Depositors Notes: This antibody recognizes the C-peptide (aa 33-63 of proinsulin) which separates insulin B chain (aa 1-30) from insulin A chain (aa 66-86) in the proinsulin protein. Stains C-peptide in mature granules and proinsulin in immature granules of islet beta-cells. The antibody does not cross-react with rodent C-peptide/proinsulin.

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable.
To ensure retention of antibody activity, we recommend aliquotting the product into two parts:
1) a volume of antibody stored at 4°C to be used within two weeks.
2) the remaining product diluted with an equal volume of molecular grade glycerol and stored at -20°C.
While optimal Ig concentration for an application will vary, a good starting concentration for immunohistochemistry (IHC),
immunofluorescence(IF) and staining is 2-5 µg/ml.
For Western blots, the concentration is decreased by one order of magnitude (that is, 0.2-0.5 µg/ml).
All cell products contain the antimicrobial ProClin. See our FAQ section for additional information.
