Prostate-specific antigen (PSA) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a CM-Sephadex C-50 and by gel filtration on a Sephacryl S-200 column. A single 33-kDa protein band appeared in SDS-PAGE. High pressure liquid chromatography (HPLC) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...
bacteriorhodopsin (br) is the light harvesting and photoactive proton pump found in the membrane of a salt marsh bacteria. this protein has significant potential to use in optical computing and memory devices due to unique intrinsic physical properties of photo and bioelectric. all these features make br one of the most promising protein candidates in protein memories. protein memory is a kind ...

Background: The purpose of this study was to clone, express, and purify a novel multidomain fusion protein of Micobacterium tuberculosis (Mtb) in a prokaryotic system. Methods: An hspX/esxS gene construct was synthesized and ligated into a pGH plasmid, E. coli TOP10 cells were transformed, and the vector was purified. The vector containing the construct and pET-21b (+) plasmid were digested ...
Recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. Genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. Differed methods for protein purification are categorized, based on cast, quality, Easy work and side effect of protein. In this article, we are investigating his His-tag protein pu...
This study was conducted to determine the optimal dietary protein requirement for lemon fin barb hybrid fingerlings. Triplicate groups of fish (1.00 ± 0.05 g) were fed twice a day until apparent satiation with five isocaloric (16 kJ/g) diets containing varying protein level ranging from 20 to 40% for 60 days. Survival was not affected by the dietary protein level. The weight gain and specific g...
