High quality, high purity and low endotoxin recombinant Recombinant SARS-COV-2 Spike RBD Protein (RPCB1386), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by Tris-Bis PAGE;≥ 95 % as determined by HPLC.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Reconstitution:
Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Recombinant SARS-COV-2 Spike RBD Protein was determined by Tris-Bis PAGE under reducing conditions.
The purity of SARS-COV-2 Spike RBD is greater than 95% as determined by SEC-HPLC.
