Immunoelectron microscopy of human retroviruses.
The ultrastructural detection and identification of human retroviruses--HTLV (human T-cell lymphotropic virus) and HIV (human immunodeficiency virus)--have become an everyday task for pathologists and virologists as well as for cell and molecular biologists. The development of better and conventionally available immunocytochemical techniques, such as pre- or postembedding immunocytochemical met...
متن کاملLocalization of calmodulin in rat cerebellum by immunoelectron microscopy
Calmodulin, a multifunctional Ca(++)-binding protein, is present in all eucaryotic cells. We have investigated the distribution of this protein in the rat cerebellum by immunoelectron microscopy using a Fab-peroxidase conjugate technique. In Purkinje and granular cell bodies, calmodulin reaction product was found localized both on free ribosomes and on those attached to rough endoplasmic reticu...
متن کاملLocalization of the low-Mr subunit of cytochrome b558 in human blood phagocytes by immunoelectron microscopy.
Cytochrome b558 is a membrane-bound component of the NADPH-oxidase system in phagocytes and consists of a low-Mr subunit of 22 to 23 Kd and a high-Mr subunit of 75 to 90 Kd. The present study on the subcellular localization of the low Mr subunit of cytochrome b558 (p22-phox) in resting human peripheral blood phagocytes was based on immunogold labeling with monoclonal antibody (MoAb) 449, recent...
متن کاملDetermination of Superficial Clefts on Fragment of Antigen Binding in Human Immunoglobulin G by Computational Immunology
Background: Immunoglobulins (Igs) are protective glycoproteins specifically identify and eradicate microbes. Fragment of antigen binding (Fab) is a portion of antibody which binds to antigen and consists of one variable and one constant domain of one heavy and one light chain. Idiotypes, epitopes situated on Igs variable region, could be exploited to monitor and target malignant B cells and are...
متن کاملCoated vesicles from human placenta carry ferritin, transferrin, and immunoglobulin G.
Coated vesicles prepared by using isotonic gradients retain their contents. Ferritin, transferrin, and immunoglobulin G have been detected in human placental coated vesicles. Triton X-100 extraction of crude coated vesicles removes contaminating uncoated membranes, leaving coated particles and their associated proteins apparently intact; this provides an efficient means of preparing large quant...
