We report the occurrence of cytogamy in Tetrahymena thermophila. By analogy to Paramecium, cytogamy generates exconjugant clones that derive their entire genetic information from a single meiotic product of their cytoplasmic parent. Thus, "instant" whole-genome homozygotes are created. Cytogamy has been induced in every strain of T. thermophila tested, and most of the excytogamous progeny have ...

INTRODUCTION Knowledge of the composition of protein complexes provides key insights into their functions. Immunoaffinity purification provides an effective means for isolating protein complexes and elucidating their composition. Immunoisolation is achieved with antibodies directed either specifically against the proteins of interest or against tags that are coupled to the proteins of interest....

Tetra(4-aminophenyl)ethene shows three paths of ?-conjugation, linear-cis, linear-trans and a cross-conjugation, which only the linear cross configurations are able to show conductance in molecular junctions.
