I n studying the molecular structure of the 3'-globulins, one is confronted at the outset with the problem of whether these proteins consist of one or of several polypeptide chains. The solution of this problem has significance in determining the chemical basis of antibody specificity, and in formulating a detailed theory of antibody production. In(More)
The alloantigen Qa-2, whose gene is located on the 17th chromosome between H-2D and Tla, is identified as a molecule of 43,000 daltons which is associated with beta 2-microglobulin. Qa-2 comprises approximately 0.15% of the iodinateable cell surface protein of lymph node cells. Sequential precipitations demonstrated that Qa-2 is distinct from H-2D and H-2K(More)
Serum beta2-microglobulin levels were measured, by radioimmunoassay, in patients suffering from a variety of benign and malignant clinical disorders. Elevated beta 2-microglobulin values were found in neoplastic and non-neoplastic disorders affecting a variety of organs. The most striking increases in beta 2-microglobulin are found in the plasma cell(More)
ItL-A antigens prepared from human lymphoid cells by treatment of either intact cells or membranes with papain or nonionic detergents have been shown to contain two polypeptide chains. The antigen prepared by treatment of cells or cell membranes with papain contains polypeptide chains with a mol wt of about 34,000 and 11,000 (1), whereas the(More)
Part I highlights the mechanisms of glomerular filtration and tubular reabsorption of plasma proteins, selected characteristics of urinary proteins based upon electrophoretic properties and recent advances in clinical laboratory analysis of proteinuria. Both structural characteristic of the glomerular capillary wall and molecular properties of plasma(More)
