Permeabilisation with ~0.2% Triton (in PBS) is recommended
Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.
Involvement in disease
Defects in ACTA2 are the cause of aortic aneurysm familial thoracic type 6 (AAT6) [MIM:611788]. AATs are characterized by permanent dilation of the thoracic aorta usually due to degenerative changes in the aortic wall. They are primarily associated with a characteristic histologic appearance known as 'medial necrosis' or 'Erdheim cystic medial necrosis' in which there is degeneration and fragmentation of elastic fibers, loss of smooth muscle cells, and an accumulation of basophilic ground substance.

ab21027 staining alpha smooth muscle Actin in mouse femoral artery by Immunohistochemistry (PFA perfusion fixed frozen sections.) Tissue was fixed in formaldehyde, permeabilized using 0.1% Triton, blocked using 10% serum for 1 hour at 22°C and then incubated with ab21027 at a 1/300 dilution for 16 hours at 4 °C. The secondary used was an Alexa Fluor®488 rabbit anti-goat used at a 1/1000 dilution.

ab21027 staining alpha smooth muscle Actin in mouse pancreas by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 1% BSA for 3 hours at RT; antigen retrieval was by heat mediation in a citrate buffer pH6. Samples were incubated with primary antibody (1/100) for 16 hours. An Alexa Fluor® 647 donkey anti-goat IgG polyclonal (1/500) was used as the secondary antibody..
