Studies on the antigen antibody reactions

Immunohistologic Studies on Antigen-antibody Reactions in the Avascular Cornea

The injection of antigen into the center of the avascular cornea of homologously sensitized animals induced a ring of opacification between the center of the cornea and the limbus. This ring of opacification was composed of a line of deeply eosinophilic amorphous material in a matrix of swollen collagen fibers, palisaded by polymorphonuclear leucocytes. By use of fluor-tagged antigen, it was sh...

Studies on Antigen-antibody Complexes

Solid phase immunoadsorbents were prepared by coupling antigens to agarose. With this technique specific antibodies were easily isolated in large amounts. The gammaG-globulin class of antibodies isolated in this manner were not denatured as judged by their normal biological half-life in rabbits. Soluble immune complexes at fivefold antigen excess were prepared from isolated specific antibodies ...

Antigen-antibody Reactions in Allergic Human Tissues

Skin sensitizing human antibodies were conjugated with various fluorescent dyes without significant loss in their ability to combine with specific antigen in vitro. A biopsy of the skin site challenged with egg albumin in a patient sensitive to this antigen could be stained specifically by the fluorescent reagins. The epithelial cells of the epidermis, sweat glands, hair follicles, and sebaceou...
