摘　　要：目的比较市售单组分TMB显色液的质量。方法选购4种国内外代表性产品,从外观、灵敏度、稳定性等几个方面进行对比。结果两种进口试剂的灵敏度高于两种国产试剂,但本底高于国产试剂。37℃5d加速稳定试验发现,进口试剂和国产试剂均保持稳定,但进口试剂本底显著升高。结论市售单组分TMB显色液质量参差不齐,价格相差甚远。Objective To compare the quality of commercially available 3,3＇,5,5＇--tetramethylbenzidine liq- uid substrate. Methods The appearance,sensitivity and stability of four representative products made in China and other counties were compared. Results The sensitivity of two kinds of domestic reagent were higher than that of for- eign reagents, but the background was also higher than the domestic reagents. All the reagents were stable after ac- celerated stability test at 37 ℃ for 5 days, but the background of the foreign reagents increased significantly compared to that of the domestic reagents. Conclusion The quality of the commercially available 3,3＇, 5,5＇ -- tetramethylbenzidine liquid substrate is far different,and the price is very different.
