Cytokine Families
Cytokines are signaling molecules secreted by cells that act as intercellular messengers to regulate a diverse array of biological processes. They are grouped into different families based on 1) sequence or structural similarities that may indicate a common evolutionary origin; 2) the composition of their receptor complexes; and/or 3) activation of similar signaling pathways and functional similarities.
Cytokines and growth factors are produced by a variety of different cell types and bind to specific cell surface receptors that induce responses such as cell proliferation, differentiation, activation, migration, survival, or death. As a result, these proteins affect nearly every biological process from immune responses and wound healing to disease pathogenesis and aging.
Common cytokine families include:
R&D Systems Rigorous In-House Testing Ensures the Performance and Consistency of Our Cytokine Research Reagents
R&D Systems has a rich history in the field of cytokine biology. We purified and sold our first recombinant cytokines in 1988. Since that time, we have continued to build our cytokine catalog and have used these rigorously tested proteins to produce high quality antibodies and the most trusted and widely published cytokine ELISA Kits on market.
Our ability to develop and manufacture over 95% of our proteins, antibodies, and immunoassays in-house is a core capability that sets us apart from the competition. It gives us remarkable control over reagent optimization during product development, and it allows us to implement quality tests that are unavailable to most reagent distributors. This ensures that we are providing our customers with the highest performing and most consistent reagents in the biomedical research market.
R&D Systems Product Development Workflow

R&D Systems Product Development Workflow and Rigorous In-House Testing Produces High Quality Cytokines, Antibodies, and Immunoassays. More than 95% of the 5,000 proteins offered by R&D Systems are manufactured in-house and undergo our rigorous quality testing to ensure high activity, purity, and lot-to-lot consistency. Using these high quality proteins as immunogens, we generate antibodies, making us one of the few antibody suppliers that still develops antibodies in-house. This in-house development, coupled with our strict application-focused antibody validation process and quality control specifications ensure exceptional antibody specificity and performance. R&D Systems' antibodies, along with our own proteins and diluents are then used to build R&D Systems ELISA Kits, the most trusted and widely published ELISA Kits on market. Our ELISA Kits are developed by testing several different monoclonal and polyclonal antibodies to determine which combination optimally couples for use in analyte detection. Selected antibodies are then carefully titered to ensure that the concentrations chosen will give the best possible results for the assay. Finally, the complete ELISA Kit is carefully tested to confirm that it meets our rigorous standards for specificity, recovery, linearity, and precision.
Cytokines for Immune Cell Culture
Cytokines are some of the most important components of cell cultures as they are necessary to maintain healthy cells, drive cell proliferation, and promote differentiation into specific cell lineages. R&D Systems rigorous in-house testing and quality control specifications ensure that our proteins will provide the highest levels of activity, purity, and lot-to-lot consistency, so that you can quickly standardize your protocols and minimize variability from one experiment to the next.
- Stringent quality control specifications for bioactivity, purity, and endotoxin levels
- Lot-to-lot consistency ensured by testing each new lot side-by-side with previous lots
- Large selection that includes over 5,000 bioactive, research-grade, Animal-free Preclinical, and GMP-grade proteins to address researchers’ needs from basic research to clinical manufacturing
Antibodies for Cytokine Blocking and Detection
Antibodies are essential tools for detecting and analyzing the functions of different cytokines. Our catalog includes thousands of antibodies validated for specificity and reproducibility in one or more of 15 applications, including blocking/neutralization, flow cytometry, immunocytochemistry, immunohistochemistry, Western blot, and Simple Western™.
- Extensive in-house validation and expert product support ensure performance
- Data images, citations, reviews, and a 100% satisfaction guarantee provide confidence that our antibodies will work in the applications and species designated
- Over 1,400 blocking/neutralizing antibodies validated with the same bioassays used to test the bioactivity of our proteins, ensuring they block/neutralize the appropriate cellular functions
- A wide assortment of primary antibodies, coupled with a selection of over 30 fluorescent labels, makes it easier than ever to find the exact antibody-fluorochrome combinations you need to directly detect your targets of interest, and provides the highest levels of flexibility for multiplex experiments
Immunoassays for Cytokine Secretion Analysis
For cytokine profiling and analysis, R&D Systems offers a wide selection of ELISA Kits. Our ELISA Kits are vertically integrated, meaning our proteins, antibodies, and diluents are manufactured in-house allowing us to maintain complete control over the quality of our products and ensure long-term supply stability.
Choose from a variety of different formats including our complete, ready-to-use Quantikine™ ELISA Kits, our 90-minute QuicKit™ ELISAs, and the more versatile DuoSet™ ELISA Development Systems that provide all the components necessary for a customer to develop their own working assay.
- Rigorous validation and quality control testing ensure the highest levels of performance and consistency
- Available controls with assigned data ranges guarantee performance
- Multiple formats provide flexibility and economical alternatives
