Recombinant Human Excitatory amino acid transporter 1 (SLC1A3), partial

Sodium-dependent, high-affinity amino acid transporter that mediates the uptake of L-glutamate and also L-aspartate and D-aspartate . Functions as a symporter that transports one amino acid molecule together with two or three Na (+) ions and one proton, in parallel with the counter-transport of one K (+) ion . Mediates Cl (-) flux that is not coupled to amino acid transport; this avoids the accumulation of negative charges due to aspartate and Na (+) symport . Plays a redundant role in the rapid removal of released glutamate from the synaptic cleft, which is essential for terminating the postsynaptic action of glutamate .

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 amino acid transporter, SLC1A3, is plasma membrane-localised in adipocytes and its activity is insensitive to insulin." Krycer J.R., Fazakerley D.J., Cater R.J., C Thomas K., Naghiloo S., Burchfield J.G., Humphrey S.J., Vandenberg R.J., Ryan R.M., James D.E. FEBS Lett. 591:322-330 (2017)

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.
