We took out one 2 microliter aliquot of FITC tubulin from last week. Polymerized MTs for 20 minutes using the thermal cycler at 37C with hotlid. Stabilized by adding 198 ul of room temperature BRB80-T

Antifade cocktail

Steve Koch 18:32, 26 May 2009 (EDT): For this, we used some old frozen components:

  • 10 microliters of Glucose oxidase (GOD) from last summer
  • 10 microliters of Catalase (CAT) from last summer
  • 5 microliters of an aliquot of beta-mercaptoethanol (BME) frozen at -20C from last summer.

Brigette mixed up this for a total of 25 ul of antifade cocktail.

Microtubules in antifade viewing solution

  • 85 microliters of BRB80T
  • 10 microliters of polymerized MTs
  • 2.5 microliters of AF cocktail
  • 2 microliters of "1.6 M Dextrose"
    • We made the dextrose in a very rough manner, just weighing out some powder and then adding in a volume based on the printed lines on the 50 mL centrifuge tube.


Steve Koch 18:41, 26 May 2009 (EDT): To visualize, we just put a 5 microliter drop onto a coverglass and then put the coverglass on a slide. We marked the coverglass with a sharpie to make it easy to find the sample plane.
