results escherichia coli phytase was expressed in p. pastoris under different cultivation conditions (post-induction temperature, methanol concentration, and post-induction ph). the optimized conditions by rsm using face centered central composite design were 1% (v/v) methanol, ph = 5.8, and 24.5°c. under the optimized conditions, appa was successfully expressed in p. pastoris and the maximum p...

protein a is a commercially important protein in biotechnological and medicinal applications. the great value of this protein and its applications in genetic and protein engineering and microbial researches as well as the growing use in biochemical industries, biotechnology, medicine and pharmacology, highlight the importance of the present study. in this survey the encoding genes of full-lengt...

objective(s):multi-epitopic protein vaccines and direction of vaccine delivery to dendritic cells (dcs) are promising approaches for enhancing immune responses against mutable pathogens. escherichia coli is current host for expression of recombinant proteins, and it is important to optimize expression condition. the aim of this study was the optimization of multi-epitopic hiv-1 tat/pol/gag/env ...

background: improving the performance of hiv diagnosis assays is one of the most important ways to reduce hiv transmission. because of the high mutation rate of hiv, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. because integrase is one of the most conserved proteins of hiv, it may be a good target for this purpose. in this paper cloning, purification a...

Background Human coagulation factor IX is a 57kDa plasma serine protease made in Liver which plays a vital role in the blood coagulation cascade. FIX deficiency causes severe disorder Hemophilia B or Christmas disease. Nowadays, recombinant proteins have important roles in treatment of diseases. Although, cultivated mammalian cells because of their ability for producing properly folded protein ...
