Species:MouseImmunogen:N-terminal decapeptide of alpha smooth muscle isoform of actin and conjugated to KLH.Clone:1A4Isotype:IgG2a, kappaSpecies Reactivity:Human, Baboon, Monkey, Cow, Pig, Sheep, Goat, Cat, Dog, Rabbit, Mouse, Rat, Guinea Pig and Chicken. Others not known.Positive Control:Blood vessels in all tissues, smooth muscle or leiomyosarcoma.Specificity:This MAb is highly specific to actin from smooth muscles. Its epitope lies in the first four N-terminal amino acids. This MAb does not stain cardiac or skeletal muscle; however, it does stain myofibroblasts and myoepithelial cells. In most cases of rhabdomyosarcoma, this antibody yields negative results whereas anti-muscle specific actin and myogenin are positive. Leiomyosarcomas are positive only with anti-muscle specific actin and anti-smooth muscle actin and are negative with anti-myogenin.Status:RUO PolyTek，抗兔聚合HRP已开发，具有成本效益，可提供最清洁，最一致的染色。该系统基于聚合的过氧化物酶标记，该标记从等式中消除了生物素，从而消除了背景染色的主要原因。
