The cDNA encoding N-terminal three immunoglobin-like domains of human M-CSFR was linked to His-tag and endoplasmic reticulum retention sequence (KDEL) before being inserted into the genome of tobacco plant, Nicotiana tabacum cv. NC-89, by Agrobacterium tumefaciens-mediated transformation. The insertion and expression of target gene were confirmed by PCR, ELISA, and Western blot. The recombinant M-CSFsR reached a maximum expression level of 1.92% of total soluble protein in transgenic tobacco plant leaf tissues. The recombinant M-CSFsR could be purified through a one-step IMAC process and its bioactivity was confirmed by the inhibition of colony formation of J6-1 cells. The results suggested that we successfully expressed a high level of bioactive human M-CSFsR in tobacco plants.
