Description
Source
DNA sequence encoding extracellular fragment[319-541] of COV2 Spike RBD domain [accession# QIC53204.1] variant (B.1.1.529/Omicron) ( G339D, S371L, S373P, S375F, K417N, N440K, G446S, S477N, T478K, E484A, Q493R, G496S, Q498R, N501Y, Y505H)including a C terminal His AVI tag was expressed in HEK cells.
Biotinylation
The COV2 RBD is thenbiotinylated in vitro at a single site using the AVItagTM biotinylation technology.
Molecular weight
Recombinant NCOV RBD B.1.1.529 encodes the NCOV spike glycoprotein RBD domain sequence . This molecule has a calculated mass of approximately 76kDa. Recombinant RBD migrates due to glycosylation as an approximately 120 kDa protein under reducing conditions in SDS-PAGE.
Activity
To be tested
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant COVID-19 Spike RBD was lyophilized from 0.2 µm filtered PBS solution pH7.4
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
Usage
This product is for research purposes only.It may not be used for therapeutics or diagnostic purposes.
