Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B
Myosin is the major component of thick muscle filaments, and is a long asymmetric molecule
containing a globular head and a long tail. The molecule consists of two heavy chains each ~200,000 daltons, and four light chains each ~16,000-21,000 daltons. Activation of smooth
and cardiac muscle primarily involves pathways which increase calcium and myosin phosphorylation resulting in contraction. Myosin light chain phosphatase acts to regulate muscle
contraction by dephosphorylating activated myosin light chain. This antibody is specific for the phosphorylated form of myosin light chain. The selected peptide sequence used to generate the
polyclonal antibody is located near the amino terminal end of the polypeptide corresponding to the smooth/non-muscle form of myosin regulatory light chain found in cardiac myocytes in
addition to smooth and non-muscle cells. This sequence differs from that of the sarcomeric/cardiac form of myosin regulatory light chain that has a different sequence around the phosphorylation site. pS20 is also referred to as pS19.
Catalog #M9850-02
ApplicationsSuitable for use in ELISA and Western Blot. Other applications not tested.
