Biotinylated SARS-COV-2 Spike S1 Protein (COV-VM4S1B) Summary

Product Description

 Recombinant Biotinylated SARS-COV-2 Spike S1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Gln14-Arg683.

Product Background

 The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

Shipping, Reconstitution, & Storage

Form
 Lyophilized
Shipping
 Shipped at ambient temperature.
Formulation
 Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
 Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage
 -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
