AlphaLISA ligand binding assays for measurement of human Immunoglobulin G subclasses in animal sera

This technical note describes AlphaLISA™ ligand binding assays for measuring human IgG subclasses (IgG1 and IgG4) in animal sera for pharmacokinetic applications. The assay relies on a homogeneous, no-wash format using donor and acceptor beads to quantify antibody levels across multiple species.

Key highlights

  • AlphaLISA assay for detecting human IgG1 and IgG4 in monkey, mouse, and rat sera.
  • Homogeneous, no-wash workflow based on donor and acceptor bead proximity for streamlined immunodetection.
  • Demonstrated performance with consistent spike recovery and dilutional linearity across serum matrices.
