特異性
This phospho specific polyclonal antibody is specific for phosphorylated pS20 of human myosin light chain. Reactivity with non-phosphorylated human myosin light chain is less than 1% by ELISA. 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. BLAST search analysis was used to determine that the smooth and non-muscle forms of myosin regulatory light chain have identical sequences. Cross reactivity is expected.
Customers have seen variable performance with Xenopus laevis.

特記事項（精製）
This antibody was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross-adsorbed against the non-phosphorylated form of the immunizing peptide. -

機能
Myosin regulatory subunit that plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation. Implicated in cytokinesis, receptor capping, and cell locomotion. -
組織特異性
Smooth muscle tissues and in some, but not all, nonmuscle cells. -
配列類似性
Contains 3 EF-hand domains. -
翻訳後修飾
Phosphorylation increases the actin-activated myosin ATPase activity and thereby regulates the contractile activity. It is required to generate the driving force in the migration of the cells but not necessary for localization of myosin-2 at the leading edge. - Information by UniProt

Cells were cultured on intermediate adhesion strength surfaces and extracted with 4% PEG and 1% Triton X-100 in cytoskeleton stabilizing buffer. Cells were blocked with PBS-BT for 5 minutes, and then incubated with primary antibody diluted in PBS-BT. Cells were then fixed with 4% formaldehyde in PBS for 10 minutes.
