Figure 2From: Method to isolate polyribosomal mRNA from scarce samples such as mammalian oocytes and early embryosNeutralization of formaldehyde in Drosophila SL2 cell extract. Total RNA recovered from cell extracts (the clarified supernatant) treated with 3.37% formaldehyde, quenching the reaction using A) Glycine at pH 8.7; B) Tris at different concentrations and pH; C) Tris at a broad range of concentrations at pH 8.7Back to article page
