C-Peptide (FITC)

May be stored at 4 degree C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degree C. Aliquots are stable for 12 months after receipt at -20 degree C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. FITC conjugates are sensitive to light.

Recognizes human free C-peptide and C-peptide region in proinsulin molecules. Antigenic determinants identified by Mab are in the three-dimensional structure generated by N- and C-terminal regions of C-peptide separated by beta-turn at position 47-50 of proinsulin. Does not crossreact with human, bovine, porcine and mouse/rat insulin.
