Gene and Cell Therapy rely on the use of modified viruses as vectors to transfer genes into cells that they are able to infect. The authors specifically noted the importance of mammalian cell systems in their study: “The architecture of these constructs allows for straightforward production in cell culture. Presented by Mathieu Porte, R&D Production  Manager at Polyplus-transfection® September 21 , 1:00 – 1:30 PM PST, Presented by Mégane Denu, R&D Engineer Bioproduction at Polyplus-transfection® August 26th , 11:25-11:45 AM EST. The combination of flexibility offered by the technique with high-quality reagents leads to the expression of functional proteins for diverse applications. The bacterium Escherichia coli served as the main expression system for a long time. NEW! In comparison to competitors, the use of FectoVIR®-AAV results in a 10-fold increase in functional titer yields in suspension cells. Talk: Next-Generation Transfection Reagent for Large Scale AAV Manufacturing, Talk: Supporting viral vector therapies from PD to commercialization, enable access to dual sourcing for reagents. However, these viruses require cell division to occur in order to integrate the viral DNA (thus limiting in vivo application). They offer substantial advantages in terms of reliability, safety and costs for nucleic-acid based therapies. VWR is your complete source for workplace supplies. AAVs have a much smaller genetic capacity compared to that of standard adenoviral vectors, however, transduced cells are minimally immunogenic, and they have been praised for their safety profiles and use for in vivo. Dr. Andreas Rummelt has held executive management positions internationally for more than 20 years in the pharmaceutical industry, focused in the areas of manufacturing, quality, and technical matters. After purification, recombinant proteins from 6 of the 7 serotypes were used to develop a hexavalent vaccine to immunize mice and non-human primates. Click on YES to subscribe to our newsletter (few emails/year). To overcome this challenge, Davis-Gardener et al., 2020 innovatively developed a bispecific antibody that combines the variable domain of already available bNAbs against the V2-glycan and V3-glycan regions of the HIV-1 envelope glycoprotein. Choose among a broad range of powerful transfection reagents specifically developed to enable you to reach the desired level of protein expression in a wide range of adherent and suspension mammalian cell types, primary and cell lines. carry their genetic material in the form of RNA. Many diseases can be traced to a faulty version of vital genes. In a similar approach, Kamp et al., 2020 expressed a recombinant protein that integrated the outer surface protein A (OspA) of bacteria Borrelia, which causes Lyme disease, with ferritin from Helicobacter pylori. For more information, call 1.888.793.2300 or email us at For example, Kaku et al., 2020 expressed recombinant antibodies in suspension HEK293 cells using FectoPRO® with mutations in specific residues to assess changes in the antibody-antigen interaction. We set science in motion to create a better world. For more information, please visit the Polyplus-transfection® web site at: In order to process your orders without delay, we request that you provide the required business documentation to purchase this product. These viral vectors do not integrate into the genome of the host cells, but rather persist with the cells as episomal DNA. For this, scientist engineer plasmid DNA or mRNA coding for a gene of interest that is transfected into mammalian cells to force transient production of the protein of interest. The Polyplus solution involves the development of dedicated transfection reagents depending upon the viral vector type required. These appointments underscore our commitment to attracting the best talent in biotechnology which in turn delivers value for our customers worldwide. Positive stop ensures tips always eject at the same light force and creates a strong seal in the same location every time. Currently, major drawbacks of AAVs is scaling up the manufacture of sufficient quantities for the treatment of large patient groups. The products you use, the products you need, the suppliers you trust for chromatography. © 2020 VWR International, LLC. The Polyplus® test is able to detect and quantify residual PEIpro® throughout the ATMP manufacturing process. The idea here is to use the assembly mechanism of a virus to display more commonly spike protein peptide on their surface. This means that further administration will be required if additional gene expression is required. Designs include upholstered chairs and stools as well as urethane chairs and stools and polypropylene chairs for real-world applications. Transient protein expression allows generation of high protein amounts in a short amount of time and can offer a reliable alternative to production of stable cell lines for proof of concept studies and tools validation. 850 bd Sébastien Brant 67400 Illkirch FRANCE, 1251 Ave of the Americas 3rd Fl, New York NY 10020 USA. Polyplus-transfection® SA is the leading biotechnology company that supports Gene and Cell therapy, biologics manufacturing and life science research with innovative nucleic acid transfection solutions. Rinse-free and biodegradable. “ATMPs and gene therapies are moving through late-stage trials and to commercialization at an exponential rate. There are three methods to transfect guide RNA and express Cas9 protein in mammalian cells:  DNA-, RNA- or ribonucleoprotein-based delivery. Non-viral in vivo delivery reagents are the most powerful alternative to viral vectors for nucleic acid delivery. As our customers’ needs have evolved, so have our capabilities. Conjugation of both proteins composes an excellent strategy for antigen presentation and immunogenicity. Alternatives may be available by searching with the VWR Catalog Number listed above. The difference in lentiviral vectors however is that they possess the capability to integrate their genome into non-dividing cells. “Now is a natural time to transition leadership as Polyplus enters its next chapter and Mario is the ideal person to continue to grow Polyplus’ core business and deliver long-term value. Already more than 90 vaccines are currently under development using 4 main strategies: virus-based vaccines, nucleic acid-based vaccines, protein-based vaccines and viral vector vaccines. FectoVIR®-AAV: for Recombinant AAV virus production in suspension cells. These viral vectors first need to be produced in mammalian cells. Based on the Science Park close to Strasbourg (France), Polyplus-transfection® offers an extensive and growing range of transfection reagents available worldwide. Researchers cloned the heavy and light chains of the variable domains of V2-glycan and V3-glycan bNAbs into the human IgG1 expression vector and expressed bispecific antibodies using FectoPRO® in suspension Expi293 cells. Transfection toolbox for spike protein vaccine strategies. Non-viral in vivo delivery is a safe method for delivery of nucleic acids in different organs of various animal models. In their recently published study, Alsoussi et al., 2020 proceeded to produce recombinant mAb after using the recombinant RDB to immunize mice. Kaku Y, Kuwata T, Gorny MK, Matsushita S.
