The PSL Alliance

ICL is a trusted supplier of antibodies, ELISA kits, and protein reference standards to many of the world’s leading research institutions, pharmaceutical companies, and in vitro diagnostics (IVD) manufacturers. Established over 40 years ago in Oregon, USA, we develop and manufacture our products in-house using internal gold standard controls for validation, assuring our partners of consistent batch-to-batch performance, reliable long-term supply, and expert technical support from a team who knows our portfolio inside out.

Our growing product offering includes antibodies to a broad range of human, veterinary and infectious agent proteins, many of which are available from several host species and proven to work in multiple applica¬tions. These same antibodies form the basis of our ready-to-use sandwich ELISA kits and are complemented by an ex¬tensive selection of proteins for use as controls or reference standards. To streamline our partners’ research, we also offer core assay reagents like sera, streptavidin conjugates, and antibodies to common epitope tags.
