PG9

PG9, or Protein G 9, refers to a specific variant or subclass of the Protein G family, which are bacterial proteins known for their ability to bind the Fc region of immunoglobulins (antibodies). This property makes PG9 useful in antibody research and diagnostics, as it can be employed to detect or purify antibodies across various species. Understanding PG9 is valuable in immunology and biotechnology, especially for developing assays or therapies involving antibody interactions.
