LDH 21 FS (IFCC mod.)

Product No: 1 4251

Description

Lactate dehydrogenase (LDH) is an enzyme, consisting of five different isoenzymes which catalyze the interconversion of L-lactate and pyruvate. LDH is present in the cytoplasm of all human tissues with higher concentrations in liver, heart and skeletal muscle and lower values in erythrocytes, pancreas, kidney and stomach. Increased LDH activities are found in a variety of pathological conditions such as myocardial infarction, cancer, diseases of liver, blood or muscle. However, because of the lack of organ specificity, determination of its isoenzymes or other enzymes such as alkaline phosphatase or ALAT/ASAT is necessary for differential diagnosis. [1,2]

Features

Ready to use reagent.

Proline LDH 21 FS (IFCC mod.) comes in a liquid format which provides convenience for users as no reconstitution is required which helps reduce the risk of misdiagnosis.

Open system reagent, compatible with a wide range of instruments.

Proline LDH 21 FS (IFCC mod.) reagent is suitable for various third party analyzers such as Abbott, Advia, Cobas, Hitachi, Olympus, Response, TokyoBoeki, and Beckman Coulter.
