	α-Actin, skeletal and muscle (5C5)	Sigma Aldrich	monoclonal IgM	Mouse (liquid, ascites, azide)	-	Bovine, Rabbit, Frog, Snake, Sheep, Human, Guinea Pig, Rat	immunogen = rabbit striated muscle actin	specific for the single isoform of α-skeletal and α-cardiac muscle actins	-
	α-Actin, smooth muscle (1A4)	Sigma Aldrich	monoclonal IgG2a	Mouse (liquid, Tris, MgCl2, azide, glycerol, BSA, purified)	-	Bovine, Dog, Goat, Rabbit, Chicken, Frog, Snake, Sheep, Human, Guinea Pig, Mouse, Rat	immunogen = N-terminal synthetic decapeptide of α-smooth muscle actin	specific for the single isoform of α-smooth muscle actin (also known as anti-α-Sm-1)	-
	α-Actin, smooth muscle (1A4)	Sigma Aldrich	monoclonal IgG2a	Mouse (liquid, ascites, azide)	-	Bovine, Dog, Goat, Rabbit, Chicken, Frog, Snake, Sheep, Human, Guinea Pig, Mouse, Rat	immunogen = N-terminal synthetic decapeptide of α-smooth muscle actin	specific for the single isoform of α-smooth muscle actin (also known as anti-α-Sm-1)	-
	α-Actin, smooth muscle, FITC (1A4)	Sigma Aldrich	monoclonal IgG2a	Mouse (liquid, PBS, BSA, azide, purified, conj. FITC)	-	Bovine, Dog, Goat, Rabbit, Chicken, Frog, Snake, Sheep, Human, Guinea Pig, Mouse, Rat	immunogen = N-terminal synthetic decapeptide of α-smooth muscle actin	specific for the single isoform of α-smooth muscle actin (also known as anti-α-Sm-1)	-
	Actin	DSHB U. Iowa	monoclonal IgM	Mouse	-	Chicken, Various species, Rat	immunogen = cytoskeletal proteins from chicken gizzards	reacts with ~43kDa actin	-
	Actin (10A5)	Chemicon and Upstate are Millipore	monoclonal IgM	Mouse (liquid, ascites, azide)	-	Human	immunogen = human actin	recognizes actin	-
	Actin (420-8)	Chemicon and Upstate are Millipore	monoclonal IgM	Mouse (liquid, PBS, supernatant, azide)	-	Human	immunogen = chicken back muscle actin bound to KLH	recognizes actin bundles in human fibroblasts and epithelial cells; not Lymphoid cells	-
