Creative Biolabs has been devoted for the development of protein microarray-based kits, in which large numbers of proteins can be tracked in parallel. We also offer other ELISA kits for specific detection of disease-related proteins. Our professional team is optimized to help you with high-quality and cost-effective testing service to make your project a success.
How does it work?
Protein microarray is a high-throughput method for tracking protein interactions and activities, determining their function, and determining function on a large scale. The chip consists of a carrier surface such as a glass slide, nitrocellulose membrane, bead or microtiter plate, to which the capture protein array is bound. Probe molecules that are usually labeled with fluorescent dyes are added to the array. Any reaction between the probe and the immobilized protein emits a fluorescent signal and is read by a laser scanner. Protein microarrays are fast, automated, economical and highly sensitive, consuming small quantities of samples and reagents. The high-throughput technology behind protein microarrays is relatively easy to develop because it is based on technology developed for DNA microarrays, which have become the most widely used microarray. Protein array detection methods must provide a high signal and low background:

Protein Microarray Based Kits for IVD Development
Creative Biolabs has been devoted for the development of protein microarray-based kits, in which large numbers of proteins can be tracked in parallel. In vitro diagnostics includes detection of antigens and antibodies in blood samples; serum analysis to discover new disease biomarkers; monitoring of disease states and treatment responses in individualized diseases; monitoring of the environment and food. Digital bioassay is an example of diagnostics using protein microarrays. In this technique, a microwell array on a glass/polymer chip is seeded with magnetic beads (coated with fluorescently labeled antibodies), subjected to targeted antigens, and then characterized by microscopic counting of fluorescent wells. A cost-effective fabrication platform for the use of such microwell arrays (using OSTE polymers) have been demonstrated and biometric model systems have been successfully characterized.
Creative Biolabs is a world leader in the development of ELISA based kits and now offers protein microarray-based kits for specific detection of disease-related proteins. If you are interested in our ELISA kits development, please feel free to contact us for more details.
