We are interested in studying the mechanisms responsible for ensuring T cell self tolerance that rely on thyme and extra-thymic Aire expressing cells.

Experimental Design and Results Summary

Applications

Flow Cytometry

Sample

Mouse thymus

Primary Incubation

Live dead: Zombie NIR LD 1:4000 in 100ul FACS for 20 min at RT

Blocking Agent

2.4G2

Secondary Incubation

Surface stain: Cd104 1:400 in 100uL FACS for 30 min at 4C

Tertiary Incubation

PFA (15 min RT) + FoxP3 Fix/Perm kit (30 min 4C), then intracellular stain in 100uL perm buffer for 1hr at RT

Detection

Cytek Aurora spectral flow cytometry

Results Summary

This antibody stains thymic mTECs extremely brightly by spectral flow cytometry, making it difficult to separate true positive and negative populations. Titrating to get optimal staining took several experiments to dial in use, with significant variation from machine to machine.

Summary

The Good

Very bright staining.

The Bad
