ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 2I2 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Protein Bassoon (BSN). It targets an epitope within the C-terminal half.

Immunogen

GST/His-tagged recombinant fragment corresponding to 150 amino acids from the C-terminal half of human Protein Bassoon (BSN).

Application

Quality Control Testing

Evaluated by Western Blotting in U251 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected BSN in U251 cell lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected BSN in PC12 cell lysate.

Affinity Binding Assay: A representative lot of this antibody bound BSN peptide with a KD of 1.6 x 10-7 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected BSN in human cerebral cortex and human retina tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected BSN in E18 Rat hippocampal neurons.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-BSN, clone 2I2 ZooMAb®, Cat. No. ZRB1779, is a rabbit recombinant monoclonal antibody that specifically targets Protein Bassoon (BSN) and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry, and Western Blotting.

Target description

Protein bassoon (UniProt: Q9UPA5; also known as Zinc finger protein 231, BSN) is encoded by the BSN (also known as KIAA0434, ZNF231) gene (Gene ID: 8927) in human. BSN is a multi-domain peripheral membrane protein that is exclusively expressed in brain. It serves as a scaffold protein of the presynaptic cytomatrix at the active zone, the region in the synapse where neurotransmitter is released. At the presynaptic active zone, it regulates the spatial organization of synaptic vesicle cluster, the protein complexes that execute membrane fusion and compensatory endocytosis. It promotes vesicular replenishment and, consequently, a large standing pool of readily releasable synaptic vesicles at the endbulb synapse. BSN are transported on Golgi-derived membranous organelles, called Piccolo-Bassoon transport vesicles (PTVs), from the neuronal soma to distal axonal locations, where they participate in assembling new synapses. It is known to mediate synapse to nucleus communication leading to reconfiguration of gene expression by associating with the transcriptional corepressor CTBP1 and by subsequently reducing the size of its pool available for nuclear import. Mutant mice deficient in functional Bassoon are reported to suffer from epileptic seizures and have dysfunctional hippocampal synapses. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
