CAT (AD/NAD/DA) - ELISA
EA603/288
Enzyme Immuno Assay
for the quantitative determination of
Adrenaline / Noradrenaline / Dopamine in Plasma and Urine
3x96 Determinations
The assay kit provides materials for the quantitative measurement of adrenaline, noradrenaline and dopamine in plasma and urine; 3 x 96 determinations.
Noradrenaline, adrenaline and dopamine are extracted using a cis-diol-specific affinity gel and acylated to N-acylnoradrenaline, N-acyladrenaline and N-acyl-dopamine and then converted enzymatically into N-acylnormeta¬nephrine, N-acylmetanephrine and N-acyl-3-methoxytyramine.
The competitive CAT ELISA kit uses the microtitre plate format. Adrenaline, noradrenaline and dopamine, respectively, are bound to the solid phase of the microtiter plate. Acylated catecholamine from the sample and solid phase bound catecholamine compete for a fixed number of antiserum binding sites.

The lower limit of detection was determined by taking the 2fold standard deviation of the absorbance of the Zero Reference and reading the corresponding value from the standard curve.
Adrenaline Noradenaline Dopamine
Sensitivity (Urine): 0.08 ng/ml 0.24 ng/ml 0.44 ng/ml
