Synaptic Systems - alpha-Tubulin

Cat. No.: 302 008

Amount: 100 µg

Price: $420.00

Cat. No. 302 008	100 µg purified recombinant IgG, lyophilized. For reconstitution add 100 µl H₂O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications	WB: 1 : 1000 up to 1 : 5000 (AP staining) gallery IP: not tested yet ICC: 1 : 500 (see remarks) gallery IHC: 1 : 500 gallery IHC-P: not tested yet
Clone	RbF2C
Subtype	IgG1 (κ light chain)
Immunogen	α-Tubulin purified from bovine brain
Reactivity	Reacts with: human, rat, mouse, cow. Other species not tested yet.
Specificity	Specific for α-tubulin
Remarks	This antibody is a chimeric antibody based on the monoclonal mouse antibody F2C. The constant regions of the heavy and light chains have been replaced with rabbit specific sequences. The antibody can therefore be used with standard anti-rabbit secondary reagents. The antibody has been expressed in mammalian cells and carries a Strep-tag^® at the C-terminus of the heavy chain. ICC: Methanol or PFA fixation

Background

Microtubules are involved in a wide variety of cellular activities ranging from mitosis and transport events to cell movement and the maintainance of cell shape.
Tubulin itself is a globular protein which consists of two polypeptides, α-tubulin and β-tubulin. α- and β-tubulin dimers are assembled to 13 protofilaments that form a microtubule of 22 nm diameter.

Assembled microtubules can be detyrosinated by a carboxypeptidaseS called vasohibins / SVBPs. Detyrosinated α-tubulin is referred to as Glu-α-tubulin and occurs for exemple in neurons. This reaction can be reverted by Tubulin tyrosine ligase (TTL) that ads a C-terminal tyrosin to Glu α-tubulin.
Another post-translational modification of α-tubulin is C-terminal polyglutamylation which is also characteristic for microtubules in neuronal cells and the mitotic spindle. A third variant of detyrosinated α-tubulin is Δ2-tubulin which lacks the C-terminal glutamic acid. It cannot be tyrosinated by TTL and is one of the dominant α-tubulin isoforms in neurons.
