Immunocytochemistry/ Immunofluorescence: SCP3/SYCP3 Antibody [NB300-231] - Meiotic spreads show deletion of Dicer1 disrupts progression of meiosis I.(A) It was possible to identify the 5 sub-stages of meiosis I by combining the reactivity patterns of two antibodies against synaptonemal complex protein 3 (SYCP3) & gammaH2AX. SYCP3 is a protein essential for synapsis of homologous chromosomes & gammaH2AX localizes to double-strand breaks & XY bodies during meiosis. A total of 200 spreads were counted in testis cell preparations from WT & GCKO mice at P22. (B) Chi square analysis shows GCKO testes contained significantly higher numbers of germ cell spreads at the leptotene & zygotene stages of meiosis I & fewer spreads at pachytene, diplotene & metaphase I stages (P<0.001), suggesting that the loss of Dicer1 lead to disruptions in progression through meiosis I.
