Purified Mouse Anti-Tomosyn

Western blot analysis of tomosyn on a rat cerebrum lysate (left). Lane 1: 1:250, Lane 2: 1:500, Lane 3: 1:1000 dilution of the anti- tomosyn antibody.

Immunofluorescent staining of SK-N-SH cells (right). Cells were seeded in a 384 well collagen coated Microplates (Material # 353962) at ~ 8,000 cells per well.  After overnight incubation, cells were stained using the Triton X100 fix/perm protocol (see Recommended Assay Procedure; Bioimaging protocol link) and the anti- Tomosyn antibody.  The second step reagent was Alexa Fluor® 488 goat anti mouse Ig (Invitrogen)(pseudo colored green). Cell nuclei were counter stained with Hoechst 33342 (pseudo colored blue). The image was taken on a BD Pathway™  855 or 435 Bioimager System using a 20x objective and merged using the BD AttoVison ™ software. This antibody also stained SH-SY5Y, SK-N-SH, C6, U87 and U373 cells using both the Triton X100 and methanol fix/perm protocols (see Recommended Assay Procedure; Bioimaging protocol link).

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. 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.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.
  5. 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.

15/Tomosyn

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.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
