Immunogen alpha-SM1 (clone 1A4) is a mouse monoclonal IgG2a antibody derived by fusion of Sp 2/0 mouse myeloma cells with spleen cells from a BALB/c mouse immunized with a peptide comprising the first 10 amino acids of alpha-smooth muscle actin with an acetylated N-terminus coupled to keyhole limpet hemocyanin via the C-terminal cysteine (Ac-EEEDSTALVC).
Clone 1A4
Isotype IgG2a
Specificity The epitope recognized by alpha-SM1 is highly conserved. The antibody therefore cross-reacts with many species including protochordates, lower craniates and mammals (amongst others human, rat, chicken, goat, rabbit, mouse).
Purification Culture supernatant
Alternative Name alpha-smooth muscle actin (ACTG2 Antibody Abstract)
Background Among the six actin isoforms described in mammals, two are found in virtually all cells (betaˆ’ and gammaˆ’cytoplasmic), two are detected in smooth muscle cells (alphaˆ’ and gamma-smooth muscle) and two are present in striated muscles, one predominantly in skeletal (alpha-skeletal) and one in cardiac (alpha-cardiac) muscle cells. These actin isoforms differ slightly in their N-terminus and the sequences of each of them are perfectly conserved in higher vertebrates. Alpha-smooth muscle actin is abundant in vascular and visceral smooth muscle cells. In addition, it has also been shown to appear in stress fibers of fibroblastic cells during pathological situations involving contractile phenomena such as wound healing and fibrocontractive diseases.
Application Notes alpha-SM1 reacts exclusively with alpha-smooth muscle actin which is typical for vascular and visceral smooth muscle cells, but which is also present in myofibroblasts. The epitope that is recognized by alpha-SM1 is Ac-EEED. alpha-SM1 is useful for immunocytochemistry, immunohistochemistry on frozen and paraffin-embedded tissues, immunoblotting, immuno- electron microscopy and ELISA. Optimal antibody dilution should be determined by titration, recommended range is 1:10 - 1:100 for immunohistochemistry with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent, and 1:100 - 1:500 for immunoblotting applications.
