A simple and dual expression plasmid system in prokaryotic (E. coli) and mammalian cells

Dual-expression vectors for efficient protein expression in both E. coli and mammalian cells.

The modified recombinant proinsulin: a simple and efficient route to produce insulin glargine in E. coli

Background: Recombinant insulin glargine, a long-acting analogue of insulin, is expressed as proinsulin in host cell and after purification and refolding steps cleaved to active insulin by enzymatic digestion using trypsin and carboxypeptidase B. Since the proinsulin's B and C chains have several internal arginine and lysine residues, a number of impurities are generated following treatment wit...

cloning and expression of reteplase in e. coli using different prokaryotic promoters

Over Expression of Influenza Virus M2 Protein in Prokaryotic System

Background and Aims: Influenza A virus of Orthomyxoviridae family is able to create pandemic influenza. Vaccination is the most effective way to prevent influenza virus infection. Matrix protein 2 (M2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. Materials and Methods: We...

CLONING AND EXPRESSION OF A HUMAN INTERFERON a2 GENE IN E. COLI

The plasmid pALCA1SIFN containing cDNA that encodes the human interferon a-2b was obtained from the ATCC(no. 531667). In this system the expression of the gene is under the control of an alcA promoter. alcA p is a specific promoter for expression of different genes in Aspergillusfilamentous. In this plasmid the coding region of IFN?-2b is preceded by the coding region of a synthetic signal ...
