Purity：Purified by Protein A affinity chromatography. >90% Purity is tested by electrophoresis.
Form：Supplied as a liquid in PBS, pH 7.2. No preservative added. No stabilizing proteins added. Labeled with Fluorescein isothiocyanate (FITC).
Specificity：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.
