Target Name: SARS-CoV2 Spike S1 Protein, S1 Protein

Source: SARS-CoV-2 S protein (accession number QHD43416.1) S1 domain (Val16-Arg685) with C-terminus 8xHis tag is expressed in CHO cells.

Molecular Weight: The 683 amino acid protein has a predicted molecular weight of 76.5 kDa. The protein migrates at approximately 90-120 kDa on SDS-PAGE with DTT-reduced conditions.

 Purity: >95% based on SDS-PAGE

Formulation: PBS, 0.22 µm filtered

Vial Size: 25µg, 100µg

Protein Concentration: 25µg size is bottled at 0.2mg/mL concentration. 100 µg size is bottled at lot specific concentration.

Storage and Handling: Quick spin the vial after receiving. An unopened vial can be stored at 4°C for 2 weeks or at -20°C and below for six months. The protein can be further diluted to 0.1 mg/mL with 0.22 µm filtered PBS.  This stock solution should be aliquoted and stored at ≤ -70°C to minimize the freeze/thaw cycles. Carrier proteins such as FBS and BSA need to be added if further dilution is needed.
