Form

Liquid or Lyophilized powder

Buffer

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage

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℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

Relevance

Evasion of NK cell killing. Blocks surface expression of PVR which is a ligand for NK cell-activating receptors. Binds human PVR in the endoplasmic reticulum and prevents its maturation and transport to the cell surface. Targets also the natural killer cell activating ligand NECTIN2 for proteasome-mediated degradation. Additionally promotes intracellular retention of TNFRSF10A/TRAIL-R1 and TNFRSF10B/TRAIL-R2 and thus down-regulates their cell surface expression.
