WebScrew the cap on the reaction vessel and cool in a dry ice methanol bath for at least 5 min before proceeding with the cleavage. Distil 10 mL of HF into the flask following the manufacturer’s instruction (maintaining the temperature between -5 °C and 0 °C). For peptides containing Arg(Tos) the reaction will require up to 2 h. WebTo the clarified homogenate, add 1 ml of 10% (w/v) N -laurylsarcosyl and heat the sample for 2 min at 65 °C in a water bath. Add cesium chloride (0.6 g solid CsCI) to give a final concentration of 1.2 M, and then layer the homogenate onto 5 ml of a 5.7 M cesium chloride solution containing 0.1 m M EDTA, pH 7.0, in a siliconized polyallomer tube. the screen rant
