Antibodies and Proteins Information

Learn about methods and technologies for preparing and using antibodies and recombinant proteins in protein analysis techniques. Understand how specific primary and secondary antibodies are produced, screened, purified, and modified to enable their use in a myriad of protein detection (identification and measurement) applications.

Antibodies and proteins features

The Antibodies Learning Center organizes education information about antibodies. Antibody Methods reviews the steps of antibody production and purification. Cell Signaling Pathways provides visual maps of protein-mediated cellular processes, together with links to antibody search results.

Considerations for choosing a secondary antibody, including host and target species, targeted reactivity, purification, cross-adsorption, multiplexing, antibody class and subclass, whole antibodies vs. fragments, conjugates, and biotin-binding proteins.
