Mol. Weight:30 kDa
Biological_Activity:?Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV S-RBD at 2 ?g/ml can bind Paguma larvata ACE2 (CSB-MP684964PAL), the EC50 is 5.056-7.559 ng/ml.?Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV S-RBD at 5 ?g/ml can bind human ACE2 (CSB-MP866317HU), the EC50 is 7.941-10.49 ng/ml.
Purity:Greater than 95% as determined by SDS-PAGE.
Endotoxin:Less than 1.0 EU/ug as determined by LAL method.
Form:Lyophilized powder
Buffer:Lyophilized from a 0.2 ?m filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
Reconstitution:We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.
