Creative BioMart Seminar—for Recombinant Proteins Development

Creative BioMart, a world leading biotech company specialized in the supply of quality proteins, recombinant proteins, GMP proteins, and custom protein services, etc., launched a seminar to discuss the development of a more comprehensive list of recombinant proteins. Paricipants inlcude Creative BioMart staff scientists and sale staff. Holding this seminar, Creative BioMart aims to expand its providing for recombinant protein products.

Recombinant protein production has become an essential tool for providing the necessary amounts of a protein of interest to either research or therapy by providing adequate amounts of proteins for studying protein structure and function. Moreover, scaled-up facilities produce recombinant vaccines, hormones, antibodies, growth factors, blood components, and enzymes.

Creative BioMart is a well recognized brand for over 50,000 recombinant proteins for diverse researches around the world, ranging from proteins, cytokines, enzymes, hormones, kinase, chemokines to others.

Linna Green, the chief marketing staff in Creative BioMart, said in the seminar that “We found out that our customers’ needs for recombinant proteins is increasing by the day. So we decided to develop and introduce more products of this kind with our current products quality assured. We must work harder for early results. Guaranteed by our advanced technologies and facilities, we do believe the day is now faraway to come.”

Through this seminar. Creative BioMart got further advance in the development of recombinant proteins though it has already stood out in reputation and product quality.

Yeast Expression System Service in Creative BioMart

Yeast systems have been a staple for producing large amounts of proteins for industrial and biopharmaceutical use for many years. It is the most economical eukaryotic expression system for both secretion and intracellular expression. And it’s ideally suitable for large-scale production of recombinant eukaryotic proteins.

Take advantage of Creative BioMart's proprietary YeastXceedTM Technology, selected stable and durable production strains that resemble mammalian system are employed for high-yield, high-productivity protein processing, thus dramatically reducing the associated costs and inherent time requirements.

With expertise in protein expression spanning both P. pastoris and S. cerevisiae expression systems, Creative BioMart is the right choice for protein production via fed-batch pichia processes. The company’s staff can move help move your project forward.

Engineering-enhanced protein expression technologies in Creative BioMart will enable a high success rate over 95% over various recombinant proteins. And the proprietary YeastXceedTM technology is pushing the yields even higher. Many secretory proteins that bacterial expression systems yield as insoluble or as inactive inclusion bodies can be produced successfully by the company’s yeast expression system using native or yeast secretion signals.

In the past years, we have identified DNA elements that are instrumental in increasing translation rates when included in recombinant protein expression vectors. These elements are functional across eukaryotic production platforms, including mammalian cells, yeast and most fungal systems. On the basis of these elements, the company developed proprietary HostOptimTM technology that has been confirmed for a wide variety of industry relevant platforms.

Mammalian Two-Hybrid System Offered by Creative BioMart

Two-hybrid systems are extremely powerful methods for detecting protein-protein interactions in vivo. Of note, Creative BioMart Mammalian Two-Hybrid Assay allows rapid and convenient analysis of protein-protein interactions in transfected mammalian cells. 

This assay uses a SEAP secreted reporter to measure the interactions between the two proteins of interest, eliminating the need for cell lysis. Because this two-hybrid assay is performed in mammalian cells, proteins encoded by mammalian cDNAs are more likely to be in their native conformation; therefore, post-translational modifications and experimental results are more likely to represent biologically significant interactions.

Features
Fast, convenient analysis of protein-protein interactions in mammalian cells
SEAP secreted reporter eliminates the need for cell lysis
Biologically relevant results are more likely in a mammalian system

Applications
Confirm protein-protein interactions in mammalian cells
Map interacting domains

A noteworthy point of preference of the mammalian two-hybrid assay over yeast two-hybrid system is that protein-protein interactions are considered in mammalian cell lines. Accordingly, this assay empowers specialists to study communications between mammalian proteins that may not fold accurately in yeast or that require post-translational modification or external stimulation that is not present in yeast.

Experts at Creative BioMart could be glad to discuss the details of intended interaction studies with its valued customers and develop experimental methods and strategies tailored to its customers'requirements. Customers can contact at contact@creative-biomart.com for more information.

Industry News Roundup for February, 2016: Biotech

A novel self-enhanced electrochemiluminescence immunosensor based on hollow Ru-SiO2@PEI nanoparticles for NSE analysis

Poly (ethylenimine) (PEI) and Ru(bpy)32+-doped silica (Ru-SiO2) nanoparticles were simply mixed together to prepare a novel self-enhanced electrochemiluminescence (ECL) composite of Ru-SiO2@PEI. The hollow Ru-SiO2@PEI nanoparticles were used to build an ECL immunosensor for the analysis of neuron specific enolase (NSE). PEI not only assembled on the surface of Ru-SiO2 nanoparticles through the electrostatic interaction to act as co-reactant for Ru(bpy)32+ ECL, but also provided alkaline condition to etch the Ru-SiO2 nanoparticles to form the hollow Ru-SiO2@PEI nanoparticles with porous shell. The unique structure of the Ru-SiO2@PEI nanoparticles loaded both a large amount of Ru(bpy)32+ and its co-reactant PEI at the same time, which shortened the electron-transfer distance, thereby greatly enhanced the luminous efficiency and amplified the ECL signal. The developed immunosensor showed a wide linear range from 1.0 × 10−11 to 1.0 × 10−5 mg mL−1 with a low detection limit of 1.0 × 10−11 mg mL−1 for NSE. When the immunosensor was used for the determination of NSE in clinical human serum, the results were comparable with those obtained by using enzyme-linked immunosorbent assay (ELISA) method. The proposed method provides a promising alternative for NSE analysis in clinical samples.

Bial's Fatal Clinical Trial in France Had Already Caused Deaths of Dogs in Earlier Tests

PARIS – An experimental chronic pain treatment that caused one death and left five others with possible brain damage in a French clinical lab was believed to be related to deaths in dogs in earlier clinical testing, the Telegraph of London reported this morning.

The Telegraph reported the details of the canine deaths were not reported by the laboratory conducting the tests for Portugal-based Bial-Portela were not disclosed due to “industrial secrecy.” The trial was being conducted by Bial, a clinical research organization in Rennes, France. Citing a report in the French paper Le Figaro, the Telegraph said a “number of dogs” died and others suffered neurological damage in preclinical trials of the drug. Bial has refused to reveal information about the preclinical data and the canine deaths.

Bacteria take 'RNA mug shots' of threatening viruses

Scientists from The University of Texas at Austin, the Stanford University School of Medicine and two other institutions have discovered that bacteria have a system that can recognize and disrupt dangerous viruses using a newly identified mechanism involving ribonucleic acid (RNA). It is similar to the CRISPR/Cas system that captures foreign DNA. The discovery might lead to better ways to thwart viruses that kill agricultural crops and interfere with the production of dairy products such as cheese and yogurt.
