Methods Eukaryotic expression plasmid pCMVCD was constructed , and identified by re2 striction endoenzyme digestion. CD gene was transfected into NSCs from new2born Wistar rats using Lipofec2tamine2000. Positive clones (named NSCs/ CD cells) were screened by G418 presence. 52Fluorocytosine (52FC) ad2ministration of different concentrations were incubated with NSCs/ CD cells. NSCs/ CD cells viability ratios were mea2 sured by MTT assay.

After thermal induction, no specific recombinant protein band in SDS-PAGE was found, but G-CSF activity was detectable. Therefore, a new recombinant plasmid pBVHG2 expressing hG-CSF hybrid protein with additional 8 amino acids which could be cut off specifically with the help of mucosal enterokinase at the N terminus of hG-CSF was constructed.
含此质粒菌株虽然表达菌体裂解后可测得明显的生物学活性,但SDS-PAGE仍未见特异表达产物带;因此,再应用相同方法,在hG-CSF cDNA突变体5′端增加24核苷酸对的FLAG肽编码序列,构建了hG-CSF杂交蛋白(hG-CSF天然蛋白N末端增加8aa的FLAG肽,后者可由肠激肽酶切除)的表达质粒pBVHG2。

The novel primers were evaluated by detecting BTV serotypes 1, 3, 5, 8, 10, 11, 21 and 22. The specificity of the primers was estimated by comparing to gene sequences of viruses published in GenBank, and further assessed by detecting BTV serotype 1-12 and Epizootic hemorrhagic disease virus serotype 1-4. The sensitivity and repeatability of PCR with the novel primers were evaluated by successfully detecting the recombinant plasmid pGEM-T121 containing the diagnosed nucleotide sequence.
