Scientific Data Images for SARS-CoV-2 Envelope Antibody (1044526)

Detection of SARS-CoV-2 Envelope by Western Blot.

Western blot shows recombinant SARS-CoV-2 envelope. PVDF membrane was probed with 2 µg/mL of Mouse Anti-SARS-CoV-2 Envelope Monoclonal Antibody (Catalog # MAB10894) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for Envelope at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: Envelope

The SARS-CoV-2 Envelope protein is one of the four major structural proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19 (1). The envelope protein is the smallest of the four structural proteins, which also includes the membrane protein, spike protein, and nucleocapsid protein (1, 2). The envelope protein is synthesized as a 75 amino acid protein with a theoretical molecular weight of approximately 8.4 kDa (2, 3). Furthermore, the envelope protein of SARS-CoV-2 has 94.7% sequence identity and 97.4% sequence similarity to the envelope protein of SARS-CoV (2). Structurally, the envelope protein is a membrane protein with a N-terminal domain, an alpha-helical transmembrane domain, and a hydrophilic C-terminal domain (1,4). The envelope protein has multiple functions in viral replication including viral assembly, release, and pathogenesis (2,4). Additionally, the SARS-CoV-2 envelope protein has ion channel activity and functions as a viroporin with a role in virion trafficking (2, 4). Coronaviruses lacking the envelope protein are shown to have reduced viral titer and slowed or defective maturation, indicative of a role in virus production and growth (4).
