  • Title: DOT-ELISA for detection of phenolic glycolipid PGL-Tb1 and diacyl-trehalose antigens of Mycobacterium tuberculosis.
    Author: Papa F, Luquin M, David HL.
    Journal: Res Microbiol; 1992; 143(3):327-31. PubMed ID: 1448617.
    Abstract:
    A DOT-ELISA method for detection of 2,3-diacyl-trehalose (DAT, previously referred to as SL-IV antigen) and triglycosyl phenol phthiocerol di-mycocerosate (PGL-Tb1) antigens from Mycobacterium tuberculosis is described. The method enabled the detection of both antigens in 14 clinical isolates of M. tuberculosis from different geographic origins; the presence of the glycolipids was confirmed by chemical analysis. It was therefore concluded that the synthesis of both of these compounds is characteristic of the species.
