ELISA KIts & Reader

R&D Systems® ELISA Kits are the most trusted and widely published ELISAs on the market with a menu of 1,000 target analytes spanning 16 species. Our Quantikine Kits are complete, fully validated, ready-to-run immunoassay kits designed to measure proteins in diverse sample types.

Primary Antibody

Antibodies are essential tools for biomedical research as they allow researchers to identify specific proteins or molecules. Our catalog of over 425,000 antibodies from our R&D Systems™ and Novus Biologicals™ brands have been validated for specificity and reproducibility in over 25 species for more than 15 applications, ensuring that you will find one for your research needs

Secondary Antibody

Secondary antibodies recognize and bind to primary antibodies. They are used in many different experimental methods to help increase effectiveness of the platform. Our portfolio includes over 900 secondary antibodies for 26 reactive species.

Antibody Array

Our experienced architects provide personalized design solutions that turn your dreams into reality.

Luminex Assays

Discover and validate biomarker candidates with Luminex Discovery and Luminex High Performance multiplex immunoassays. Profile multiple analytes in one sample.

ELISPOT

This high throughput cytokine assay lets you enumerate cytokine secreting cells from up to 8 species without cellular expansion! Measure responses with frequencies lower than 1 cell per 100,000 cells. Choose from cytokines such as IFN gamma, IL-2, IL-6, TNF alpha and TGF beta.

Recombinant Proteins

Bio-Techne offers over 5,000 R&D Systems™ bioactive recombinant proteins spanning 35 species and multiple research areas. Our portfolio includes cytokines and growth factors, proteins for studying immuno-oncology targets, enzymes, Animal-Free and GMP-grade protein

GMP Protein

Highly consistent GMP proteins are key ancillary reagents for building your cell manufacturing program. We follow all relevant regulatory guidelines to ensure a consistent, safe, and traceable supply of animal-free bioactive proteins.

Stem Cell Products

Make the most of stem cells’ potential with consistent and thoroughly characterized cultures. Advance your research in developmental biology, disease mechanisms, drug discovery, and toxicology, as well as translational research for regenerative medicine therapies.

Cell Culture

Your unique cell cultures require a consistent foundation whether you are using classical or specialty media, serum, supplements, and matrices. Thorough cell characterization is also critical to determine if their phenotype is what you need for your particular application.
