Gamma-glutamyl transferase (GGT)
| Engelsk navn: | Gamma-glutamyl transferase | |
| Analyseinstrument: | Advia®1800 | |
| Reagensprodusent: | Siemens Medical Solutions Diagnostics | |
| Analyseprinsipp: | Modified IFCC In the reaction with synthetic substrate (L-γ-glutamyl-3-carboxy-4-nitroanilide), glycylglycine acts as an acceptor for the gamma-glutamyl residue and 5-amino-2-nitro-benzoate (ANB) is liberated. The liberated product has an absorption maximum near 400 nm; the rate of formation is measured photometrically at 410 nm as a zero-order kinetic assay.(Metoden tatt i bruk: 1/7-01) | |
