Bio-techne and Cygnus Technologies Present Plex Hek 293 Hcp 3G Immunoassay

Bio-Techne Corporation | April 13, 2022

Bio_techne_and
Bio-Techne Corporation launched 3G assay for automated process impurity assessment on the EllaTM immunoassay platform ( NASDAQ: TECH ) and Cygnus Technologies, a division of Maravai LifeSciences ( NASDAQ: MRVI ).
In cell and gene therapy applications, the purification of viral particles to reduce host cell protein (HCP) contamination is an important part of the viral production workflow. To guarantee HCP impurity clearance is performed in compliance with regulatory criteria, accurate quantification throughout process phases is required.

The novel Simple Plex HEK 293 HCP 3G test uses a cartridge-based microfluidic design to deliver uniform and controlled assay conditions for HCP detection that is extremely accurate and reproducible. The test has a hands-free procedure and provides data in 90 minutes, providing pharmaceutical developers with a reliable and convenient tool for HCP impurity quantification. Simple Plex assays on the Ella platform, classic immunoassay methods, provide built-in calibration to reduce set-up time and user-dependent variability.

The gold standard in HEK 293 HCP impurity quantification is Cygnus Technologies' HEK 293 HCP ELISA Kit, 3G. With high-tech antibody affinity extraction and heavy spectrometry procedures, the kit's antibody was tested for reactivity to almost 3,000 distinct HCPs present in HEK 293 strains. The kit has been tested with various viral vector-based medicinal compounds and in-process samples, demonstrating that it possesses the specificity and sensitivity to detect HEK 293 HCP contaminants with the reproducibility needed to meet regulatory requirements. The Simple Plex HEK 293 HCP 3G assay uses the same HEK 293 HCP antibodies from market leader Cygnus Technologies, ensuring the Cygnus ELISA's extensive HCP detection coverage and industry-recognized specificity, as well as the automated Ella platform's workflow advantages.

We continue to enjoy the fruits of the Bio-Techne-Cygnus Technologies partnership as it provides the therapeutic development and manufacturing community an automated platform-based approach for HEK 293 host cell impurity testing, Fast and efficient process development and monitoring is crucial for biopharmaceutical companies providing a safe and efficacious product in a cost-effective manner."

MeMed raises $93M to accelerate commercialization of its host immune-response product portfolio

MeMed | January 10, 2022

MeMed, a leader in host response technologies, announces a $93 million private financing round, bringing total funding in the Company to over $200 million, including support from the U.S. Department of Defense and EU Commission. Funds will be used to scale up manufacturing, accelerate commercialization and expand MeMed’s pioneering host immune response product portfolio. MeMed’s technology suite decodes the body’s immune response within minutes, providing physicians with important patient management solutions that tackle key clinical dilemmas. The U.S. Food and Drug Administration (FDA) recently granted a landmark clearance for the use of the MeMed BV® test on the point-of-need platform MeMed Key®, to help healthcare providers distinguish between bacterial and viral infections in both children and adults. MeMed has also developed the MeMed COVID-19 Severity™ test for predicting severe outcomes in COVID-19 patients, which has been cleared for use in Europe. The latest financing brings together new and existing investors including Horizons Ventures, Shavit Capital, Social Capital, La Maison Partners, Touchwood Capital, Caesara Medical Holdings, Union Tech Ventures, ClaI Insurance, Phoenix Insurance, Poalim Equity and Western Technology Investment. “This new investment will enable MeMed to expand operations with a focus on the U.S. We are grateful to our investors for their support and will leverage the funds, the recent FDA clearance, and our growing network of partnerships to provide broad patient access to our technology, as well as expand our product portfolio of pioneering host response solutions.” Eran Eden, MeMed’s co-founder and CEO Patrick Zhang, Horizons Ventures, said: “We strongly believe that MeMed’s strategy of using host immune response technologies is a significant advance in the improvement of two major issues in healthcare today: the rise of antimicrobial resistance due to unnecessary prescription of antibiotics and effectively triaging patients infected with COVID-19. We look forward to playing a role in how MeMed, a category leader in this area, is transforming the way diseases are diagnosed and treated to improve patient healthcare across the globe.” About MeMed Our mission is to translate the immune system's complex signals into simple insights that transform the way diseases are diagnosed and treated, profoundly benefiting patients and society.

To Search for New Treatments Diseases, UW Oshkosh Partnered with Fauna Bio

Fauna Bio | April 01, 2022

A biotechnology business pioneering comparative, computational, and translational genomics, Fauna Bio, announced collaboration with the University of Wisconsin OshKosh to speed the translation of human treatments identified via research into extreme mammal adaption. Fauna Bio's sponsorship of UW Oshkosh with $500,000 expands the University's capability for biomedical partnerships and helps promote the University as a destination for academics exploring innovative animal models and building systems to expedite the translation to treatments. This partnership will advance the work already being done at UWO. It's an opportunity for our faculty to solidify their position as leaders in this field and to expand our educational opportunities for students." Provost and Vice Chancellor at UW Oshkosh, Prof. John Koker, Ph.D. It's well accepted that approaches to therapeutics discovery based on research using traditional animal models including mice and rats often fail because these animals do not accurately recapitulate human disease states. But there is enormous potential in studying animal models with natural disease resistance as an alternative strategy to treatment discovery, These efforts are historically under-supported and under-resourced despite the rise of available genomes and technologies to support translational science across a wide range of organisms. This partnership will create new educational opportunities to foster the next generation of scientists in regeneration and disease resistance from local scientific seminars to research and biotechnology internships for students." Fauna Bio's Director of Emerging Animal Models and a UWO adjunct biology professor, Benjamin Sajdak, Ph.D. Both Fauna Bio and UWO have established core expertise in the 13-lined ground squirrel (13-LGS), an animal that has exceptional resilience to human health concerns. Annually, the 13-LGS hibernates for about six months throughout the autumn and winter months. The 13-LGS will almost double their summer weight in preparation for hibernation, however despite their blood being very fatty and with restricted flow, they will survive many heart attacks and strokes. Both universities' researchers have made significant advances to genetics, biology, and neurology by researching this natural phenomena in 13-LGS. The proposed effort would sustain, maintain, and increase the present UWO 13-LGS colony while pursuing a common goal of finding the protective mammalian genes that enable the 13-LGS to escape health concerns during hibernation. The 13-LGS will remain in the possession of UWO. The Fauna Bio pipeline intends to identify these genes and create medicines capable of exerting a significant protective impact against human disease states. With the ability to prospectively design studies and collect samples at precise physiological time-points, the collaboration with UWO will enrich and enhance our own internal biobank datasets and no doubt lead to more novel insights on how species like the 13-lined ground squirrel resist developing human pathologies. This will help us develop more therapeutic programs and ultimately treat human diseases." Fauna Bio's Chief Scientific Officer, Katharine Grabek.
