摘要
Objective: To produce fluorescent tagged recombinant erythroferrone protein (ERFE_eGFP) for laboratory investigations. Methods: Erythroferrone (ERFE) gene was fused to green fluorescent protein (eGFP) gene and cloned in a pSecTag2Hygro plasmid. The constructed plasmid was amplified in Escherichia coli DH5. and the eGFP-fused ERFE (ERFE_eGFP) protein was expressed in human embryonic kidney (HEK293T) cell line. Results: The plasmid constructed from colony C6 contained ERFE_eGFP with the correct restriction sizes of 4.2 kb and expressed secretory ERFE_ eGFP fusion protein (approximately size of 75 kDa) in HEK293T cell line. Conclusions: ERFE_ eGFP recombinant protein is successfully expressed as a secretory functional protein and could be sensitively detected using fluorometry. This fusion protein might benefit future applications for localization of cellular ERFE receptors and competitive immunoassay of ERFE concentration.
