Enhancement of nitroblue tetrazolium dye reduction by leucocytes exposed to a factor released from sensitised
The Australian Journal of Experimental Biology and Medical Science
|February 1, 1979
Abstract:
Leucocytes from purified protein derivative (PPD) skin test positive individuals, after exposure to PPD in vitro, show a significant increase in nitroblue tetrazolium (NBT) dye reduction when compared to leucocytes from PPD negative donors. The active principle was shown to be soluble, and was released from lymphocytes after a rapid, immunologically specific interaction with the sensitising antigen.
