Description
The U8-424 monoclonal antibody specifically binds to human, mouse, and rat C-Peptide, the connecting peptide that links the A- and B-chains in the proinsulin molecule. The A- and B- chains and C-Peptide are encoded by the transcript of the INS gene and are produced by the β cells in the islets of Langerhans of the pancreas. As the biosynthesis of insulin proceeds, the C-Peptide is cleaved from proinsulin to form the mature insulin hormone, which is composed of the A- and B-chains linked by 2 disulfide bonds. Mature insulin and C-Peptide are stored in granules in the β cells and are released to the blood in response to metabolic signals such as glucose, the amino acids arginine and leucine, and acetylcholine. As a result, C-Peptide is released into the blood stream in an equimolar amount to insulin; the serum level of C-Peptide correlates with pancreatic β cell function and the amount of insulin being produced. The expression of C-Peptide can be used to monitor the pancreatic differentiation of pluripotent stem cells. Insulin is an evolutionarily conserved peptide hormone that binds to receptors on target cells (primarily adipose and muscle) to promote the absorption of glucose from the blood, thus regulating fat and carbohydrate metabolism. C-Peptide itself binds to many cell types, independently of the insulin receptor, and initiates several intracellular signaling cascades.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

2. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
6. An isotype control should be used at the same concentration as the antibody of interest.
7. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
