      Background InformationMicrotubules are constituent parts of the mitotic apparatus, cilia, flagella, and elements of the cytoskeleton. They consist principally of 2 soluble proteins, alpha- and beta-tubulin, each about 55 kDa in size.
      Antibodies against beta Tubulin are useful as loading controls for Western Blotting. However it should be noted that levels of beta Tubulin may not be stable in certain cells. For example, expression of tubulin in adipose tissue is very low (Spiegelman and Farmer, Cell, 1982, 29(1):53-60) and therefore beta Tubulin should not be used as loading control for these tissues.
      Product Information
      • Included Positive Antigen Control: Catalog # 12-301, non-stimulated A431 lysate. Add 2.5 µL of 2-mercaptoethanol/100 µL of lysate and boil for 5 minutes to reduce the preparation. Load 20 µg of reduced lysate per lane for minigels.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P07437 # Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain.
      SIZE: 444 amino acids; 49671 Da
      SUBUNIT: Dimer of alpha and beta chains.
      TISSUE SPECIFICITY: Ubiquitously expressed with highest levels in spleen, thymus and immature brain.
      DOMAIN: SwissProt: P07437 The highly acidic C-terminal region may bind cations such as calcium.
      SIMILARITY: Belongs to the tubulin family.
