Actins are highly conserved proteins expressed in all eucaryotic cells. Actin filaments form part of the cytoskeleton and play essential roles in regulating cell shape and movement. Six distinct actin isotypes have been identified in mammalian cells. Each is encoded by a separated gene and is expressed in a developmentally regulated and tissue-specific manner, alpha and beta cytoplasmic actins are expressed in a wide variety of cells; whereas, expression of alpha skeletal, alpha cardiac, alpha vascular, and gamma enteric actins are more restricted to specialized muscle cell type. Smooth muscle alpha actin is of further interest because it is one of a few genes whose expression is relatively restricted to vascular smooth muscle cells. Further more, expression of smooth muscle alpha actin is regulated by hormones, cell proliferation, and altered by pathological conditions including oncogenic transformation and atherosclerosis.
Applications:
Suitable for use in Flow Cytometry. Other applications not tested.
Recommended Dilutions:
Flow Cytometry: Neat. 10ul labels up to 1x10e6 cells.
Optimal dilutions to be determined by the researcher.
Hybridoma:
Fusion of a mouse myeloma with B cells obtained from a rat immunized with a synthetic decapeptide from the N-terminal of Alpha-Smooth Muscle Actin.
Storage and Stability:
Maybe stored at 4 degrees C before opening. DO NOT FREEZE! Stable for 12 months at 4 degrees C. Freezing R-Phycoerythrin (PE) conjugates will result in a substantial loss of activity. PE conjugates are sensitive to light.
