Expression of the Mature Protein Gene of Chicken γ-Interferon and the Detection for the Antiviral Activity of the Purified Expression Product
Abstract: Using the total mRNA in the lymphocyte in chicken blood as the template, the mature protein gene of interferon γ-interferon was cloned and amplified through the reverse transcription polymerase chain reaction. The gene was then ligated to pRLC to establish the gene’s non-fusion expressing vector. The best inducing time for the expression of this recombinant protein was tested through inducing the expression of positive selected plasmid with different time span. This expressed product was then denatured and renatured and was added to the culture medium with CEF, which were attacked by the 100 TCID50 VSV. The result showed that the activity of the recombinant protein was up to 1.0×106 U/mg.
