Selection guide

  1. Antigen choice: Prioritize HA head/stem and NA for neutralization; NP/M1 for serology; M2e for universal vaccine; NS1 for immune evasion; PB1/PB2/PA for replication.
  2. Subtype/lineage: Match to A/H1N1, A/H3N2, B/Victoria, B/Yamagata; use conserved HA stem, M2e for cross-protection studies.
  3. Expression: Mammalian/insect for HA/NA to retain glycosylation/trimer; bacterial/mammalian for NP, M1, polymerase with activity validation.
  4. Assay: HAI for HA titer; microneutralization or pseudovirus for IC50; ELISA with 4PL/5PL; validate with CoA MRD and recovery.

FAQs

What is HA head vs. HA stem?

HA head (HA1): Dominant neutralizing site, prone to antigenic drift. HA stem (HA2): Conserved, enables broad-spectrum/cross-reactive antibody research.

How to choose A vs. B lineage?

Select based on study focus: A/H1N1, A/H3N2 (dominant in humans), B/Victoria, B/Yamagata (co-circulating). Use M2e, HA stem for universal vaccine candidates.

Can these be used in diagnostics?

All products are for Research Use Only (RUO) and not intended for diagnostic or therapeutic use.
