[Immobilization of EcoR1, Pae1 and Lpl1 restriction enzymes].

In search for sorbents (silica gels, styrene-divinylbenzene copolymers), for immobilization of some restriction endonucleases, derivatives of trityl-containing silochroms are shown to bind EcoRI, PaeI and LplI endonucleases with the retention of 10-20, 60-70 and 40-60% activity, respectively. The immobilized restriction endonucleases have the unchanged substrate specificity, can be used several times and are stable at storage. Tritylaminopropylsilochrom is suggested to be the sorbent of choice.

[Ion-exchange hemosorption in the intensive therapy of liver insufficiency in patients with obstructive jaundice].

Hemosorption on thromboresistant ion-exchange resins synthetized at D. I. Mendeleev Moscow Chemical Technological Institute (MCTI) was used in combined therapy of hepatic failure.
