C-Peptide Antibody (790904) [Unconjugated] - C-Peptide

C-Peptide was detected in immersion fixed BG01V human embryonic stem cells differentiated into pancreatic beta cells using Mouse Anti-Human C-Peptide Monoclonal Antibody (Catalog # MAB14171) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

C-Peptide was detected in immersion fixed paraffin-embedded sections of human pancreas using Mouse Anti-Human C-Peptide Monoclonal Antibody (Catalog # MAB14171) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counter-stained with hematoxylin (blue). Specific staining was localized to the cytoplasm of islet cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

iPSC-derived beta islets were fixed, frozen, and sectioned. Sections were stained with a Mouse Anti-Human C-peptide Monoclonal Antibody (Catalog # MAB14171), and a Rat Anti-Human/Mouse Somatostatin Monoclonal Antibody (Catalog # MAB2358), followed by secondary antibody staining with the NorthernLights NL493-conjugated Donkey Anti-Mouse IgG Antigen Affinity-purified Polyclonal Antibody (Catalog # NL009; green) and NorthernLights NL557-conjugated Goat Anti-Rat IgG Antigen Affinity-purified Polyclonal Antibody (Catalog # NL013; red). Cell nuclei were stained with DAPI (Catalog # 5748; blue) and the images were overlaid.

Background

Insulin is a peptide hormone that facilitates the cellular uptake of glucose by regulating the appearance of membrane glucose transporters. The single chain insulin propeptide consists of a 30 amino acid B chain (aa 25-54), a C-Peptide (aa 55-89), and a 21 aa A chain (aa 90-110). Removal of the C-Peptide by proteolysis enables the formation of mature Insulin, a disulfide-linked heterodimer of the A and B chains. Circulating C-peptide levels are elevated in hyperinsulinism, obesity, and type II diabetes. The human C-Peptide shares 61% and 68% aa sequence identity with mouse and rat C-Peptide, respectively.
