The invention relates to the technical field of biological
medicine, in particular to a preparing method and application of a
cell immunologic adjuvant TSA-41 used for a
vaccine adjuvant. According to the preparing method, a
gene sequence SEQ ID NO.1 is artificially designed, the SEQ ID NO.1 recombination
gene sequence is inserted into an
escherichia coli expression
system through the
gene engineering technology, the soluble recombinant
protein TSA-41 with a dipolymer structure is efficiently expressed through
escherichia coli, obtained TSA-41 recombinant
protein is separated and purified, and finally high-purity and high-activity recombinant
protein is obtained. The recombinant protein as the
adjuvant can effectively improve the immune effect of
cell immune type biological vaccines, the technological step of recombinant
protein refolding is omitted, the preparing efficiency is greatly improved, and industrial production is promoted.
