Examples

• The laboratory identified several precipitinogens in the patient's serum sample.
• Precipitinogens are essential markers used in immunological testing and diagnosis.
• The reaction between precipitinogens and their corresponding antibodies produces a visible cloudiness.
• Researchers studied how different precipitinogens interact with antisera in the test tube.
• These precipitinogens are commonly detected using precipitation reactions in clinical immunology.
