Recombinant Rabbit B (0, +) -type amino acid transporter 1 (SLC7A9), partial

Mediates the electrogenic exchange between cationic amino acids and neutral amino acids, with a stoichiometry of 1:1 . Has system b (0, +) -like activity with high affinity for extracellular cationic amino acids and L-cystine and lower affinity for intracellular neutral amino acids . Substrate exchange is driven by high concentration of intracellular neutral amino acids and the intracellular reduction of L-cystine to L-cysteine . Required for reabsorption of L-cystine and dibasic amino acids across the brush border membrane in renal proximal tubules.

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.
