Custom and Bulk Reagents—Providing Quality and Performance at Exceptional Value

Founded in 2011 by a team of immunologists, researchers, and industry leaders, Tonbo Biosciences was conceived of a simple principle: provide products of equivalent performance and exceptional value.

“We’re able to provide high-performance, value-oriented products of the highest quality by aligning ourselves through disciplined and innovative science with our customers. This allows us to create a unique value-oriented and customer-focused company,” says Todd R. Nelson, Ph.D., founder of Tonbo Biosciences.

Tools for understanding the development, phenotype, and function of specific immune cell subsets are critical to the modern immunologist. Tonbo Biosciences provides a rapidly expanding line of trusted clones for flow cytometry (FCx-Pro™), low endotoxin antibodies for functional assays (In Vivo Ready™), and recombinant cytokines and growth factors for cell activation (RPx-Pro™). Reagents for cell viability (including Ghost Dyes™) plus flow cytometry support buffers and solutions round out the portfolio. Tonbo Biosciences guarantees all of its reagents to perform in accordance with industry standards, and we offer the most competitive pricing, creating exceptional value for our customers.

We currently offer over 1,000 products, most of which are available in convenient bulk sizes for consistency in long-term studies, as well as optimal value. During validation, these antibodies are benchmarked against matched clones sold by other leading brands for quality and staining concentration in order to provide our customers with equivalent or better performance.

We also offer custom fluorophore conjugation, high concentration and specialty buffer formulation, as well as antibody cocktail development services. Our experienced scientists specialize in manufacturing the highest quality custom reagents, ensuring optimal results in your protocols. All custom products are produced in our San Diego, CA, facility by our skilled manufacturing team.
