Objective

To perform dialysis on the protein extracted from the cells.

Description

  1. Find the sequence of the protein by finding the sequences of the following proteins: MBP, Gyr A, Chitin binding domains.
  2. Use a pI calculator (web address shown below) to determine the pI of the protein. The pI was determined to be 7.327
  3. Use a Misonix Ultrasonic Liquid Processor Sonicator to rip the cells open. The two tubes of cells aquired the previous week were divided into a total of four tubes. Each tube was placed on ice and sonicated 3 times for 30 seconds each, with a 30 second break between each round of sonication.
  4. 4 L of 50 mM Tris with a pH of 9 was prepared. It was divided between 2 large containers
  5. Two pieces of Snakeskin pleated dialysis tubing were cut.
  6. Each of the dialysis tubes were filled with two tubes of the protein extracted from the cells.
  7. Each dialysis tube was placed in its own 2 L container of 50 mM Tris.
  8. The containers were placed in the cold environmental storage room overnight.
  9. 1 L of 50 mM Tris (pH 9) and 1 L of 50 mM Tris and 1 M NaCl (pH 9) were prepared and covered with foil for use the next day.
