This has been reported in cultured neonatal rat cardiomyocytes93 the place peptide-mediated integrin agonism was demonstrated to lead to amplified cTnI launch during the absence of necrosis [assessed by LDH assays and nuclear propidium iodide staining].
Figure one. Evolution of your cardiac troponin (cTn) assays and their diagnostic cutoffs.
