The non-muscle myosin IIA heavy chain (NMHC-IIA) phospho-regulation antibody sampler kit can be used to detect the level of phosphorylation of NMHC-IIA at Ser-1803, Ser-1916, and Ser-1943 relative to the total expression level of NMHC-IIA. The kit includes rabbit polyclonal phospho-specific antibodies to Ser-1803, Ser-1916, and Ser-1943, a rabbit polyclonal antibody to detect total NMHC-IIA, as well as a secondary regent for detection of antibodies in western blot, ELISA, or immunocytochemistry.

Western blot image of human A431 cells stimulated with calyculin A (100 nM, 30 min). The blots were untreated (lanes 1, 3 & 5) or treated with lambda phosphatase (lanes 2, 4 & 6), and probed with rabbit polyclonals Myosin IIA Heavy Chain (a.a. 1936-1950) (lanes 1 & 2), Myosin IIA Heavy Chain (Ser-1803), phospho-specific (lanes 3 & 4) or Myosin IIA Heavy Chain (Ser-1916) phospho-specific (lanes 5 & 6).

Immunocytochemical labeling of myosin IIA heavy chain phosphorylation relative to F-actin in chick fibroblasts. The cells were labeled with rabbit polyclonal Myosin IIA Heavy Chain (Ser-1943) antibody (MP3831), then detected using appropriate secondary antibody (Bottom, Red). This labeling is compared to F-actin staining (Bottom, Green) and to secondary only (Top). (Image provided by Dr. Gianluca Gallo at Drexel University).

Rabbit polyclonal antibodies are supplied in phosphate-buffered saline (PBS), 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide. The secondary reagents are supplied in the same buffer without azide. Store all at –20°C. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
