Anti-UNC13B Antibody, clone 1B23 ZooMAb^® Rabbit Monoclonal

Protein unc-13 homolog B (UniProt: O14795; also known as Munc13-2, munc13) is encoded by the UNC13B (also known as UNC13) gene (Gene ID: 10497) in human. Protein plays a critical role in synaptic transmission and neurotransmitter release. It is involved in priming synaptic vesicles for exocytosis, acting as a key regulator in the docking and fusion of vesicles with the presynaptic membrane. Munc13-2/UNC13B interacts with various SNARE proteins, which are essential for the fusion of vesicles and the release of neurotransmitters into the synaptic cleft. It is highly expressed in the brain, especially in the cerebral cortex, where it influences neuronal excitability. It is also expressed in kidney cortical epithelial cells. Munc13-2 is localized to the presynaptic terminals of neurons and is also translocated to the plasma membrane. Munc13-2 is characterized by several distinct domains, including a C2 domain, a Munc13 homology domain, and a C1 domain. The C2 domain is involved in calcium binding, which is crucial for its role in synaptic transmission. The Munc13 homology domain is important for interactions with other proteins involved in exocytosis, while the C1 domain is associated with the binding of diacylglycerol, a lipid that plays a role in signaling pathways. Two isoforms of Munc13-2 have been described that are produced by alternative splicing. Alterations in Munc13-2 function or expression have been implicated in several neurological disorders. mutations in the Munc13-2 gene have been associated with epilepsy and other synaptic dysfunctions. Additionally, dysregulation of Munc13-2 has been linked to neurodegenerative diseases, such as Alzheimer s disease, where impaired neurotransmitter release may contribute to cognitive decline.

Clone 1B23 is a ZooMAb^® recombinant rabbit monoclonal antibody that specifically detects UNC13B. It targets an epitope within 23 amino acids from the N-terminal half.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

300 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.

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.
