Technical Data
Actin, alpha, Smooth Muscle
Actin is a highly conserved skeletal protein which is in both muscle and nonmuscle cells. The mammalian tissues express at least 6 unique actin isotypes. Alpha isotype is found exclusively in muscle cells including alpha-skeletal, alpha-cardiac, and alpha and gamma smooth muscle actin. Beta and gamma nonmuscular actins have been observed in non-muscle cells.

Suitable for use in Immunofluorescence and Immunohistochemistry. Other applications have not been tested.

Recommended Dilutions:
Immunohistochemistry (Formalin/paraffin): 1:800 for 20 minutes at RT. Required for the immunohistochemical staining of formalin/paraffin tissues.
Optimal dilutions to be determined by the researcher.

Positive Control:
Smooth muscle or leiomyosarcoma


Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
