expression of htlv-i p19 protein in an escherichia coli expression system always leads to the formation of inclusion body. solubilisation and refolding of the inclusion bodies is complex, time consuming and difficult during large-scale preparation. this study aimed to express and purify a soluble form of recombinant htlv-i p19 protein in an e. coli expression system. the synthetic dna encoding ...

background: the fc receptor like (fcrl) molecules belong to the immunoglobulin (ig) superfamily with potentially immunoregulatoryfunction. among the fcrl family fcrl2 and 4 are predominantly expressed on memory b cells and fcrl1 is a pan- b cell marker. to date, noligand has been identifid for the human fcrl1, 2 and 4 molecules.objectives: cloning, expression, purifiation and structural analysi...

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...

We describe the construction and use of two sets of vectors for the over-expression and purification of protein from Escherichia coli. The set of pTEV plasmids (pTEV3, 4, 5) directs the synthesis of a recombinant protein with a N-terminal hexahistidine (His(6)) tag that is removable by the tobacco etch virus (TEV) protease. The set of pKLD plasmids (pKLD66, 116) directs the synthesis of a recom...

The efficacy of protein-based medicines can be compromised by their rapid clearance from the blood circulatory system. Achieving optimal pharmacokinetics is a key requirement for the successful development of safe protein-based medicines. Protein PEGylation is a clinically proven strategy to increase the circulation half-life of protein-based medicines. One limitation of PEGylation is that ther...
