  • SARS-CoV-2
  • Form:
  • Liquid
  • Purification:
  • Peptide affinity purification
  • Isotype:
  • IgG
  • Recommend Usage:
  • ELISA
    Immunofluorescence (1 ug/mL)
    Immunohistochemistry (0.2 ug/mL)
    Western Blot (1 ug/mL)
    The optimal working dilution should be determined by the end user.
  • Storage Buffer:
  • In PBS (0.02% sodium azide).
  • Storage Instruction:
  • Store at 4°C for three months. For long term storage, store at -20°C.

  • Note:
  • This product contains sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.
  • Applications
  • Western Blot (Transfected lysate)
  • Western Blot (Transfected lysate)
  • Western Blot analysis of Lane 1: WT 293 cells and Lane 2: SARS-CoV-2 Spike overexpressed 293 cells. Loading: 15 ug per lane of 293 cell lysate. Antibodies: SARS-CoV-2 S polyclonal antibody (Cat # PAB31725) (1 ug/mL), 1h incubation at RT in 5% NFDM/TBST. Secondary: Goat antirabbit IgG HRP conjugate at 1:10000 dilution.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)
  • Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using SARS-CoV-2 S polyclonal antibody (Cat # PAB31725, 0.5 ug/mL). Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4°C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin. Strong spike protein signal was observed in macrophages and air epithelium of COVID-19 patient lung, but not in non-COVID-19 patient lung.
  • Immunofluorescence
  • Immunofluorescence
  • Immunofluorescent analysis of 4% paraformaldehydefixed 293T cells labeling SARS-CoV-2 (COVID-19) Spike with Cat # PAB31725 at 1 ug/mL, followed by goat anti-rabbit IgG secondary antibody at 1/500 dilution (green) and DAPI staining (blue).
  • Enzyme-linked Immunoabsorbent Assay
  • Enzyme-linked Immunoabsorbent Assay
  • A direct ELISA was performed using antigen or control peptide as coating antigen and this antibody as the capture antibody (1 ug/mL). Secondary: Goat anti-rabbit igG HRP conjugate at 1:20000 dilution. Detection range is from 0.5 to 1000 ng/mL.
