Specific for cardiac troponin I (cTnI), epitope 169 - 178 a.a.r. Cross-reactivity with skeletal TnI is less than 10 %. Can be used for cTnI immunoassay; cTnI immunoprecipitation, immunohistochemistry, immunoaffinity purification; works in WB. Recommended pairs for for quantitative sandwich immunoassay (coating - conjugate): M18 + 560 (mixture for coating) - 19C7 + 267 (mixture for detection), MF4 + 560 (mixture for coating) - 19C7 + 267 (mixture for detection).
