Mapping of histone H5 sites on nucleosomes using immunoelectron microscopy.
The location of histone H5 on nucleosomes has been determined by binding anti-H5 antibodies to dinucleosomes, and recording the position of the bound IgG molecules using electron microscopy. Two types of antibody were employed, a total IgG fraction prepared from rabbits immunized with H5/RNA, which reacted to all three domains (NH2-terminal, central globular, and COOH-terminal) of H5, and an im...
متن کاملImmunoelectron 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 کاملImmunoelectron microscopy of aldehyde-fixed yeast cells.
Immunolocalization of antigens in cells requires simultaneous preservation of structure and antigenicity. The difficulties of immunolocalization methods are centered around the methods used to preserve structure, which as a rule tend to degrade the ability of antigens (usually proteins) to be recognized by their cognate antibodies. The value of immunolocalization for cell biology was early reco...

15 صفحه اولStabilization of Nucleosomes by Histone Tails and by FACT Revealed by spFRET Microscopy
A correct chromatin structure is important for cell viability and is tightly regulated by numerous factors. Human protein complex FACT (facilitates chromatin transcription) is an essential factor involved in chromatin transcription and cancer development. Here FACT-dependent changes in the structure of single nucleosomes were studied with single-particle Förster resonance energy transfer (spFRE...
