AHP1117 specifically recognises the heavy chain of myosin II found in vertebrate smooth muscle, a non-striated muscle present in the walls of hollow organs, the vasculature, the respiratory and gastrointestinal tracts, uterus, bladder and eye.
The structure of myosin II is fundamentally the same in all muscle types and consists of two heavy chains, each bound by 2 distinct, essential and regulatory light chains. The globular motor domain located at the N-terminal domain of the heavy chains, catalyzes ATP hydrolysis and interacts with actin, whilst the heptad repeat sequences of the heavy chain tail domains promote dimerization, forming an alpha-helical coiled coil at the C-terminal domain.
This antibody does not cross-react with myosin of skeletal or non-muscle origin and can be used to specifically stain cultured smooth muscle cells and identify vascular and other smooth muscle types in tissue sections.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
AHP1117 recognizes a band of approximately 200kDa in Western blotting analysis of differentiating smooth muscle cell culture lysates, seeMargaritiet al.for details. Loading controls:
Rat anti tubulin α,MCA77.
Storage
Store at -20oC only.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
12 months from date of despatch.
Antiserum Preparation
Antisera to bovine smooth muscle myosin II were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG prepared by ion exchange chromatography.
