Characterization and optimization of ArtinM lectin expression in Escherichia coli

Characterization and optimization of ArtinM lectin expression in Escherichia coli

BACKGROUND ArtinM is a d-mannose-specific lectin from Artocarpus integrifolia seeds that induces neutrophil migration and activation, degranulation of mast cells, acceleration of wound healing, induction of interleukin-12 production by macrophages and dendritic cells, and protective T helper 1 immune response against Leishmania major, Leishmania amazonensis and Paracoccidioides brasiliensis inf...

Cloning and optimization of phytase enzyme gene expression in Escherichia coli

Introduction Phytase is an enzyme that has the ability to break down phytic acid into myoinositol and mineral phosphate, and widely uses as an additive in animal foods. The aim of this study was to achieve a high level of bacterial phytase expression in PET26b expression host. Materials and Methods To generate the recombinant phytase enzyme, the target gene was introduced into the expression ...

optimization of the expression of reteplase in escherichia coli

reteplase is a segment of tissue plasminogen activator used for the removal of thrombi in blood vessels. in the present study the cloned reteplase gene was used for its expression in competent e. coli. the  recombinant plasmid, pet15b/reteplase (rpet-bl21), was transformed into competent e.coli strain bl21 (de3) cells. overnight culture of the transformed bacteria was induced by the addition of...

Enhanced Expression of Recombinant Activin A in Escherichia coli by Optimization of Induction Parameters

Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli was done by using the response surface methodology (RSM). At this stage, the effect of IPTG and la...
