Troponin I, Cardiac (cTnI) (AP)

May be stored at 4 degree C before opening. DO NOT FREEZE! Stable at 4 degree C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months after receipt. 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. Freezing alkaline phosphatase conjugates will result in a substantial loss of activity.

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 aa169-178 of cTnI. Crossreactivity with skeletal Troponin I is < 10%.
