| description | The invention relates to the field of vaccine preparation, in particular to a preparation method of a recombinant novel coronavirus subunit vaccine. The method comprises the following steps: transfecting plasmids into which a nucleic acid fragment corresponding to RBD-TT recombinant protein is inserted into Escherichia coli; culturing the Escherichia coli to enable the Escherichia coli to expressthe RBD-TT fusion protein, and breaking thalli and separating an inclusion body crude extract of the RBD-TT recombinant protein; dissolving the inclusion body crude extract with a urea-containing denaturing solution, and then performing purifying through anion exchange chromatography to obtain an RBD-TT recombinant protein crude pure sample; diluting the RBD-TT recombinant protein crude pure sample with a diluent; performing filtering, and performing renaturation with a renaturation solution to obtain renaturation protein; and purifying the recombinant protein renaturation protein through anion exchange chromatography |
