#Second try: In the second trial, I got some microtubules, but really big fluorescent clusters. This might have been due to the fact that I used old aliquots of the 29% Rhodamine-labeled tubulin suspension. | #Second try: In the second trial, I got some microtubules, but really big fluorescent clusters.

#On my third trial, I got a lot of microtubules. The sample was way more populated than expected.

I really don’t know why this is, I have the suspicion that it has to do with where on the tube I collected the volume of tubulin with Taxol in PEM. Discussing this with Andy, he said that it shouldn’t really matter. Furthermore, the image didn’t have a lot of contrast between the microtubules and the background. This might have to do with the way I focused the sample or maybe just with the fact that my sample was really overpopulated. | ||
