Performance of the ASTRA enzyme systems evaluated.
We evaluated the ASTRA enzyme systems for the kinetic measurement of some commonly measured enzymes. The comparison studies with the SMAC and the LKB 8600 show that results by the ASTRA enzyme systems correlate well with those by our routine methods. Studies with several control sera yielded excellent results for both within-run and between-day variation. The response of the photometer is linear up to 3.0 A. For three enzymes the range of linearity exceeded the limits proposed by the supplier, but for lactate dehydrogenase it did not extend as far as proposed. Reagents are stable for at least one week at 16-24 degrees C.
