Institute or Center: 

This invention relates to synthetic immunoreactive peptides, which are portions of the M proteins of the most prevalent Group A Streptococcus (GAS) serotypes in the United States. These peptides may be useful in development of a flexible, multivalent GAS vaccine. They can be recognized by M type-specific antibodies and are capable of eliciting functional opsonic antibodies. Additionally, the peptides or isolated antibodies raised in response to the peptides may be useful for GAS diagnostics.

  • Group A streptococci (GAS) vaccine
  • GAS therapeutics and diagnostics
  • Lab tools for exploring GAS
  • Easily adaptable to kit form
  • Multivalent vaccine that can be tailored for protection against specific GAS serotypes affecting a particular population
