摘要:
The present invention relates to a gene of swine vesicular disease virus (SVDV) and the mutant strains of the gene, and the expression plasmids, the preparation process thereof. The invention also relates to a vaccine for use in the prophylaxis of swine vesicular disease composition containing the mutant strains. Furthermore, the invention provides a process for differentiating mutant strains of SVDV from the wild type strain of SVDV, coxsackievirus and foot-and-mouth disease virus by polymerase chain reaction.
摘要:
The present invention provides a genetically recombinant xylanase with high yield and good activity, and a process for the production of the recombinant xylanase. The present invention also provides the coding sequence of the recombinant sequence, vectors bearing the coding sequence and the transformants containing the vectors. The present invention further provide a column wherein the recombinant xylanase is immobilized.
