Mouse anti actin beta-cytoplasmic

Mouse anti actin beta-cytoplasmic

• Background: Among the six actin isoforms described in mammals, two are found in virtually all cells (β- and γ-cytoplasmic), two are detected in smooth muscle cells (α- and γ-smooth muscle) and two are present in striated muscles, one predominantly in skeletal (α-skeletal) and one in cardiac (α-cardiac) muscle cells. These actin isoforms differ slightly in their N-terminus, but the sequence of each of these actins is highly conserved in higher vertebRates. β- and γ-cytoplasmic actin play crucial roles during various key cellular processes. Whereas β-actin is preferentially localized in stress fibers, circular bundles and at cell-cell contacts, suggesting a role in cell attachment and contraction, γ-actin displays a more versatile organization, according to cell activities. In moving cells, γ-actin is mainly organized as a meshwork in cortical and lamellipodial structures, suggesting a role in cell motility. β- and γ-actin depleted fibroblasts exhibit distinct changes in motility compared with their controls, suggesting a specific role for each isoform in cell locomotion.
• CAS Number: 9007-83-4
• UniProt: P60709
• Host: Mouse
• Species Reactivity: Chicken, Human, Mouse, Rabbit, Rat, Swine, Zebrafish
• Isotype: IgG1
• Clone: 4C2
• Type: Primary Antibodies
• Source: 4C2 is a mouse monoclonal IgG1 antibody derived by fusion of NS0 mouse myeloma cells with spleen cells from a BALB/c mouse immunized with a peptide comprising the N-terminal nonapeptide of β-cytoplasmic actin with an acetylated N-terminus (Ac-DDDIAALVV-COOH) coupled to keyhole limpet hemocyanin through the cysteine residue. The antibody does not cross react with other actin isoforms.
• Applications: IHC (frozen), IHC (paraffin), WB, Flow Cytometry, ELISA
• Field of Research: Cytoskeleton, Stem cell research
• Assay Principle: 4C2 is useful for immunohistochemistry on frozen and paraffin-embedded tissues, immunoblotting, flow cytometry and ELISA. Optimal antibody dilution should be determined by titration; recommended range is 1:100 – 1:500 for immunohistochemistry with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent, and 1:1000 – 1:5000 for immunoblotting applications.
• Precautions: This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving Humans or animals. This product contains sodium azide. To prevent formation of toxic vapors, do not mix with strong acidic solutions. To prevent formation of potentially explosive metallic azides in metal plumbing, always wash into drain with copious quantities of water. This datasheet is as accurate as reasonably achievable, but Nordic-MUbio accepts no liability for any inaccuracies or omissions in this information.

• Shipping Conditions: Ambient Temperature
• Storage Conditions: The antibody is shipped at ambient temperature and may be stored at +4°C; For prolonged storage prepare appropriate aliquots and store at or below -20°C; Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2); Repeated thawing and freezing should be avoided; Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day; If a slight precipitation occurs upon storage, this should be removed by centrifugation; It will not affect the performance or the concentration of the product
