Recombinant Toxoplasma gondii Dense granule protein 3 (GRA3), partial

Direct host-parasite interaction occurs at the cytoplasmic faces of the parasitophorous vacuole membrane (PVM) and the host endoplasmic reticulum (ER) membrane via GRA3 and host CAMLG association. Direct insertion of GRA3 ER retrieval motif into the host ER membrane contributes to the host ER recruitment to the PVM.

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.

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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

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.
