An International Review Series Devoted to Proteins and Related Studies, Volume 32: Protides of the Biological Fluids documents the proceedings of the 32nd Colloquium held in 1984. This compilation is organized into three parts. Part I begins with an introduction to the defense mechanism of immunoglobulins, followed by a description of enzymes and proteins, such as lactoperoxidase and lactoferrin. The secretions that include CSF, colostrum, milk, female and male genital secretions, saliva, gastrointestinal juice, nasal and bronchoalveolar secretions, tears and synovial fluid are also elaborated. The tumor markers, which include ferritin, CEA, and TPA are dealt with in Part II. The immunotoxins, tumor imaging, and lymphoid malignancies are also covered. Part III is devoted to the advances in the separation of protides, including the staining procedure for protein detection, two-dimensional electrophoresis, and HPLC and affinity chromatography. This book is valuable to biology students and clinicians of disciplines related to advances in the protein field.
