Fast Activated Cell-based ELISA (FACE™) Kits provide a simple, sensitive method for detecting protein phosphorylation directly in the cell, without making extracts or performing electrophoresis and membrane blotting. These 96-well, high-throughput assays are available in both colorimetric and chemiluminescent formats for over 20 different targets (see list at right). For complete details, click the FACE™ Method tab below.
FACE JNK Kits provide 96 rxns each of 2 antibodies that enable you to monitor and compare the levels of both phosphorylated and total JNK (c-Jun N-terminal Kinase). The phospho-JNK antibody recognizes JNK1 only when phosphorylated at Thr183/Tyr185. The total-JNK antibody recognizes JNK1, JNK2 and JNK3 regardless of their phosphorylation states.

Figure 1: Colorimetric measurement of phosphorylated and total JNK.
The phospho-JNK antibody is specific for phosphorylated JNK and was raised against a phospho-peptide that corresponds to the sequence surrounding Thr183/Tyr185 of human JNK. It recognizes JNK1 only when phosphorylated at Thr183/Tyr185, and JNK2 and JNK3 only when phosphorylated at equivalent sites. The total-JNK antibody recognizes JNK1, JNK2 and JNK3 regardless of the phosphorylation state.
JNK (c-Jun N-terminal kinase), also called stress activated protein kinase (SAPK), is a member of the serine/threonine MAP kinase family. MAP kinase signaling cascades are critically important in translating the signals received at the plasma membrane into changes in cellular physiology and gene expression. JNK is activated in response to a variety of stimuli, including inflammatory cytokines, growth factors and cellular stresses such as UV-light. Because of JNK’s role in basic cellular processes such as inflammation and apoptosis, an understanding of the JNK signaling cascade should speed the development of therapeutics.
