WebPulse chase experiments can be divided into three stages: 1) the actual pulse chase, 2) immunoprecipitation of the protein of interest, and 3) sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis . At the end of each stage, samples in principle can be snap-frozen in liquid nitrogen and stored at −80°C. WebThe DNA of the virus was tagged with radioactive phosphorus in one experiment, and this ended up in the pellet. The protein shell of the virus was tagged with radioactive sulphur, and this ended up in the supernatant.
