Indicator, Substrate

EXTRA NOTES

Colorless to yellow dye that is reducible to blue or black formazan crystals by certain cells; formerly used to distinguish between nonbacterial and bacterial diseases, the latter causing neutrophils to reduce the dye; used to confirm diagnosis of chronic granulomatous disease.[MeSH]
Substrate for dehydrogenases and other oxidases
