Scientific Data Images for SARS-CoV-2 Envelope Antibody (1044554)

SARS-CoV-2 Envelope in CHO Chinese hamster cell line transfected.

SARS-CoV-2 Envelope was detected in immersion fixed CHO Chinese hamster ovary cell line transfected (positive staining) and CHO Chinese hamster ovary cell line (non-transfected, negative staining) using Mouse Anti-SARS-CoV-2 Envelope Monoclonal Antibody (Catalog # MAB10925) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

SARS-CoV-2 Envelope in SARS-CoV-2 infected human lung.

SARS-CoV-2 Envelope was detected in immersion fixed paraffin-embedded sections of SARS-CoV-2 infected human lung using Mouse Anti-SARS-CoV-2 Envelope Monoclonal Antibody (Catalog # MAB10925) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to immunoreactive profiles scattered throughout the tissue. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

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).
