Lentivirus expresses the spike protein (S protein) of COVID-19 (SARS-CoV-2) coronavirus. It has the human codon optimization for high expression in mammalian cells, expressing the full length S-protein (click to see its Amino Acid sequence) ~140 kDa, with a poly-histidine tag at the C-terminus (6-His tag) which allow to purify the S-Protein via Ni NTA affinity column.
The target was expressed under enhanced CMV promoter. A RFP-Blasticidin fusion dual selection marker under RSV promoter, allows to sort or select transduced cells via RFP fluorescent signal or via Blasticidin antibiotic. RFP signal provides a convenient, realtime monitoring the lentivirus performance. See Product Manual for details (.pdf).
This is the concentrated lentivirus, resuspended in PBS solution, for high transduction rate in hard-to-infected cell types.
Amount: 200ul, at 1 x 108 IFU/ml in PBS
