American Qualex - Manufacturing Quality and Excellence

American Qualex


It is our goal at American Qualex to offer the highest quality products to the research, healthcare, and biotechnology marketplace; saving the user time and money.


American Qualex was founded in July 1981.  The word “Qualex” was coined from “Quality and Excellence”.  Our initial intent was to:
Develop immunochemical manufacturing capability.
Market research products via private label.
Seek out new technology.

American Qualex currently manufactures over 2500 products used in immunology and molecular biology applications.


In 1981, a laboratory and separate animal facilities were built.  Soon thereafter, American Qualex proved its capability to produce high quality antibodies, conjugates and related research products.  In 1982, monoclonal capability was added.  In 1997, the capability to make recombinant proteins was added.

American Qualex is registered with the USDA and the FDA.  American Qualex currently produces antisera at several farm facilities which are maintained by long standing production agreements.  These farms are registered and operate under USDA and NIH Animal Welfare guidelines.

One of our featured services is kit component manufacturing.  Additional services include: antisera development, antibody production, purification, fragmentation, conjugation, coating of various matrices, peptide synthesis and recombinant protein production.  American Qualex produces small and large scale lots tailored to each customer’s specifications.

We take pride in providing quality products and lot–to–lot consistency.


American Qualex is a partner in several ventures to develop new products for research and diagnostics.  These include collaboration arrangements with universities and companies.


American Qualex has an active program to license products.  We are continually seeking to expand our product line by adding new products and technology.  Currently we have expanded our licensing to include manufacturing of antibodies and peptides that are validated by researchers at various institutions.


American Qualex actively markets its products and custom services through long standing private label agreements and OEM arrangements to biotech, diagnostic, and pharmaceutical companies worldwide.  Distributors have been established in most countries.

American Qualex has established product lines for specific marketing niches.  These product lines include: alphaQUEST Molecular Biology, STI - Signal Transduction Products, Cell2Cell Intracellular & Extracellular Products, and The Antibody Farm.

We currently exhibit at six national society meetings per year and present technical tutorials at two.  We attend over a dozen regional meetings a year.


American Qualex’s future efforts will be dedicated to expanding technical capabilities and enhancing business relationships by providing quality products that meet customer needs.
