NADPH in kits
2017.03.02

NADPH is used in the fluorescence kits from IMCO for assay of Trx, Grx or TrxR. Solutions of NADPH are only stable for about 10 days even if stored frozen.

You can make a fresh solution by dissolving 2 mg of NADPH in 0.5 ml of buffer. A solution of NADPH which is turning yellow should be discarded. By making fresh NADPH your assay will work for a long time. Other components of the kits are stable if stored frozen or according to the kit instructions.

Mammalian thioredoxin reductases: TR-03 and TR-03B

Mammalian thioredoxin reductase 1 (TrxR) contain an essential seleocycteine residue encoded by the stop codon UGA. This makes recombinant expression in E.coli a challenge. IMCO now has preparations of rat TrxR with unsurpassed specific activity.
