Absolute Antibody specializes in antibody engineering and the recombinant production of antibodies in any format. Our IgXpress™ antibody expression platform uses serum-free mammalian transient expression as a faster, more affordable alternative to stable cell line generation, and we’ve used it to manufacture antibodies in any species, isotype or subtype, as well as novel formats such as multispecifics, fragments and Fc fusion proteins. Our Periodic Table of Antibodies illustrates the more than 140 different antibody formats we’ve produced to date, with our real-world expression experience informing the manufacturability score of each antibody.
We can start antibody engineering and expression from your electronic antibody sequence, hybridoma cell line or purified antibody protein. We typically begin with a milligram-scale pilot production run to determine expression levels and purification strategy before moving onto larger-scale production. All production occurs at our ISO 9001:2015-certified manufacturing facility.
Depending on your needs, we can provide a reliable outsourcing solution for engineered antibody production, or a true consultative partnership in which we provide antibody engineering recommendations throughout the process to help optimize your antibody candidate. Either way, your project will be supported by a dedicated team with deep experience in therapeutic antibody development. All our services are royalty-free and customizable to your project.
Our engineered antibody production services include isotype switching, bispecific and trispecific antibodies, antibody fragments, and more. We use a variety of antibody purification strategies to enable manufacturing success across such a wide range of formats, including a proprietary lectin-based purification system for our IgA, IgM and IgE antibodies. Each engineered antibody is different, and our pilot run will inform further and larger-scale production to ensure we deliver antibodies of the highest possible quality.
