Abstract:
A biosensor was used for the analysis of catecholamines in media and lysates of cultured bovine adrenal chromaffin cells. The sensor is composed of coimmobilised laccase and glucose dehydrogenase coupled with an oxygen electrode, using the catalytic effect of cate cholamines for glucose oxidation in this system. The analysis time is almost 5 min. The correlation between the biosensor and HPLC determination is 0.99.
