Immunochemistry: Principles, Methods, and Applications

Preface Immunochemistry lies at the intersection of molecular immunology, analytical chemistry, biophysics, and clinical diagnostics. This book presents a comprehensive and quantitative framework for understanding antigen-antibody interactions, assay engineering, and translational diagnostic applications. It is designed for graduate students, laboratory professionals, and researchers in biomedical sciences.
Immunochemistry is the discipline that examines the chemical, structural, and physicochemical principles underlying immune recognition and effector function. It bridges biochemistry, structural biology, thermodynamics, and molecular immunology to explain how antibodies, antigens, complement proteins, and immune receptors interact with exquisite specificity and regulated affinity. At its core, immunochemistry addresses a fundamental biological problem: how macromolecules discriminate between self and non-self with high specificity while maintaining sufficient flexibility for adaptive diversity.
This chapter provides a graduate-level treatment of the molecular, thermodynamic, structural, and applied principles that define the field.
