Fig. 2From: Low oxygen tension increases mitochondrial membrane potential and enhances expression of antioxidant genes and implantation protein of mouse blastocyst cultured in vitroImmunofluorescence staining images showed that a HIF-2α, b MnSOD and c LIFR protein expression levels were all higher in embryos cultured in 3% O2 than in those cultured in 20% O2. Secondary antibody conjugated with Alexa flour 568-labeled HIF-2α (b, e), LIFR (n, q), and Alexa 488-labeled flour MnSOD (h, k) proteins with DAPI staining of nuclei (a, d, g, j, m, p) and merged images (c, f, i, l, o, r).
