Fig. 3From: Anti-oxidant mediated normalisation of raised intracellular cytokines in patients with reproductive failureGating strategy based on pan lymphocyte marker CD45+, with positive staining for markers CD3 and CD8 and negative gating to acquire the CD4+ T-lymphocytes. Intracellular cytokine expression is then measured in the CD4+ cells. This strategy is required as CD4+ surface marker expression is suppressed by the stimulatory processBack to article page
