Presence of which of the following in the expression of vector ensures increase in the yield of recombinant protein produced?

Ans. A. Inducible promoter.a. The primary advantage of an inducible promoter expression system is that production of the recombinant protein can be biochemically controlled, allowing for the separation of unique growth and production phases of the culture.b. During the growth phase, the culture is rapidly grown to high cell density prior to induction without the extra metabolic burden of exogenous protein production, thus minimizing the nonproductive period of the culture. Induction of the culture at high cell density ensures that the volumetric production will be maximized.c. Thus, a Inducible promoter in the expression of vector increases the yield of recombinant protein produced.d. Given the importance of protease inhibitors, characterization of protease inhibitors, which can play a role in preventing, ameliorating or correcting dysfunctions and diseases.
