Application Details

Restrictions: For Research Use only

Handling

Format: Lyophilized

Reconstitution: Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1 mg/mL for 500 μg or 1 mg lyophilized powder. Do not mix by vortex or vigorous shaking.

Buffer: Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 8 % saccharose is added as protectant before lyophilization.

Storage: -20 °C,-80 °C

Storage Comment: -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.

Expiry Date: 12 months

Target Details

Target: SARS-CoV-2 Spike S1

Target Type: Viral Protein

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.

Molecular Weight: 77.94 kDa. Due to glycosylation, the protein migrates to 110-120 kDa based on Bis-Tris PAGE result.
