High Quality Biochemical Assay Kits Provider
As a leading provider of high-performance, cost-effective bioassay kits for the life sciences industry, VKEY-BIO is primarily based on Luminescent and TR-FRET technology platforms. Our product lines include Luminescent, TR-FRET, Protein, and Consumables. Our mission is to contribute to the reduction of drug discovery costs by offering comprehensive and customized solutions for your research.
Luminescent
VKEY-BIO has independently developed the KeyTec® Luminescent platform, known for its high sensitivity and robust luminescence. Our products are often used in Reporter gene assays, Cell Viability Assays, and In Vivo Imaging.
TR-FRET
VKEY-BIO has independently developed the KeyTec® TR-FRET technology, which utilizes the stable energy donor (Solar Eu/Tb) and stable energy acceptor (LA/HX) in a time-resolved fluorescence resonance energy transfer system. TR-FRET is known for its ease of use, homogeneity (no wash), low background, wide range, and robustness. Our products are often used in Protein-Protein Interaction assays, cytokine detection, cAMP detection, Phosphoprotein detection, hybridoma screening and antibody concentration detection.
TRF
TR-FLISA (Time-Resolved Fluorescence Linked Immunosorbent Assay) is a variant of the ELISA technique that uses time-resolved fluorescent molecules instead of enzyme-catalyzed reactions. Compared to traditional ELISA, this method offers lower background signals, higher reproducibility, greater sensitivity, and is more time-efficient.
Proteins
VKEY-BIO has a dedicated Protein R&D department focused on developing various target proteins, followed by a stringent quality control (QC) program. These proteins exhibit high purity, stability, and activity (verified through ADP-GlO and TR-FRET technology detection methods). Our protein offerings span Kinases, Epigenetic factors, Phosphatases, DNA damage response proteins, Ubiquitin-Related proteins, Proteases, and other proteins.
Consumables
VKEY-BIO offers a total solution for high-throughput screening of candidate drugs, with our consumables product line, including microplates and seals. Our microplates ensure stable signals, low coefficient of variation (CV), and cost-effectiveness, with options available in 384 well and 1536 well formats. The KeyTec® Fluorescent High-Transparency Microplate Top Seals are designed for TR-FRET applications, allowing signal reading without seal removal. Additionally, the KeyTec® White Microplate Bottom Seals are designed for luminescent applications, providing higher signal and allowing observation of cell status before sealing.
Biochemical Assay Kits Applications
VKEY-BIO products can be used in life science research, aiming to be the key of your drug discovery. We have categorized our products into collections based on their applications, making it easier for you to access information according to your research interests. Furthermore, VKEY-BIO remains committed to continually improving our R&D and production capabilities to accelerate the deployment of applications in more research fields.
Kinase Solutions
VKEY-BIO offers over 200 kinase enzyme products validated through TR-FRET or ADP-Glo assay format, applied in kinase biochemical assay development. Simultaneously , we are developing kinase substrates and antibodies for TR-FRET assays. Additionally, our cell viability assay kits and reporter gene assay kits can aid you in developing cell-based assay research.
GPCR Solutions
VKEY-BIO offers over 300 GPCR cell lines, covering Gs, Gi, and Gq targets, as well as over 20 reporter gene cell lines, designed for GPCR research applications. Additionally, we provide cAMP detection kits and reporter gene assay kits to detect our cell lines.
CGT Solutions
Cell and gene therapy (CGT) involves utilizing cells or genetic material to treat diseases by correcting, replacing, or enhancing defective genes or cells within the body. VKEY-BIO offers a Dual Luciferase Detection Kit that can be used to assess the efficacy of gene editing or gene expression modulation techniques.
Immunology
Immunology is pivotal in drug development, especially in immunotherapy and vaccine research, targeting cancer and autoimmune diseases. VKEY-BIO offers cytokines detection kits for Immunology cell-based assay research.
Biologics Drug Discovery
Biologics drug discovery is centered around the development of therapeutic drugs derived from biological sources, including proteins, antibodies, and nucleic acids, to address a wide range of diseases. VKEY-BIO provides Hybridoma screening kits, antibodies detection kits, and cytokines detection kits to support biologics drug discovery research.
ADC Drug Discovery
ADC drug discovery focuses on developing targeted cancer therapies by combining monoclonal antibodies with potent cytotoxic drugs, with the aim of delivering the drug directly to cancer cells while minimizing harm to healthy tissue. VKEY-BIO offers a Cell Viability Detection Kit that can be used to assess the viability of cells treated with ADC drug interventions.
