Technical Data
C-Peptide (Hyperproinsulinemia, Insulin Precursor, Proinsulin)
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 bloodstream in equal amounts to insulin.

Suitable for use in RIA, ELISA and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
ELISA: Capture antibody
Immunohistochemistry: Frozen sections
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Synthetic human C-peptide (BSA).
Purified by caprylic acid and ammonium sulfate precipitation.
Supplied as a liquid in PBS, pH 7.2, 0.09% sodium azide.
Recognizes human C-peptide, proinsulin and the central part of the C-peptide molecule, probably with the hydrophilic segments 8-13 and 25-31. Does not react with human, bovine or porcine insulin, glucagon or somatostatin. Cross-reactivity: C-peptide, 100%; human proinsulin, 87%.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
