COVID-19 (SARS-CoV-2) Genome Sequencing

COVID-19 Genome Sequencing utilizes Next-Generation Sequencing (NGS) platforms to map the entire RNA genome of the SARS-CoV-2 virus. This high-throughput analysis represents the gold standard for tracking viral evolution, identifying emerging lineages (such as Alpha, Delta, Omicron, and their subvariants), and assessing potential immune evasion or altered transmissibility.

Key Features & Advantages

1. Whole Genome Coverage: Completely sequences the ~30,000 base pair RNA genome of SARS-CoV-2 without targeted gaps.
2. Lineage & Variant Identification: Accurately classifies Variants of Concern (VOCs) and Variants of Interest (VOIs) according to WHO and CDC guidelines.
3. Spike (S) Protein Mutation Profiling: Detects key amino acid alterations within the Spike protein to evaluate efficacy against neutralizing antibodies and therapeutics.
4. Phylogenetic Tracking: Maps transmission chains, community spread dynamics, and evolutionary divergence through robust phylogenetic tree reconstruction.
