查询词典 geometrical vector

The protozoa were isolated from field animal blood, vectors, pathogenic tissue and secretions. Based on differences of the pathogen morphology, vector species, experimental infected animals, single parasite clone and parasitic tissues, protozoiasis pathogens from different areas and animals in China were isolated and the vectors and transmission mode were also determined by vector transmission trial. Sequence analysis of 18S rRNA gene was used to study the phylogeny of partial isolated protozoa.

Two relevant sites of enzymatic digestion were added to the mTNF-α by PCR. The mTNF-α was linked to the 3'end of m/〓 in pGEX4T-1 vector. The prokaryotic expression vector pGEX4T-1m/〓-mTNF-α was constructed successfully. After induction and expression by IPTG, the expression of two kinds of fusion protein is 15% and 12% of total bacteria proteins respectively. The anti-HCC bifunctional antibodies m/〓-mTNF-α were identified by electrophoresis after the inclusion bodies were purified, denature, renature, re-purified, digested by thrombin and further purified.
