  • 描述
    兔多克隆抗体to Myosin light chain (phospho S20)
  • 特异性
    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.

    Immunogen affinity purified
  • 纯化说明
    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.

IP 1/100.
IHC-P Use at an assay dependent concentration.

靶标

  • 功能
    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.
  • 组织特异性
    Smooth muscle tissues and in some, but not all, nonmuscle cells.
  • 序列相似性
    Contains 3 EF-hand domains.
  • 翻译后修饰
    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.

    Rabbit polyclonal to phospho Myosin Light Chain phospho Myosin Light Chain (Ser 20) (ab2480) used at a 1/5000 dilution to detect myosin light chain by Western blot. Either 13 ug (lanes 1-3) or 20 ug (lanes 4-7) of a mouse cardiac myocyte lysate was loaded on a 4-20% Criterion gel for SDS-PAGE.  Samples were either mock-treated or CLA treated:
    Lane 1 : untreated 45 min
    Lane 2 : CLA 50 nm 45 min
    Lane 3 : CLA 100 nm 45 min

  • IHC-P of ab2480 at 2.5 µg/ml staining both vascular and myometrial smooth muscle cells of the uterus.  The image shows localization of the antibody as the precipitated red signal, with a hematoxylin purple nuclear counterstain.

  • ab2480 staining Myosin light chain (phospho S20) in Xenopus laevis embryos by immunohistochemistry (PFA-perfusion fixed frozen tissue sections). The tissue sections were fixed in 2% TCA for 30 minutes and washed with PBST (PBS+0.3% TritonX 100) for 30 minutes. Samples were then blocked in 10% normal goat serum (NGS) for 1 hour at room temperature and incubated with the primary antibody. A Cy5 labelled Goat polyclonal to rabbit IgG was used as secondary.

    The arrows shows that depleting E-cadherin does not have any effect on the expression of apical pMLC.

    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.

Thank you for contacting us.

Are you looking for a specific light chain (i.e. 2 or 3)? We only have 2 other anti-myosin light chain antibodies as ab97891 and ab88726 but we don't have any WB images showing 2 bands for phopsho and unphosphory...

You are correct that Abcam has not specifically tested cross reactivity of ab2480 with skeletal muscle isoform MLC. This cross reactivity is predicted based on similarity of the immunogen sequence to skeletal muscle MLC. Likewise, ab2480 has ...
