Piccolo antibody - 142 008

Piccolo is a large multi-domain protein of the presynaptic active zone
Rabbit monoclonal recombinant IgG
Cat. No.: 142 008
Amount: 100 µg
Price: $415.00
Cat. No. 142 008 100 µg purified recombinant IgG, lyophilized. Albumin and azide were added for stabilization. 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!

Remarks

This antibody is a chimeric antibody based on the monoclonal mouse antibody SY-294E1. 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.
WB: This antibody is less sensitive than the polyclonal product 142 113. We recommend 142 113 for westernblotting.  Due to its large size, Piccolo requires special gel-electrophoresis and Western blot protocols for visualization by immunoblotting. Excellent results can be obtained with the 4-12% TRIS-glycine gradient gels from Anamed or NuPAGE 3-8% TRIS-Acetate gradient gels from Invitrogen.

Background

Piccolo, also referred to as Aczonin, is a large protein which consists of an N-terminal Zn2+ finger, several piccolo-bassoon homology domains (PBH-domains) and C-terminal PDZ and C2 domains. In general it is found together with bassoon, a related huge multi-domain protein of the CAZ (cytoskeletal matrix assembled at active zones).
Piccolo is supposed to be a scaffolding protein for proteins involved in endo- and exocytosis of synaptic vesicles. Recently piccolo has been shown to interfere with clathrin mediated endocytosis by binding to the F-actin and dynamin binding protein Abp1.
