CoV-2 Rec Spike, His, Flag (HEK) 1000ug

CoV-2 Rec Spike, His, Flag (HEK) 1000ug — Recombinant SARS‑CoV‑2 spike protein carrying His and Flag affinity tags, produced in HEK mammalian cells. Provided by STEMCELL Technologies.

• Format: mammalian‑expressed dual‑tagged spike (1000 µg) with mammalian glycosylation and folding—suitable for assays requiring native post‑translational modifications.
• Tags & utility: His and Flag tags facilitate purification and detection (affinity capture, Western blot, pull‑down assays).
• Applications: binding/neutralization studies, ELISA, SPR/BLI, antibody characterization and structural/biophysical analyses.
• Quality & handling: QC includes SDS‑PAGE and immunoblotting; supplied under cold chain. Suitable for in vitro assays with minimal endotoxin concerns relative to bacterial expression.
• Storage & reconstitution: store at ≤‑20 °C (preferably ‑80 °C). Reconstitute in an assay‑compatible buffer, aliquot and avoid repeated freeze–thaw.
