PULSE-CHASE PRIMER: THE MESELSON-STAHL EXPERIMENT INTRODUCTION In the 1950s, James Watson and Francis Crick suggested a mechanism for the replication of DNA, which they called the “Semiconservative Model of Replication ” During replication, each of the two strands of DNA would act as a template for the synthesis of a new strand
May 11, 2014 · 1 Each pulse-chase will require a 20 ml culture of yeast at an OD 600 of between 0 4 and 0 6 To do this, I usually set up a number of 20 ml cultures the evening before, innoculated at different densities, so that first thing next morning at least one of the cultures will be at an OD 600 of ~0 5 B PULSE-LABELING
- Pulse: Add 0 35 ml of [35S]-Meth working solution Incubate 30 min at 37°C - Chase: Add 0 75 ml of chase medium to the [35S]-Meth solution and remove - Wash once with 1 ml of pre-warmed chase medium - Add complete medium (DMEM + 10 FBS) Treatments, such as Wnt3a or Lactacystin, can also be added at this point

What is the pulse-chase technique?
Pulse-chase technique is a method that involves culturing cells in a medium containing labeled amino acids for a short period of time known as 'pulse'. This results in the generation of newly-synthesized polypeptides incorporating labeled amino acids.What is Pulse vs Chase?
During the pulse phase of the experiment, cells are exposed to a labeled compound. The labeled compound is incorporated into the molecule or pathway being studied. In the chase phase, an unlabeled form replaces the labeled compound.- Pulse-chase experiments are often used to study the degradation of macromolecules such as proteins or mRNA.
