EmbryoLysates&Immunoprecipitation
Embryo lysatesTake 25 embryos and place into 1.7ml centrifuge tube.Rinse once in lysis buffer (add ~ 1ml) and remove by aspirationAdd 500 µL lysis buffer per embryo and homogenize with either P1000 tip.Add 1000 µL freon -- vortexspin in cold room, top speed - 10-15 minutestake the supernatant - either freeze at -80°C or use immediately for blot, immunoprecipitation, DNA-fishing or whatever else suits your fancy.For b......阅读全文
