摘要:
The present invention relates to a preparation method using a fusion expression partner. The method includes preparing a polynucleotide encoding a fusion expression partner selected from the group consisting of SlyD (FKBR-type peptidyl prolyl cis-trans isomerase), Crr (glucose-specific phosphotransferase (PTS) enzyme IIA component), RpoS (RNA polymerase sigma factor), PotD (Spermidine/putrescine-binding periplasmic protein), and RpoA (RNA polymerase alpha subunit), and an expression vector linking a polyDNA fragment of a heterologous protein, preparing a transformant by introducing the expression vector into a host cell, inducing the expression of a recombinant protein by culturing a transformant, and obtaining the expression. In the preparation method of the recombinant protein, the heterologous protein may enhance the water-solubility and folding of the recombinant protein, overcome the limitations about the water-solubility and folding which the conventional fusion expression partners have, and be used widely in the production of pharmaceutical and industrial proteins.
摘要:
Provided herein is a surface acoustic wave (“SAW”) sensor device including an isolation component of a target biomolecule. A sample containing the target biomolecule is separated by its size using electrophoresis, and sequentially reacts with a SAW sensor. In other words, the device is capable of detecting the target biomolecule by separating biomolecules using electrophoresis, and applying the separated biomolecules to the SAW sensor.
摘要:
A highly sensitive method of assaying an analyte present in a sample using protamine is provided, as well as an immunoassay reagent and biosensor that reduces non-specific binding by electrostatic interaction of protamine with fibrinogen present in the sample.
摘要:
Provided are a sensor for detecting molecular binding by increasing the mass of a gold nanoparticle through light-irradiation and a method thereof. In the method, light-irradiation increases the size of gold nanoparticles without using a reducing agent, to enhance the mass. Accordingly, selectivity may be improved, and the sensitivity of detection may be improved due to a change in various properties of a gold nanoparticle.
