Activation of protein kinase, such as JNK and Akt, plays
an important role in apoptosis and other physiological and
pathological processes. BioVision provides a novel
nonradioactive system for convenient measurement of JNK and
Akt activities. The JNK Activity Screening Kit is
used to screen JNK activity relatively quickly for large
numbers of samples. The assay utilizes a N-terminal c-Jun
fusion protein bead to selectively “pull down” JNK from cell
lysate. c-Jun phosphorylation is then measured using a
phospho-c-Jun specific antibody. The KinaseSTARTM
JNK or Akt Activity Assay Kit utilizes a JNK- (or Akt-)
specific antibody to immunoprecipitate JNK (or Akt) from
cell lysate. JNK- (or Akt-) specific activity is then
analyzed by Western blot analysis of the phosphorylation
levels of c-Jun (or GSK-3a)
using a phospho-c-Jun (or phospho-GSK-3a)
specific antibody. The kit specifically detects JNK (or Akt)
activity, other kinase activities would not be detected.
