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.
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.
Form
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4
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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
3-7 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Activity
Measured by its binding ability in a functional ELISA. Immobilized Human SLC3A2 at 2 μg/ml can bind Anti-SLC3A2 recombinant antibody (CSB-RA021640MA1HU). The EC50 is 2.257-3.091 ng/mL.
Description
SLC3A2 forms the heavy chain of heterodimeric amino acid transporters and serves as a critical regulator of nutrient uptake in cancer cells, making it a valuable target for metabolic profiling and therapeutic development. This mammalian-expressed fragment spanning residues 206–630 demonstrates quantifiable antibody-binding activity with an EC50 of 2.257–3.091 ng/mL in functional ELISA, confirming that the extracellular domain retains native conformational epitopes suitable for antibody development, ELISA standardization, and ligand-binding assays. The protein meets the purity and endotoxin criteria typical for membrane transporter functional studies and drug-protein interaction screens, with greater than 90% purity by SDS-PAGE and less than 1.0 EU/μg endotoxin. Researchers investigating amino acid transport mechanisms, cancer metabolism, or developing anti-CD98 therapeutics will find this protein provides a suitable basis for binding kinetics measurements and structural characterization of transporter complexes.
