SARS-CoV-2 Spike glycoprotein Receptor Binding Domain from mammalian HEK293 cells, frozen
Description: SARS-CoV-2 Spike glycoprotein Receptor Binding Domain (SCoV2-RBD) expressed as secreted protein in mammalian (human) HEK293 cells. The construct contains amino acids 319-529 of the Spike glycoprotein provided in UniProtKB sequence accession number: P0DTC2 (SPIKE_SARS2). Whole expression construct includes SCoV2-RBD (aa 319 – 529 of Spike glycoprotein) followed by introduced protease cleavage site and C-terminal His6-tag. SCoV2-RBD protein was purified from culture medium under native (non-denaturing) conditions using convenient chromatographic techniques. Then it was dialyzed against PBS, adjusted to 1.0 mg/ml concentration, filter-sterilized, aliquoted and frozen for storage.
Form: Frozen liquid in PBS (pH 7.4).
Storage: The product is shipped with dry ice (shipment costs: 130 € to Europe or 150 € to US). Store at -80°C for the long term. After thawing may be stored for short-term at 4°C (stable at least 2 weeks at this temperature). Avoid repeated freeze/thaw cycles.
Concentration: 1.0 mg/ml.
Purity: >98 % as determined by SDS-PAGE.
Image: SDS-PAGE showing SCoV2-RBD product 20-S2RBD-RHs-F at approximately 31-34 kDa (1, 3 and 5 μg/lane).
Applications (tested): ELISA, Western blot, SDS-PAGE.
