We investigated the interaction of large DNA with protamine, a small basic protein, using fluorescence microscopy and electron microscopy. In most vertebrate sperm cells, a large DNA is packaged by protamine into a highly compact, biologically inactive form of chromatin. The manner of packaging plays a key role in spermatogenesis. We found that, with increase of protamine concentration, DNA molecules...
Quantum-dots-tagged poly(styrene-acrylamide-acrylic acid) microspheres (QDsAAMs) were synthesized and modified with hydrazine hydrate through hydrazinolysis. Azidocarbonyl groups, which can be rapidly coupled with proteins under mild conditions, were introduced onto the surface of QDsAAM using azido reaction. Bovine serum albumin (BSA) was selected as model protein to be covalently immobilized on...
In cell biology, modern imaging techniques using fluorescence microscopy allow to visualize specific nuclear structures in situ in the same cell nucleus. Hence, distances between these structures can be evaluated, in particular co-localization can be investigated. When the nucleus alters its global shape, especially if the structures are imaged sequentially, the distances are changing as well and...
