Immunoassays feature

Choose high-quality Invitrogen immunoassays for protein quantitation

Rely on our 30 years of experience manufacturing and supplying antibody-based, target-specific protein quantitation reagents, kits, and panels for life science research. These products, which are collectively called immunoassays, include matched antibody pairs, uncoated and coated-plate ELISA kits, and multiplexing assays for the Luminex platform. All are validated for reliability and specificity. Select from hundreds of ready-to-ship kits or configure and order a custom assay panel.

To find an exceptional assay for your needs, choose from popular immunoassay categories below or contact our field application specialists (FAS), who can answer your questions and provide you with individualized immunoassay support, including information about new immunoassay technologies.
