New version of FkTRXR-03-STAR

FkTRXR-03-STAR has a new upgraded content. Standard rat rTrxR ( 40µl of 14 Units/ml in 50 percent glycerol) is added in the kit. From this dilutions to 10 mUnits/ml is made to ensure fully active enzyme at the time of assay generating a standard curve

This assay is extremely sensitive and is based on Trx-dependent disulfide reduction of a fluorescent substrate.

New kit for high sensitivity GSH measurements

Measuring GSH in plasma and serum requires high sensitivity and is complicated by oxidation in samples upon storage. IMCO has developed a new kit for high sensitivity fluorescent determinations of GSH, GSSG and glutathionylated products.


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.
