Descrizione

Descrizione generale

Riconosce un epitopo situato sulla parte terminale azotata della isoforma- β dell′actina. Marca specificamente-actina- β in una vasta gamma di tessuti e specie. Nella colorazione per immunofluorescenza di sezioni criogeniche ultrasottili di ventrigli di pollo, l′anticorpo marca i corpi densi, i canali longitudinali che connettono corpi densi consecutivi che sono anche occupati da desmina e la placca densa associata alla membrana. L′anticorpo non reagisce con muscolo adulto cardiaco o scheletrico (se si eccettuano tracce dovute a contaminazione del campione con cellule non appartenenti a muscoli) o con cellule che esprimono actina-β nella ameba Dictyostelium discoideum. L′epitopo riconosciuto dall′anticorpo è resistente ai processi di fissazione in formalina e di inclusione in paraffina. B5, methacarn, etanolo o soluzioni di ‘Bouin′ possono inoltre essere usati come fissativi. L′anticorpo può essere impiegato come sonda per actinaβcome un controllo interno nei metodi a immunoblotting.

Actin is a highly conserved protein that is a major component of both the cytoskeletal and contractile structures in all cell types. It varies in amount, being related to the type of differentiation and to the functional state of cells and tissues. Actin can be found in two different forms of aggregation, the globular or the fibrillar state, and at least six distinct isoforms occur in vertebrates. The actins exhibit over 90% sequence homology, but each isoform has a unique NH2-terminal sequence. The isoforms are comprised of three α actins (skeletal, cardiac, smooth), one β actin (β-non-muscle) and two γ actins (γ smooth muscle and γ non-muscle). ACTB (actin β) gene codes for β-actin. It is a cytoskeletal housekeeping protein. It is present in the cytoplasm. The ACTB gene is located on human chromosome 7p22.1.
Monoclonal Anti-β-Actin (mouse IgG2a isotype) is derived from the AC-74 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.

Azioni biochim/fisiol

The two major cytoskeletal proteins implicated in cell motility are actin and myosin. Actin and myosin are constituents of many cell types and are involved in a myriad of cellular processes including locomotion, secretion, cytoplasmic streaming, phagocytosis, and cytokinesis. β-Actin (ACTB) modulates cell growth, migration and the G-actin pool. Mutations in ACTB leads to pleiotropic developmental disorder. It recognizes an epitope located on the N-terminal end of the β-isoform of actin. It specifically labels β-actin in a wide variety of tissues and species. In immunofluorescent staining of chicken gizzard ultrathin cryosections, the antibody labels the dense bodies, the longitudinal channels linking consecutive dense bodies that are also occupied by desmin and the membrane-associated dense plaque. The antibody does not react with adult cardiac or skeletal muscle (besides traces due to contamination of the sample with non-muscle cells) or with β-actin expressing cells in Dictyostelium discoideum amoeba. The epitope recognized by the antibody is resistant to formalin-fixation and paraffin-embedding. B5, methacarn, ethanol or Bouin′s solutions may be also used as fixatives. The antibody can be used as probes for β-actin as an internal control in immunoblotting.

Stato fisico

The product is provided as ascites fluid containing 0.1% sodium azide as a preservative.

Stoccaggio e stabilità

For continuous use, store at 2-8 °C for up to one month. For extended storage, solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify by centrifugation before use.
