Product Specification
SENSITIVITY: 0.05μmol/l (expected value: 0.45µmol/l ± 0.19µmol/l)
QUANTITY: 96 wells (~80 tests).
APPLICATION: For the quantitative detection of asymmetrical dimethylarginine (ADMA) in human EDTA-plasma and serum. Does not cross-react with SDMA, NMMA or L-arginine.
SHIPPING: SHIPPED ON BLUE ICE
LONG TERM STORAGE: +4°C
HANDLING: Store standard and controls at -20°C. Store rest of the kit at +4°C.
General Information
Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis. NO is one of the major endothelium-derived vasoactive mediators and is involved in the modulation of blood flow and blood pressure. Even small changes of ADMA concentration alter vascular NO production, vascular tone, and systemic vascular resistence. Elevated ADMA concentrations are found in patients with diabetes mellitus, hypercholeste-rolemia, hypertension, pulmonary hypertension, peripheral arterial disease, chronic renal failure, preeclampsia or erectile dysfunction. ADMA is therefore a novel cardiovascular risk factor.
