WebDNA in mammalian, and most vertebrate sperm, is packaged by protamines into a highly condensed, biochemically inert form of chromatin. A model is proposed for the structure of this DNA-protamine complex which describes the site and mode of protamine binding to DNA and postulates, for the first time, specific inter- and intraprotamine interactions … WebMar 17, 2024 · They are biochemically inert do not ferment carbohydrates.

WebJul 3, 2024 · These results open an avenue to fabricating biochemically inert supercapacitor devices. Abstract. Supercapacitors store charge by ion adsorption or fast redox reactions on the surface of porous materials. One of the bottlenecks in this field is the development of biocompatible and high-rate supercapacitor devices by scalable … WebMost peptide-tags are biochemically inert: they generally don’t affect protein folding and solubility and don’t interfere with protein function. In contrast, protein tags such as Maltose Binding Protein (MBP) and Glutathione-S-Transferase (GST) can increase the solubility of a protein and facilitate correct folding.
