We have previously reported that the binding of ethidium bromide to the nucleosome core particle results in a stepwise dissociation of the structure which involves the initial release of one copy each of H2A and H2B (McMurray & van Holde, 1986). In this repor...

RNAase SPL, a ribonuclease isolated earlier from bovine seminal plasma, was shown to possess the ability to produce large acid-insoluble fragments of Mg(2+)-containing RNA in a limit digest. The factor which could be responsible for this apparent specificity ...

We studied the immobilization of a mycelium (Aspergillus niger) using the working hypothesis as follows: (a) when polycation was added to the cell suspension, a few parts of it would bind on the surface of a hypha, allowing to gather the hyphae in part but no...

The properties of the complexes of ferricytochrome c with two different polyanions--poly(vinylsulfate) and poly(4-styrene-sulfonate)--with a comparable charge density but with the different size of the uncharged part of their molecules have been studied by me...

Formation of protein-polyelectrolyte complexes (PPCs) between bovine serum albumin (BSA) and potassium poly (vinyl alcohol) sulfate (KPVS) was studied at pH 3 as a function of ionic strength. Turbidimetric titration was employed by a combination of dynamic li...

The preparation and spectroscopic and microscopic characterization of oriented polyelectrolyte multilayers (PEM) interesting for defined nanostructured functional materials and surfaces are reviewed. Oriented PEM were generated by consecutively adsorbing α-he...

A potentiometric titration method using a cationic surfactant as an indicator cation and a plasticized poly(vinyl chloride) membrane electrode sensitive to the cationic surfactant is proposed for the determination of polyhexamethylene biguanide hydrochloride ...

Polyion complexes of three chitosans with poly(vinyl sulfate) (PVS) and dodecylbenzene sulfonate (DBS) were examined by a potentiometric study that was to separately measure the pH of sample solutions individually prepared. Apparent formation constants (Ki) o...

Interaction of polyanion poly(vinylsulfate) with oxidized cytochrome c (cyt c) significantly affects the protein main characteristics. One of them, pKa value of acidic transition, was shifted from an apparent pKa value 2.5 (typical for cyt c in low ionic stre...

The refolding rate of the Arc repressor dimer can be accelerated 30-fold or more by negatively charged polymers including single-stranded and double-stranded DNA, RNA, and polyvinylsulfate but not by neutral or positively charged polymers. The salt-dependence...
