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 2B21 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects Synaptophysin. It targets an epitope within 86 amino acids from the C-terminal region. It does not react with human Synaptophysin.

Immunogen

GST/His-tagged recombinant fragment corresponding to 86 amino acids from the C-terminal region of rat Synaptophysin.

Application

Anti-Synaptophysin, clone 2B21 ZooMAb, Cat. No. ZRB1365, a recombinant Rabbit monoclonal antibody that targets Synaptophysin and is tested in Immunocytochemistry, and Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Synaptophysin in rat brain tissue lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Synaptophysin in rat brain tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Synaptophysin in PC12 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Synaptophysin (UniProt: P07825; also known as Major synaptic vesicle protein p38) is encoded by the Syp gene (Gene ID: 24804) in rat. Synaptophysin belongs to the synaptophysin/synaptobrevin family of proteins. It is one of the major glycoproteins present in presynaptic vesicles and in various neuroendocrine cells of both neuronal and epithelial phenotype. Its structure consists of a hexameric protein of four transmembrane spans with a short cytoplasmic amino- and a long carboxy-terminal tail. Both amino- and carboxy-terminals are exposed on the cytoplasmic surface of the synaptic vesicle membrane. The C-terminal domain of Synaptophysin is required for endocytosis during, but not after, cessation of sustained synaptic transmission. Synaptophysin is involved in organizing membrane components and may regulate endocytosis to ensure vesicle availability following sustained neuronal activity. It is also involved in the regulation of short-term and long-term synaptic plasticity. Syp/neurons display functional deficiencies and slower recovery of the recycling synaptic vesicle pool. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Kwon, SE., and Chapman, ER (2011). Neuron. 70(5); 847- 854).

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

30 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

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.

Digital light processing bioprinting favors biofabrication of tissues with improved structural complexity. However, soft-tissue fabrication with this method remains a challenge to balance the physical performances of the bioinks for high-fidelity bioprinting and suitable microenvironments for the encapsulated cells to
