Myristoylated Alanine-Rich C Kinase Substrate (MARCKS) is a major substrate for phosphorylation by protein kinase C (PKC). The phosphorylation of Ser152/156 can be used as a measure of PKC activation. Moreover, MARCKS is a member of a family of calmodulin binding proteins. Phosphorylation of Ser152/156 modulates the binding of MARCKS to calmodulin.

Immunolabeling of the 87kDa band in rat brain homogenate is blocked by the Ser152/156 phosphopeptide but not by the non-phosphopeptide. The antibody is purified by sequential chromatography on phospho- and non-phosphopeptide affinity columns. Antibody dilutions and tissue load should be based on tissue type and expected phosphorylation state. Initial recommended range of dilutions: 1:500 to 1:2000. Applications include Dot Blots (DB) and Western Blot (WB). Suitability for Immunohistochemistry (IHC) not yet determined. Human, mouse, rat, and Xenopus have 100% amino acid sequence identity with the antigen used to raise the antibody. When internally tested under ideal conditions the working dilutions were 1:1000 for DB and WB.

Affinity Purified

100 uL in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per mL BSA and 50% glycerol.

For long term storage –80°C is recommended, but shorter term storage at –20°C is also acceptable as aliquots may be taken without freeze/thawing due to the presence of 50% glycerol. Stable for one year.
