ELISA: yes (see remarks)
Immunogen Recombinant protein corresponding to residues near the carboxy terminus of rat Bassoon. (UniProt Id: O88778)
Reactivity Reacts with: rat (O88778), mouse (O88737).
No signal: chicken.
Other species not tested yet.
Specificity Specific for Bassoon
Remarks

WB: Due to its large size, bassoon 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.
ExM: This antibody has been successfully used for the epitope-preserving magnified analysis of the proteome (eMAP) expansion microscopy method (Park et al. 2021. PMID: 34767453).
ELISA: Suitable as detector antibody for sandwich-ELISA with cat. no. 141 021 or 141 011 as capture antibody. The ELISA-protocol for membrane proteins is recommended.

Background

Bassoon is a large protein which consists of an N-terminal Zn2+ finger and several piccolo-bassoon homology domains (PBH-domains). It is generally found together with piccolo, a related huge multi-domain protein of the CAZ (cytoskeletal matrix assembled at active zones).
Bassoon was suggested to be a scaffolding element of the presynapse but deletion experiments in mice have shown that bassoon is also involved in synaptic vesicle cycling. Probably bassoon interacts with other protein factors via its Zn2+ domain but the potential partners have not been determined yet.
