Figure 2From: Peroxiredoxins: hidden players in the antioxidant defence of human spermatozoaDifferential immunolocalization of PRDXs in human spermatozoa. Spermatozoa were permeabilized or not with methanol and incubated overnight with the specific antibody against each PRDX and then with the corresponding biotin-labelled anti-mouse or anti-rabbit antibody followed by streptavidin conjugated to Alexa Fluor 555 [42]. The fluorescence obtained with the second antibodies and the Alexa Fluor 555-conjugated streptavidin alone was low and only at the level of the sperm head and equatorial segment (data not shown).Back to article page
