Tag Info
N-terminal 10xHis-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Storage Condition
Store at -20°C, for extended storage, conserve at -20°C or -80°C.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
SNAREs, soluble N-ethylmaleimide-sensitive factor-attachment protein receptors, are essential proteins for fusion of cellular membranes. SNAREs localized on opposing membranes assemble to form a trans-SNARE complex, an extended, parallel four alpha-helical bundle that drives membrane fusion. VAMP8 is a SNARE involved in autophagy through the direct control of autophagosome membrane fusion with the lysososome membrane via its interaction with the STX17-SNAP29 binary t-SNARE complex. Also required for dense-granule secretion in platelets. Plays also a role in regulated enzyme secretion in pancreatic acinar cells. Involved in the abscission of the midbody during cell division, which leads to completely separate daughter cells. Involved in the homotypic fusion of early and late endosomes. Participates also in the activation of type I interferon antiviral response through a TRIM6-dependent mechanism.
