In a recent post, I was musing about why the SmartFlares weren’t in the swollen chloroquine-induced vacuoles. Out of interest more than anything, I did a quick experiment to see what would happen if I pre-labelled the endocytic pathway with one coloured dextran, then added in a second with the chloroquine.
I recently discussed the SmartFlare project at a joint Sée and Lévy Group Meeting, partially extolling the virtues of Open Science but mostly focussing on the data acquired so far and some of the proposed experiments.
Regarding the SmartFlare project, the three big questions that formed the basis of the talk were:
- Why do only some cells take up SmartFlares?
- Where are the SmartFlares?
- Why are the VEGF and Scrambled SmartFlares fluorescent in puncta?
Below are some of the interesting points that were made during the meeting. Replies at the time (as best as I can remember them) in green:
As discussed in a previous post, the punctate distribution of all of the SmartFlares (SFs) is both unexpected and curious. In order to better understand where the SFs are localised in the cell, we would like to do a fairly routine co-staining experiment.
