- Made TB buffer (DH5-alpha competent cell buffer). 5mLs of 1M HEPES buffer (final concentration 10mM), 75mL of 0.1M CaCL2*2H2O (final concentration 15mM), 9.32g KCl (final concentration 250mM) was added to a beaker. Volume was brought to 300mL. pH was brought to 6.7 with 6.25M KOH. 5.44g of MnCL2*4H2O (final concentration 55mM) was added, and the volume was brought to 500mL. The contents of the beaker were sterile filtered into a sterile bottle purchased from the basement store.

Notebook: Week 2

Monday

- Meeting scheduled in the Med School TAC building with Martin and Girish tomorrow at 2:30pm about using their plasmids with the anti-freeze glycoprotein that they isolated. - Meeting scheduled for Friday with Farren at 2:30pm in West Campus, building B-31, Room 209.

- Made TB buffer (DH5-alpha competent cell buffer). 5mLs of 1M HEPES buffer (final concentration 10mM), 75mL of 0.1M CaCL2*2H2O (final concentration 15mM), 9.32g KCl (final concentration 250mM) was added to a beaker.

The contents of the beaker were sterile filtered into a sterile bottle purchased from the basement store.
