IHC staining of purified anti-SNAP-25 antibody (clone SP12) on formalin-fixed paraffin-embedded human brain tissue. Following antigen retrieval using Sodium Citrate H.I.E.R., the tissue was incubated with 5 µg/ml of the primary antibody for 60 minutes at room temperature. BioLegend´s Ultra-Streptavidin (USA) HRP kit (Multi-Species, DAB, Cat. No. 929901) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50 µm

Western blot of purified anti-SNAP-25 antibody (clone SP12). Lane 1: Molecular weight marker; Lane 2: 20 µg of SH-SY5Y cell lysate. The blot was incubated with 1 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.
Western blot of purified anti-SNAP-25 antibody (clone SP12). Lane 1: Molecular weight marker; Lane 2: 20 µg of human brain membrane lysate; Lane 3: 20 µg of mouse brain membrane lysate; Lane 4: 20 µg of rat brain membrane lysate. The blot was incubated with 0.2 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.
SNAP-25, also known as synaptosomal-associated protein 25, is a component of the trans-SNARE complex. It is a Q-SNARE protein anchored to the membrane on the cytosolic face, and does not contain a trans-membrane domain. The SNARE complex is involved in the vesicle fusion process. SNAP-25 is implicated in the inhibition of voltage-gated calcium channels, and has been shown to decrease calcium responsiveness in glutamatergic synapses.
This antibody was raised against a crude synaptic preparation from the post mortem human brain.
Formulation
Phosphate-buffered solution (no preservatives or carrier proteins).
Preparation
The antibody was purified by affinity chromatography.
Concentration
1 mg/ml
Storage & Handling
This antibody should be handled aseptically as it is free of preservatives such as Sodium Azide. Store this antibody undiluted between 2°C and 8°C. Please note the storage condition for this antibody has been changed from -20°C to between 2°C and 8°C. You can also check the vial label or CoA to find the proper storage conditions.
Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 5.0 - 10 µg/mL is suggested. For Western blotting, the suggested use of this reagent is 0.2 - 2.0 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.
