Article Title: Immunoassay Detection of SARS ‐ CoV ‐2 Using Monoclonal Antibody Binding to Viral Nucleocapsid Protein
doi: 10.1111/1751-7915.70117
Figure Lengend Snippet: Western blots showing the detection of disulfide reduced and heat denatured recombinant viral nucleocapsid proteins (NP) after electrophoresis (1 μg) with 4D4 (panel A) and 1H6 (panel B) MAb. Images were acquired at 30 s from nitrocellulose blots using a chemiluminescent substrate with HRP‐conjugated MAb (1 μg/mL) detection. A mixed standard was used to define protein migration by molecular weight (kDa). See recombinant NP details in Table [1–9]. Key: [1] SARS‐CoV‐2B 1.1.529 from E. coli . [2] SARS‐CoV‐2 B.1.1.529 from HEK 293. [3] SARS‐CoV‐2 Wuhan‐Hu‐1. [4] SARS‐CoV. [5] MERS‐CoV. [6] hCoV‐OC43. [7] hCoV‐HKU1. [8] hCoV‐NL63. [9] hCoV‐229E.
Article Snippet: Female Balb/cByJ mice (The Jackson Laboratory, ME) at 6 weeks of age were immunised every 10d, 4 times, by intraperitoneal inoculation with a 50 μL emulsion of 5 μg recombinant SARS‐CoV‐2 nucleocapsid protein (NP) Omicron B.1.1.529 variant from human embryonic kidney (HEK) cells (Acro Biosystems, DE) diluted in equal volume in TiterMax gold adjuvant (Sigma, MO).
