SDS-PAGE analysis of cTnI enrichment from human serum spiked with dilated cardiomyopathy and postmortem cTnI-containing sarcomeric extracts also revealed consistent HSA depletion by the NP-Pep, in contrast with the Agarose-Pep and Agarose-mAb (Supplementary Fig. 20). The gene discussed is ALB; the disease is dilated cardiomyopathy.
