Production, purification, and characterization of recombinant maspin proteins.

Production, purification, and characterization of recombinant maspin proteins.

Maspin, a novel mammary serine protease inhibitor, was shown to have tumor suppressing activity (Zou, Z., Anisowicz, A., Hendrix, M. J. C., Thor, A., Neveu, M., Sheng, S., Rafidi, K., Seftor, E., and Sager, R. (1994) Science 263, 526-529). In this paper, we report the production of recombinant glutathione S-transferase-maspin fusion protein, expressed in the bacterium Escherichia coli, and reco...

Design and Construction of Recombinant ELP-Intein Cassette for Use in Simple and new Purification Methods of Recombinant Proteins

Background and Objective: Use of elastin-like proteins (ELPs) provides high-performance protein purification without need for chromatography. In line with cost reduction and facilitation of recombinant proteins purification, which represent a high percentage of production costs, in this project, we eliminated the need for proteases in the process of separation of recombinant proteins from ELP b...

Heterologous Expression, Purification, and Characterization of the HspX, Ppe44, and EsxV Proteins of Mycobacterium tuberculosis

Background: Subunit vaccines are appropriate vaccine candidates for the prevention of some infections. In this study, three immunogenic proteins of Mycobacterium tuberculosis, including HspX, Ppe44, and EsxV as a new construction, were expressed alone and as a fusion protein to develop a new vaccine candidate against tuberculosis infection. Methods: To make the fusion protein, the three genes ...

Recombinant Production and Affinity Purification of the Mature Form of Staphylolysin (LasA) Protein in E.coli

Background and Aims: Enzybiotics are probably the future line of weapons against drug resistant bacteria. They lyse bacteria with the new mechanisms with few likelihood of generating resistance. LasA, which is secreted from Pseudomonas strains degrades Staphylococcus aureus (S. aureus) cell wall and has the potential to use against drug resistant S. aureus infections.  Materials and Metho...
