Patent CA-2111017-A1 (CA)
Inventor: VANNBY RICKARD
IPC: C01B32/40
Filed: 1993-12-09
Abstract: A process is provided for the preparation of carbon monoxide-rich product gas. The process includes reacting a gas feed of hydrogen and carbon dioxide which has been preheated to a temperature between 400°C and 650°C in a molar H2/CO2 ratio of between 1.5 and 6.5 in the presence of a reforming catalyst at a pressure between 5 and 50 bar to carbon monoxide-rich gas. The process additionally comprises reacting part of the carbon dioxide and hydrogen in the gas feed exothermically to methane simultaneously with the carbon monoxide-producing reaction, and carrying out both reactions under adiabatic conditions. In this way, the exothermic methane-producing reaction provides heat which is necessary for the endothermic carbon monoxide-producing reaction. The outlet temperature of the carbon dioxide-rich product gas is higher than the temperature to which gas feed is preheated.

Title: Decontamination of nucleic acid amplification reactions
Inventor: FRAISER MELINDA S
IPC: C12Q1/6848
Filed: 1994-04-26
Abstract: Methods for inactivating contaminating amplicons in isothermal nucleic acid amplification reactions such as SDA, Q.beta. and 3SR. dU is incorporated into the amplicons produced by amplification in the place of thymine (T). If these amplicons contaminate a subsequent amplification reaction, they may be inactivated as templates (i.e., rendered unamplifiable) by treatment with UDG. As isothermal amplification does not involve elevated temperatures, the UDG may be inactivated during the subsequent amplification of specific target sequences by inclusion of the UDG inhibitor protein Ugi. Incorporation of dU has unexpectedly been found to enhance the amplification power of SDA as compared to conventional SDA  reactions. The methods may also be used to detect UDG activity in reagents or samples.
