About Bethyl Laboratories

About Bethyl Labs in Montgomery TexasBethyl Laboratories, Inc. has been dedicated to supporting scientific discovery through its qualified antibody products and custom polyclonal antibody services since its founding in 1972.

Currently, Bethyl’s portfolio consists of over 9,500 catalog products; offering over 8,200 primary antibodies targeting over 3,300 proteins and 1,300 secondary antibodies raised against immunoglobulins from over 25 species.

With over 45 years of experience, Bethyl is also a leading provider of custom polyclonal antibody production services. Bethyl offers complete packages from initial peptide synthesis to affinity purification of custom polyclonal antibodies from an antigen-specific immunosorbent. Most recently, our capabilities have expanded and we now offer contract recombinant rabbit monoclonal antibody partnerships.

Every antibody that Bethyl sells has been manufactured to exacting standards at its sole location in Montgomery, Texas, and has been validated in-house by Bethyl’s team of scientists. From the veterinary facilities to the development, production and validation labs, the entire Bethyl team focuses on delivering quality products.

What does it take for an antibody to pass Bethyl’s validation and quality control? In other words, what makes a really good antibody? First and foremost, an antibody must be shown to recognize the intended protein target. An antibody must also show high sensitivity with minimal cross-reactivity. To achieve these goals, Bethyl has devised a unique process for validating the specificity of its antibody products, which is critical to reproducibility of antibody-based experiments in life science. While many companies settle on using data from a single antibody, Bethyl tests with paired antibodies raised against distinct protein epitopes.

Validating an image for specificityOnly after an antibody has been validated for specificity in immunoprecipitation and/or Western blot is it then tested in additional applications such as immunohistochemistry, immunocytochemistry, ChIP, and proximity ligation assay.

Because of its rigorous validation process and high standards, Bethyl does not sell every antibody it makes. Bethyl serves to advance science by concentrating its resources on developing qualified antibodies, including many to emerging and underserved protein targets.
