SpecificityThe specificity of this antibody has been confirmed by WB and IHC against the antigen. Human; mouse; rat;
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionA synthetic peptide of 10 amino acids corresponding to the N-terminus of alpha smooth muscle actin. This antibody reacts only with alpha smooth muscle actin and does not react with actin from striated muscle (alpha-sarcomeric) and myocardium (alpha-myocardial). It also does not react with beta and gamma actins.
Application DetailsImmunohistochemistry (IHC) and Western Blotting (WB). A concentration of 2.0 µg/mL is recommended for WB. Human smooth muscle actin has a predicted length of 377 residues and a MW of 42 kDa. A concentration of 0.1-0.5 µg/mL is recommended to detect alpha smooth muscle actin in formalin fixed and paraffin embedded tissues as well as formalin/acetone fixed tissues. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Reconstitution InstructionsSpin vial briefly before opening. Reconstitute in 1 mL of sterile-filtered PBS to achieve an antibody concentration of 100 µg/mL. Centrifuge to remove any insoluble material.
Storage InstructionsAt least 12 months after purchase at 2-8°C (lyophilized formulations). After reconstitution, aliquot and store at -20°C for a higher stability. Avoid freeze-thaw cycles.
Batch NumberPlease see item label.
Expiration Date12 months after date of receipt (unopened vial).
Scientific BackgroundActins are highly conserved proteins ubiquitously expressed in all eukaryotic cells. Three main groups of actin isoforms have been identified in vertebrates; alpha, beta and gamma. Alpha actins are found mainly in muscle tissues.
