Abstract The emergence of numerous SARS-CoV-2 variants, characterized by mutations in the viral RNA genome and target proteins, has presented challenges for accurate COVID-19 diagnosis. To address this, we developed universal aptamer probes capable of binding to the spike proteins of SARS-CoV-2 variants, including highly mutated strains like Omicron. These aptamers were identified through protein-based SELEX using spike proteins from three key variants (D614G-substituted Wuhan-Hu-1, Delta, and Omicron) and virus-based SELEX, known as viro-SELEX. Leveraging these universal aptamers, we created a highly sensitive lateral flow assay (LFA) and an ultra-sensitive molecular diagnostic platform that integrates a novel rapid PCR technique, enabling fast and reliable detection across all SARS-CoV-2 variants.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
