Each Signal Transduction AntibodyArray^TM contains 400 high quality antibodies against well-studied signaling proteins. The antibodies are arrayed onto a nitrocellulose membrane with a proprietary technique to completely retain the biological activities such as the binding of respective antigens.

Signal Transduction AntibodyArray^TM systems are generally used in the following applications:

• To screen novel protein-protein interactions. For example, when a scientist clones a new gene and he/she wishes to find out its interacting partners, an AntibodyArray^TM is the tool of choice.
• To find out changes in protein-protein interactions under different conditions, such as in different cell types, different developmental stages and different diseases.
• To examine changes in protein phosphorylations under different conditions.

Human, Mouse and Rat.

This array can be used in the study of human, mouse and rat systems. The majority of the antibodies on the array recognize human, mouse and rat proteins. Cross-reactivity to other species is not known.
