Note: The complete
sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is
translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Protein Length
Full length protein
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.
Can insert into membranes and form chloride ion channels. Channel activity depends on the pH. Membrane insertion seems to be redox-regulated and may occur only under oxydizing conditions. Modulates the activity of RYR2 and inhibits calcium influx.
