Summary Introduction

To explain: The zone of equivalence and its importance in immunoprecipitation reactions.

Introduction: The interaction between the antibodies and the antigens in appropriate proportions is the key to all immunoprecipitation reactions. The immunoprecipitation technique detects the presence of antibodies in a given sample. The reaction is considered positive when sample precipitation takes place by the formation of precipitin (antigen bounded antibody).
