Interaction of Poly-l-lysine with Chromatin
The priming capacity of chromatin of fixed nuclei and chromosomes for exogenous DNA polymerase can be evaluated radioautographically by the incorporation of labeled nucleotides. It had previously been reported that acid fixation or acid treatment of alcohol-fixed tissues led to increased priming when calf thymus DNA polymerases, specific for single-stranded DNA, were used. We employed Escherich...
متن کاملSynthesis and Phase Behavior of Poly(N-isopropylacrylamide)-b-Poly(L-Lysine Hydrochloride) and Poly(N-Isopropylacrylamide-co-Acrylamide)-b-Poly(L-Lysine Hydrochloride)
The synthesis of poly(N-isopropylacrylamide)-b-poly(L-lysine) and poly(N- isopropylacrylamide-co-acrylamide)-b-poly(L-lysine) copolymers was accomplished by combining atom transfer radical polymerization (ATRP) and ring opening polymerization (ROP). For this purpose, a di-functional initiator with protected amino group was successfully synthetized. The ATRP of N-isopropylacrylamide yielded narr...
متن کاملEnhancement by poly-D-lysine of poly I: C-induced interferon production in mice.
Poly-d-lysine of high molecular weight enhances interferon induction in mice by the double-stranded complex of polyinosinic and polycytidylic acids and is superior to diethylaminoethyl-dextran in this respect.
متن کاملPoly-L-lysine amplification of protamine immobilization and heparin adsorption.
We previously reported the development of a cellulose fiber based blood filter device containing immobilized protamine (termed protamine filter) that could be used to control both heparin- and protamine-induced complications during extracorporeal therapy. To achieve enhanced heparin adsorption on the fibers, we examined the possibility of utilizing the poly-L-lysine based amplification method t...
متن کاملThe synthesis and enzymatic hydrolysis of poly-D-lysine.
In studies of the inhibition in viva of animal viruses by poly-n-lysine, Rubini et al. (1) and Green et al. (2-4) obtained data which suggested that poly-L-lysine is hydrolyzed by the proteolytic enzymes of the allantoic fluid, and that this enzymatic hydrolysis may limit its biological activity. The enzymatic hydrolysis of poly-n-lysine was reported by Katchalski (5) and by Waley and Watson (6...
