Abstract A water-soluble polysaccharide is a part of the soluble food fibers in bengkuang ( Pachyrhizus erosus ). In previous research, it has been carried out by methods fermentation extraction, adding water and precipitation with ethanol on inulin extraction. recent study was examined effect ultrasound-assisted extraction as new method. This research conducted to obtain for chemical propertie...

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 ...

A soluble rat liver protein that stimulates microsomal methyl sterol oxidase activity has been isolated and purified to homogeneity by salt fractionation, differential heat inactivation, two calcium phosphate gel association, and Sephadex filtration. The protein, as isolated, may be dissociated with detergent into subunits with a molecular weight of approximately 10,300, as determined electroph...

Accumulation of soluble recombinant hemoglobin (rHb1.1) in Escherichia coli requires proper protein folding, prosthetic group (heme) addition, and subunit assembly. This served as a new model system for the study of the effects of temperature, protein synthesis rates, and protein accumulation rates on protein solubility in E. coli. Fermentation expression of rHb1.1 at 30 degrees C from cultures...
