A. Whole cell extracts (15 µg total protein) from HeLa cells mixed with the indicated amount of His-tagged recombinant SARS-CoV-2 S Protein S1 (Cat. No. 792906) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 µg/mL (1:500 dilution) purified anti-SARS-CoV-2 S Protein S1 recombinant antibody (clone AM004414) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-human IgG antibody at a 1:3000 dilution. Purified anti-His Tag antibody (clone J095G46) was used as a control antibody. Direct-Blot™ HRP anti-GAPDH antibody (Cat. No. 607904) was used as a loading control at a 1:25000 dilution (lower). Lane M: Molecular weight marker.

    Recombinant SARS-CoV-2 S Protein S1 (Cat. No. 792904) coated onto Nunc™ Maxisorp™ ELISA Plates (Cat. No. 423501) at 2 µg/mL and then incubated with a dilution series of purified anti-SARS-CoV-2 S Protein S1 recombinant antibody (clone AM004414). Bound antibodies were detected with biotinylated anti-human IgG secondary antibody followed by avidin-horseradish peroxidase and TMB substrate solution. Absorbance was measured at 450 nm.

Description

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a single- stranded RNA virus that belongs in a family of viruses known as coronaviruses.   SARS-CoV-2 infection, known as COVID-19, was declared a pandemic by WHO on March 11, 2020 and among other symptoms leads to respiratory infection, pulmonary failure which can be fatal. SARS-CoV-2 is structurally composed of 4 main proteins (e.g. spike glycoprotein, envelope glycoprotein, membrane glycoprotein and nucleocapsid protein) and several accessory proteins. The spike glycoprotein (S) is a transmembrane molecule that forms homotrimers on the surface of the virus and facilitates virulence through binding to angiotensin-converting enzyme 2 (ACE2) expressed on host cells. This protein is composed of two subunits S1 and S2. S1 subunit is responsible for binding to the host cell via ACE-2 receptor and S2 for fusion with the host cell.

This antibody is specific for the S1 subunit of SARS-CoV-2 and was derived, sequenced and expressed from patients that had recovered from COVID-19 infection.
