Preparation and Storage
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- This antibody has been developed and certified for the bioimaging application. However, a routine bioimaging test is not performed on every lot. Researchers are encouraged to titrate the reagent for optimal performance.
- Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

Neuronal signal transmission and neurotransmitter release from the presynaptic nerve terminal is mediated by the synaptic vesicle cycle. Syntaxin plays a central role during vesicle docking and fusion through interactions with many vesicle components. During docking, vSNAREs (VAMP/synaptobrevin, synaptotagmin) on the synaptic vesicle and tSNAREs (SNAP-25, syntaxin) on the plasma membrane interact to form a 7S complex, which is essential to docking and fusion. Syntaxin associates with munc18/n-sec1 prior to and/or during the formation of the 7S complex. This interaction may inhibit syntaxin binding proteins (VAMP, SNAP-25) that facilitate vesicle docking or fusion. Tomosyn, a syntaxin binding protein, displaces munc18 from syntaxin-1 and forms a novel 10S complex with syntaxin-1, SNAP-25, and synaptogamin. There are two splice variants of tomosyn designated b-tomosyn and s-tomosyn, while the original is referred to as m-tomosyn. Although b-tomosyn is ubiquitously expressed, s-tomosyn and m-tomosyn are expressed primarily in brain.
