V-DEL Platform
The V-DEL platform, led by our seasoned DEL experts, showcases high-quality DEL libraries and screening methods with high success rate. This platform integrates with Viva Biotech's comprehensive one-stop drug discovery solution, supported by advanced methodologies such as CADD + AIDD. It further synergizes with SBDD/FBDD and incorporates technologies like ASMS, SPR, X-Ray Crystallography, and Cryo-EM, offering a wide range of services. These include target protein production, customized DEL synthesis, affinity selection, follow-up synthesis, hit confirmation and assay development, medicinal chemistry as well as CDMO services. This holistic approach is designed to expedite the discovery of both FIC and BIC drugs.
High-purity, diverse protein
A top protein R&D platform with efficiency and scale.
Proprietary technologies for membrane protein expression and lipid nanodiscs preparation.
High-grade, differential V-DELs
High-quality V-DELs constructed with innovative strategies and on-DNA reactions.
Leveraging our med chem engine’s collection of large numbers of un-commercially available building blocks (~26,000)
High-quality, fast delivery
Supported by Viva Biotech’s med chem engine.
Shortened the timelines for both DEL synthesis and off-DNA re-synthesis.
Well-established confirmation process
Viva is a highly experienced provider of ASMS and SPR validation for DEL hits
Well-proven synergetic and holistic strategy
CADD+AI powered
Developed synergistic approaches, such as (DEL+FBDD/SBDD) and (DEL + FEP calculation)
Significantly boosts the success rate of DEL screening and its follow-up investigation.
Access to expertise across the organization
The below is the punch line, suggest to keep it as a whole.While you work with one platform at Viva, our entire team of experts with rich experience spanning nearly 20 platforms (including protein production, ASMS, SPR, X-ray crystallography, Cryo-EM, FBDD, SBDD, medicinal chemistry, ADME-PK, CADD, AIDD, and CDMO) is always accessible.
