SM2202P recognises the alpha subunit of Tubulin, specifically binding tyrosylated Tubulin (Tyr-Tubulin) (2). The epitope recognised by this antibody has been extensively studied and would appear to be a linear sequence requiring an aromatic residue at the C terminus, with the two adjacent amino acids being negatively charged (represented by Gly-Gly-Tyr in Tyr-Tubulin). The antibody has been used in epitope tagging procedures to detect proteins tagged with a C-terminal Gly-Gly-Phe epitope. These sequence requirements have been reported to result in some cross-reactivity with other proteins in certain circumstances, including E. coli rec A and oxidized Actin (5).
Purification
Affinity Chromatography on Protein G
Immunogen
Yeast Tubulin. Spleen cells from immunised LOU rats were fused with cells of the Y3.Ag.1.2.3 rat myeloma cell line.
TUBA1B
Reactivity: Human
WB, ELISA
Host: Mouse
Polyclonal
unconjugated
Application Notes
Immunohistochemistry on frozen sections. ELISA (1/100-1/1000, routinely tested in ELISA on Tubulin) (3). Immunoprecipitation. Radioimmunoassay. Clone YL1/2 has also been reported to work in western blotting (3). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
Tubulin is the major building block of microtubules. This intracellular cylindrical filamentous structure is present in almost all eukaryotic cells. Microtubules function as structural and mobile elements in mitosis, intracellular transport, flagellar movement and in the cytoskeleton. Tubulin is a heterodimer which consists of alpha tubulin and beta tubulin.Synonyms: Alpha-tubulin ubiquitous, Tubulin K-alpha-1, Tubulin alpha-1B chain, Tubulin alpha-ubiquitous chain
