Phospho-MYL9 (Thr19/Ser20) Polyclonal antibody

• 

  WB analysis using 29504-1-AP

  Non-treated and Calyculin A treated HeLa cells were subjected to SDS PAGE followed by western blot with 29504-1-AP (Phospho-MYL9 (Thr19/Ser20) antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with GAPDH antibody as loading control.

  FC experiment of HeLa using 29504-1-AP

  1X10^6 HeLa cells untreated (dashed lines) or treated with λ phosphatase were intracellularly stained with 0.13 ug Phospho-MYL9 (Thr19/Ser20) Polyclonal antibody (29504-1-AP) and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2)(red), or 0.13 ug Rabbit IgG control Polyclonal antibody (30000-0-AP). Cells were fixed with 4% PFA and permeabilized with 90% MeOH.

Tested Applications

• Positive WB detected in: Calyculin A treated HeLa cells
• Positive FC (Intra) detected in: λ phosphatase treated HeLa cells

This antibody, also known as Thr18/Ser19, is the site where the initiator methionine is removed.

Recommended dilution

• Western Blot (WB): WB : 1:500-1:2000
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.13 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Myosin regulatory light polypeptide 9 (MYL9), also known as MLC2, belongs to the myosin regulatory subunits. It plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation at Thr19 and Ser20. Implicated in cytokinesis, receptor capping, and cell locomotion (PMID:11942626, PMID:2526655). Some studies have demonstrated that MYL9 may play important roles in various human cancers. The expression and phosphorylation of MYL9 (Thr19/Ser20) may be increased in human breast (PMID: 22144583) and liver cancers (PMID: 18648664), while decreased in human colon (PMID: 22752057) and bladder cancers (PMID: 21139803). MYL9 was the only gene differentially expressed in the aged versus young injured arteries in the rat smooth muscle cell layers (PMID:22003410).
