ABSTRACT:
A dry chemistry dye indicator composition provides improved shelf life, stable color indication end point and capability for a system at near normal pH. The novel dry chemistry dye indication system comprises 3-Methyl-6-(sodium sulfonate)-benzothiazolinone-(2)-hydrazone (MBTH-S). A preferred dye systems are based on the dye couple (MBTH-S) and 8-anilino-1-naphthalenesulfonate (ANS), and the dye couple MBTH-S and N-(3-sulfopropyl)analine. These dye indicator systems are used in conventional blood chemistry test strips and are particularly preferred for indication of glucose in blood.
