FoxP-KO: the homozigous FoxP-KO (with NO Gal4 and NO GFP) had a green signal, it means that the dsRed gives problems. I thus removed it. Also, in really nice dissections, I don´t see the phenotype I was seeing before. The brain looks fairly normal. it could than be that i wasn´t disecting well enough

Hybridoma (Fusion) 1st screen

on Wednesday, October 24th, 2018 5:06

This picture shows all of the positive clones in the ELISA from the 1st screen

While this picture shows just the clones that have a high response for the peptide the mice where injected with, a low response for any other random peptide, and furthermore a low response for BSA

FoxPB adult cell count


I add another animal to the count (so now n=5) and the standard deviation increased. Since I used a very young fly it could be that the cell number is age dependent. But since it can be also individual differences, after San Diego I will make an age related analysis

FoxP-KO or WTB?

on Wednesday, October 17th, 2018 4:04

Here´s  a picture of a WTB fly and a foxP-KO-homozigous. I dissected all together and I did not know which one was which. But I manage to recognize them, which means that they are well recognizable. Just to be sure i will do that another time. (Also in order to have better dissections).

The distance between the two “hemispheres” in the WTB has an average of 5,4 um (n=3)

The distance between the two “hemispheres” in the KO has an average of  32,2 um (n=2)


The length of the protocerebral bridge in the WTB has an average of 95,7 um (n=3)

The the protocerebral bridge in the KO has an average of  140,3 um (n=2)

63x picture of 2 of the FoxPB-Gal4 positive clusters

The dorsal cluster neurons are really evident and with a typical organization

From Hassam et al., 2000

Protocerebral bridge in FoxP-KO flies


The more brains I see, the more I am convinced that the problem is not about my dissection

MB in FoxPB-Gal4 with GFP on the 2nd chromosome (homozigous)


this result is still to be verified by deleting the red fluorescent eyes to the flies

Tries with IMARIS

on Friday, September 21st, 2018 2:07

Me and Anders spent some time at the imaris trying to get confidence with the software. We managed to do volume rendering and we counted the FoxP-isoB positive cells


the count resulted really similar to the one I´ve done by eyes:
