELISA Kit ab260064 is a rapid single-wash 90-min sandwich ELISA kit to measure Human C-Peptide in Serum, Heparin Plasma, Urine, Cell culture media, and Heparin Plasma. This Simplestep sensitivity is 1.45 pg/mL.
How the assay works
Human C-Peptide SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
This immunoassay is calibrated against a highly purified human C-Peptide. The NIBSC/WHO unclassified purified human C-Peptide preparation 13/146 was evaluated in this kit. The dose response curve of the unclassified standard C-Peptide parallels the SimpleStep standard curve. To convert sample values obtained with the SimpleStep Human C-Peptide kit to approximate NIBSC mg/mL, use the equation below.
NIBSC (13/146) approximate value (mg/mL) = 1.077 x SimpleStep Human C-Peptide value (mg/mL).

C-peptide of insulin is a cleavage product produced during processing of the insulin pro-hormone to the mature insulin molecule. Proinsulin is cleaved when it is released from the pancreas into the blood - one C-peptide for each insulin molecule. C-Peptide has been shown to bind to a variety of cell types, and in vivo animal diabetes models have shown positive effects on kidney and nerve function.

Biological function summary
C-peptide plays a role beyond being a mere byproduct of insulin synthesis. Experiments have shown it binds to cell membranes indicating it functions independently and is more than part of the insulin processing complex. Studies suggest C-peptide may have physiological effects such as improving blood flow and possessing anti-inflammatory properties. Its ability to bind likely involves specific interactions that suggest possible receptors a subject of ongoing research. Detection methods like peptide ELISA and peptide test kit further facilitate studying its biological activity and potential therapeutic implications.
Pathways
C-peptide is closely linked to the metabolic insulin signaling pathway. This pathway is integral in glucose homeostasis and involves proteins such as insulin receptor and glucose transporter. Although not directly involved in the receptor-mediated actions of insulin C-peptide's presence alongside insulin shortly after release places it within this critical pathway. Another related pathway includes peptide hormone responses where C-peptide might influence vasodilation or cellular signaling revealing potential avenues for regulating metabolic conditions.
