Microtubules are essential parts in eukaryotic cell structures, transportation, and mitosis and consists mainly of 2 soluble protein subunits, alpha and beta tubulin. Beta-tubulin binds to alpha tubulin to form tubulin heterodimer which is post-translationally modified (1). The tubulin dimer complex binds to GTP and assembles onto the positive ends of microtubules. After incorporation into the microtubules, bound GTP is hydrolyzed by beta tubulin. The stability of the dimer in the microtubules is depended on presence of beta tubulin, where dimer with GTP bound beta-tubulin is stable to microtubule incorporation (2). Mutation on beta-tubulin has been linked to anti-cancer drug resistance in lung cancers (3).
Applications:
Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.
Recommended Dilution:
Western Blot: 1:10,000
Immunoprecipitation: 1:50
Immunohistochemistry: 1:100-1:250
Immunocytochemistry: 1:50-1:100
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
