Anti dmc1

The prepared sections were blocked with 3% (w/v) bovine serum albumin (BSA; ZSbio) in PBST (0.1% [v/v] Triton X-100 in PBS) for 1 h at room temperature and then incubated with the following primary antibodies overnight at 4°C: anti-Sycp3 (1:200, Abcam, Cambridge, MA, USA), anti-synaptonemal complex protein 1 (Sycp1; 1:200, Abcam), anti-Vasa (1:500, Abcam), anti-c-kit (1:500, Abcam), anti-Shp2 (1:200, Santa Cruz Biotechnology), anti-Plzf (1:500, Santa Cruz Biotechnology), anti-cleaved caspase 3 (1:200, Cell Signaling Technology, Boston, MA, USA), anti-Dmc1 (1:200, Abcam), anti-Smc3 (1:500, Abcam), and anti-DNA repair recombinase rad51 (Rad51; 1:200, Invitrogen). After being washed three times with PBST, the samples were incubated with the following secondary antibodies at a 1:200 dilution for 1 h at 37°C: Alexa Fluor 594/488-labeled anti-rabbit or anti-mouse IgG (YEASEN, Shanghai, China). The slides were subsequently washed three times in PBST and mounted with Vectashield containing 4’-6-diamidino-2-phenylindole (DAPI; Vector Laboratories, Burlingame, CA, USA).
