| Abstract: | A variety of heterologus proteins have been produced successfully in Pichia pastoris system which have many particular characteristics in its biology and genetics.Some characteristics and advantages about P.pastoris and the theory of multicopies were reviewed here.How to improve the yield of foreign protein expressed by multicopies integration of foreign genes,and the relationship between copy numbers and yield of expressing,and how to identify the copy numbers,showed far-reaching meaning in theoretics and practice especially in biology pharmacy. |
