Human Transcobalamin I (TCN1) ELISA Kit

Quantitative protein measurement of the vitamin B12 carrier haptocorrin is enabled by this Assay Genie ELISA kit, supporting research into cobalamin metabolism. Transcobalamin I (TCN1) is a ~60 kDa glycoprotein that binds the majority of circulating vitamin B12 and circulates in human plasma, saliva, and other bodily secretions. Elevated TCN1 concentrations have been reported in myeloproliferative disorders and hepatocellular carcinoma, making the protein a useful biomarker for related studies. The microplate-based assay uses a colorimetric readout compatible with standard laboratory workflows, and reagents are packaged in ready-to-use vials for in vitro research applications.
