Our Abpromise guarantee covers the use of ab3451 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-Fr||Use at an assay dependent concentration.|
|IHC-FoFr||Use at an assay dependent concentration. PubMed: 23209433|
|IP||Use at an assay dependent concentration.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 67 kDa.Can be blocked with Munc18-1 peptide (ab4982).
By Western blot, this antibody detects an ~67 kDa protein representing Munc-18 from rat whole brain extract.

FunctionMay participate in the regulation of synaptic vesicle docking and fusion, possibly through interaction with GTP-binding proteins. Essential for neurotransmission and binds syntaxin, a component of the synaptic vesicle fusion machinery probably in a 1:1 ratio. Can interact with syntaxins 1, 2, and 3 but not syntaxin 4. May play a role in determining the specificity of intracellular fusion reactions.
Tissue specificityBrain and spinal cord. Highly enriched in axons.
Involvement in diseaseDefects in STXBP1 are the cause of epileptic encephalopathy early infantile type 4 (EIEE4) [MIM:612164]. Affected individuals have neonatal or infantile onset of seizures, suppression-burst pattern on EEG, profound mental retardation, and MRI evidence of hypomyelination.
Sequence similaritiesBelongs to the STXBP/unc-18/SEC1 family.
Cellular localizationCytoplasm. Membrane.

Anti-Munc18-1 antibody (ab3451) at 1/5000 dilution + Mouse hippocampal homogenate at 5 µg
Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97069) at 1/10000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Observed band size: 67 kDa why is the actual band size different from the predicted?
Exposure time: 1 minute
Western blot of Munc-18 in rat brain homogenate immunoprecipitated with ab3451.
1. Extract only.
2-4. 750 ug of extract immunoprecipitated with 1 ug, 5 ug, and 10 ug of ab3451, respectively.
ICC/IF image of ab3451 stained PC12 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab3451, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
Immunohistochemical analysis of PFA-perfusion fixed mouse brain tissue, staining Munc18-1 with ab3451.
Tissue was post-fixed in 4% paraformaldehyde overnight at 4°C. Sections were incubated in a blocking buffer of 0.3% Triton-X-100, 1% BSA and 10% NGS in PBS for 2 hours at room temperature, before incubating with primary antibody (1/100) for 2 days at 4°C. An AlexaFluor®-conjugated anti-rabbit IgG (1/1000) was used as the secondary antibody.
