The High-level Expression of Beet Necrotic Yellow Vein Virus Coat Protein Gene in Escherichia coli
Abstract: The temperature-inducible expression vector containing the beet necrotic yellow vein virus(BNYVV)isolate NM coat protein gene was constructed and transferred into E. coli DH5 . High-level expression of the specific protein was achieved by temperature induction. The results of SDSPAGE and Western blotting show that the expression product which accumulates 19.5% of the total cellular proteins estimated by Shimadzu CS-910 scanning is 21kd BNYVV coat protein.
