Abstract

A long-shelf life activated carbon includes activated carbon impregnated with salts of copper, zinc, and molybdenum, and TEDA, wherein the activated carbon is also impregnated with phosphate. The phosphate may be supplied from any source, and in particular from sodium or potassium phosphates. The phosphate may be impregnated before or after the aforementioned salts. The phosphate prevents aging of the activated carbon against gases such as cyanogen chloride, as demonstrated with experiments conducted under conditions of both open accelerated aging and closed accelerated aging. The long-shelf life activated carbon may be included in an air filter.

Abstract

An organophosphate scavenger is provided, with extended residence time in the mammalian circulation, which can be used in preventive and therapeutic treatment of organophosphate poisoning. The scavenger is a uniformly pegylated serine hydrolase, in which a part of lysine residues were replaced with other residues by site-directed mutagenesis. One part of lysine residues in the hydrolase amino acid sequence is selected for the PEG-coupling, and the other part for the replacement, wherein the selection should ensure that the hydrolase surface shows at least one free amino acid for PEG coupling for all possible views obtained by rotating a 3-D model generated for the hydrolase.
