Introduction: Over the last few years, the clinical success of immune checkpoint inhibitors has increasingly drawn attention to cancer therapies that target the tumor microenvironment (TME). TME consists of various cell types that are embedded in the extracellular matrix (ECM), including immune cells, endothelial cells, and cancer associated fibroblasts, all of which play critical roles …Read More >

WuXi AppTec provides a comprehensive platform of advanced biophysical assays and structural biology services to accelerate lead optimization efforts focused on GPCRs and membrane proteins. Our capabilities include high-quality protein production across all major target classes and nanodisc reconstitution of membrane proteins for screening. We also offer established protocols for cryo-EM structure determination and assessment …Read More >

Introduction: As a therapeutic modality, oligonucleotides have a target abundance, persistent efficacy, high specificity, greater success rate and shorter R/D development period compared to other therapeutic approaches. Recently, significant achievements have been made in the discovery of oligonucleotide drugs. Numerous oligonucleotide drugs have been marketed. However, there are still many challenges, including limited delivery efficiency …Read More >

Powerful biophysical and structural biology tools enable the study of large numbers of fragments and are opening new possibilities in the treatment of various diseases. In this webinar, WuXi AppTec presents the results of a conventional and covalent fragment-based drug discovery screen, and our expert speaker discusses how orthogonal biophysical and structural methods enable the …Read More >

Viral vectors, such as AAV, have emerged as one of the most commonly used gene delivery vehicles. In this webinar, our speakers discuss how WuXi AppTec can help teams engineer and optimize viral vectors, and how best to utilize a range of in vitro and in vivo assays in our services platform to support the …Read More >

Learn about our semi-automated chromatography platform for parallel purification of high-quality therapeutic targets.  At PEGS Europe 2023, WuXi AppTec scientists described an automated workflow integrated with a serial size exclusion platform, resulting in a complete purification scheme for the rapid purification of high-quality proteins expressed in E. coli, insect cells, and mammalian cells.  This approach …Read More >

DNA-encoded libraries from WuXi AppTec were used in a “steered” screening against either inactive or active μ-opioid receptors in parallel, to find novel negative allosteric modulators of this receptor. The molecule discovered via DEL screening not only shows direct and effective in vitro and in vivo potency, but also helps elucidate the mechanism of negative allosteric modulation of GPCRs. This discovery …Read More >

The G12C mutation is one of the most frequent KRAS mutations in non–small cell lung cancer (NSCLC), and oncogenic RAS signaling has been shown to promote an immunosuppressive tumor microenvironment by upregulating PD-L1 expression.  At SITC 2023, WuXi AppTec scientists presented a poster showing that combination therapy of the KRAS G12C inhibitor AMG 510 with …Read More >

Introduction: Cancer is a major public health concern, and this disease is a leading cause of death worldwide. There are over 200 different types of cancer, and such complexity has slowed the rate of progress being made by researchers. Encouragingly, the emergence of immunotherapies, especially tumor vaccines, brings hope to cancer patients. Personalized tumor vaccines …Read More >
