phospho-Smad2 (Ser250) Polyclonal Antibody

Hela cells were\u00a0fixed with 4% PFA for 10min at room temperature,permeabilized with\u00a090% ice-cold methanol for 20 min at -20\u2103,\u00a0and incubated in 5% BSA blocking buffer\u00a0for 30 min at room temperature. Cells were then stained with phospho-Smad2 (Ser250) Polyclonal Antibody(bs-20314R)at 1:100 dilution\u00a0in blocking buffer and\u00a0incubated for 30 min at\u00a0room temperature,\u00a0washed twice with 2%BSA in PBS,\u00a0followed by\u00a0secondary antibody incubation\u00a0for 40 min\u00a0at\u00a0room temperature. Acquisitions of 20,000 events were performed.\u00a0Cells stained with primary antibody\u00a0(green), and isotype control (orange).
