    Gp340 is a member of the scavenger receptor cysteine-rich family of innate immune molecules and also functions as a tumor suppressor. This study describes a picogram-level assay using electrochemiluminescence technology on the MesoScale Discovery platform. Antibodies were evaluated and the best pair was used to assay whole-mouth stimulated saliva and cervical/vaginal lavage. The assay was tested using specimens obtained from healthy volunteers to determine if gp340 concentration in saliva correlates with levels in vaginal lavage fluid. Interestingly, no correlation was determined between gp340 content in these two fluids.
