Target Name: SARS-CoV2 RBD, Spike RBD Protein, RBD Protein
Source: SARS-CoV-2 Spike protein (accession number QHD43416.1) RBD (Arg319-Phe541, N501Y) with C-terminus human IgG1-Fc tag is expressed in CHO cells.
Molecular Weight: The 462 amino acid protein has a predicted molecular weight of 52 kDa. The protein migrates at approximately 57 kDa on SDS-PAGE with DTT-reduced condition.
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.
