Anti-β Tubulin Antibody, clone AA2 ZooMAb^® Mouse Monoclonal

Tubulin beta chain (UniProt: Q2KJD0; also known as Tubulin beta-5 chain) is encoded by the TUBB gene (Gene ID: 615087) in bovine. Tubulin is the major constituent of microtubules (MTs). MTs are cytoskeletal filaments composed of α/β-tubulin heterodimers that self-assemble head-to-tail to form protofilaments and laterally to form a hollow tube. α/β heterodimers associate head-to-tail to form protofilaments running lengthwise along the microtubule wall with the beta-tubulin subunit facing the microtubule plus end conferring a structural polarity. Tubulin binds two moles of GTP, one at an exchangeable site on the β-chain and one at a non-exchangeable site on the α-chain. Tubulin dimers constantly polymerize and depolymerize, and MTs can undergo rapid cycles of assembly and disassembly. The first stage of MT formation, the nucleation phase, is slow. In the presence of Mg2+ and GTP, α and β tubulins join in an end-to-end manner to form protofilaments with alternating α and β subunits. GTP bound to β-tubulin is hydrolyzed to GDP during or immediately after polymerization. This weakens the binding affinity of tubulin for adjacent molecules and favors depolymerization that contributes to the dynamic behavior of MTs. MTs also undergo “treadmilling,” in which tubulin molecules bound to GDP are continually lost from the minus end and are replaced by the addition of GTP-bound tubulin molecules to the plus end of the same MT. Various post-translational modifications, including acetylation, polyglutamylation, polyglycylation, detyrosination, phosphorylation, and palmitoylation, can regulate the polymerization properties of tubulins and/or their interactions with microtubule associated proteins and motor proteins. β-Tubulin is reported to undergo phosphorylation on serine 172 by CDK1 during the cell cycle, from metaphase to telophase, but not in interphase. This phosphorylation inhibits tubulin incorporation into microtubules. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone AA2 is a ZooMAb^® mouse recombinant monoclonal antibody that specifically detects β Tubulin. It targets an epitope within 16 amino acids from the C-terminal region.

Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
