Expression System
HEK293 cells
Tag
N-terminal his-tag
Purification
His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC)
Purity
>90%
Purity Determined By
SDS-PAGE under reducing conditions and visualized by Coomassie blue staining
Molecular Weight (kDa)
Recombinant protein product has a calculated molecular mass of ∼22 kDa. Due to the abundant glycosylation, it migrates as approximately ∼25-35 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. After deglycosylation under native and denature conditions, the protein presented as one major ∼22 kDa band. See deglycosylation analysis image below.

Formulation
Supplied as a 0.2 µm filtered solution in PBS (pH 7.4)
Concentration (lot specific)
Lot specific (see the label on the vial), determined by BCA protein assay
Endotoxin Level
< 0.5 EU per µg of the protein as determined by the LAL method
Research Area

Figure 1.Deglycosylation analysis of purified recombinant proteins. The same amount of purified proteins were untreated (Lane 2) or treated with protein deglycosylation enzymes under native (Lane 3) or reducing (Lane 4) conditions. Deglycosylation treatment resulted in a mobility shift of the protein to produce one reduced band at the expected size (˜25 kDa), thus indicating that the untreated recombinant protein (Lane 2, ˜30 kDa) was glycosylated. Lane 1: Protein standard ladder (kDa) Lane 2: Untreated protein Lane 3: Treated protein with deglycosylation enzymes under native conditions. Lane 4: Treated protein with deglycosylation enzymes under denature conditions. Lane 5: Deglycosylation enzymes only without target proteins.
Binding Function
Product binding ability was measured by ELISA. The immobilized recombinant SARS CoV-2 spike S1 subunit protein (Catalog #230-30161, coated at 2 µg/ml, 100 µl/well) was incubated with the serial diluted human basigin protein (Catalog #230-30181). The bound basigin protein was detected by anti-basigin antibody using ELISA. The calculated EC50 is 138.6±54.8 ng/ml.
