The host for pGEX vector and GST tagging
GST Tag is one of top techniques in biotechnology laboratory that use as an economic easy strategy for protein separation, purification and detection. The host for this process is important for FDA approved and top resolution result. E. coli as a pioneer organism used in the laboratory for bio engineering is one of the main …
Short review to GST Tag protein
GST Tag protein is one of important amino acid sequences that used for protein engineering for protein purification and protein detection purposes. The GST Tag known as The Glutathione S-transferase (GST) is a Gene Fusion System that use for the expression, purification, and detection of fusion proteins produced in Eschericia coli and FDA approved organism …
What is the best binary expression system for drosophilagenetics? Short fast 1 minute answer!
Binary expression systems: GAL4-UAS, LexA-lexAopand QF-QUASsystems The GAL4-UASsystem is the workhorse of Drosophilagenetics, and few papers are currently published that do not use it.
Does the H tag work as a solubility enhancer? Short fast 1 minute answer!
Regarding the H tag, it did not function as a solubility enhancer tag, but it improved the production levels of target proteins in E. colisimilarly to the Fh8 tag (Costa et al., 2013a).
How do solubility fusion tags produce soluble proteins? Short fast 1 minute answer!
The ability of solubility fusion tags to produce soluble protein is only the first step in the pathway towards protein production. As many of these tags are large proteins, it is often necessary to remove the tags after they have been used to make soluble fusion partners.
What is Intein Mediated Purification ? Short fast 1 minute answer!
One of the purification methods used in the biotechnology laboratories for better detection and separation is Intein mediated purification techniques. The intein-mediated purification system has the potential to significantly reduce the recovery costs of industrial recombinant proteins. The ability of inteins to catalyze a controllable peptide bond cleavage reaction can be used to separate a …

What is the difference between bioID and biotinylation? Short fast 1 minute answer!
Biotinylation protein is one technique used in biotechnology for tagging the proteins. In BioID, the protein of interest is fused to a “promiscuous” biotin ligase and stably expressed in cells; the fusion protein biotinylated proximal proteins only when excess biotin is added to the medium. High-affinity avidin/streptavidin-beads are used to capture biotinylated candidates in a …
How can I incorporate solubility enhancers into my fusion tag design? Short fast 1 minute answer!
Fusion tags can be incorporated using different strategies: affinity and solubility tags are set individually or together, and sites for protease cleavage are designed between the fusion tags and target proteins. Solubility enhancer partners
What is a maltose-binding protein? Short fast 1 minute answer!
Maltose binding protein is one of the preparation and separation techniques used in biotechnology laboratories. Maltose-binding protein ( MBP) is a part of the maltose / maltodextrin system of Escherichia coli, which is responsible for the uptake and efficient catabolism of maltodextrins. It is a complex regulatory and transport system involving many proteins and protein …
