C Peptide is part of the molecule of Proinsulin, that consists of three parts: C Peptide and two long strands of amino acids (called the alpha and beta chains) that later become linked together to form the insulin molecule. From every molecule of proinsulin, one molecule of insulin plus one molecule of C Peptide are produced. C peptide is released into the blood stream in equal amounts to insulin. A test of C peptide levels will show how much insulin the body is making. Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
Our Abpromise guarantee covers the use of ab1975 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ELISA||Use at an assay dependent concentration.
Competitive ELISA or RIA detection of C-peptide in human serum after immunospecific removal of proinsulin (with solid-phased Mabs to human proinsulin). Construction of a sensitive two-site sandwich EIA/ RIA immunosorbent assay for the measurement of total human proinsulin (including proinsulin convertion intermediates) in serum. Specific immunosorbtional removal of total proinsulin and C-peptide molecules from serum samples (with solid-phase of this antibody) before the measurement of human insulin.
|RIA||Use at an assay dependent concentration.|
|IHC-P||Use a concentration of 0.1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
IHC image of C Peptide staining in Human Pancreas formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab1975, 0.1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
ab1975 has not yet been referenced specifically in any publications.
