Purity:>90%. Protein A Sepharose Chromatography. Purity is tested by electrophoresis.
Form:Supplied as a liquid in PBS, pH 7.2. No preservative added. No stabilizing proteins added. Labeled with R-Phycoerythrin (PE).
Specificity:Reacts equally with free cardiac troponin I (cTnI) and cTnI forming complexes with other troponin components. Not affected by heparin, phosphorylation and oxidation. Recognizes an epitope located between amino acid residues 25 and 40. No crossreactivity with skeletal muscle troponin I.
