Rabbit serum is used for the study of serum proteins and antibody-mediated immune responses. Rabbit serum provides a broad range of macromolecules, carrier proteins for lipids and trace elements, attachment and spreading factors, low molecular weight nutrients, hormones, and growth factors that promote cell growth and health. Goat anti-rabbit IgG (H+L) serum is a polyclonal antibody, which is generated by immunizing the goats using rabbit IgG whole molecule as an immunogen. Anti-Rabbit antibodies are used in research in the field of Cell Signalling, cellular biology, and signal transduction research. It is also used in immunoprecipitation techniques such as immunoelectrophoresis (IEP) and Ouchterlony to identify serum proteins, by the presence or absence of a particular protein.
