Flow cytometry of pancreatic islet cells was performed as previously
described
60 (link). Islet
cells were fixed and permeabilized with the
Foxp3 staining kit (eBioscience) and
then stained with APC-conjugated antibody to insulin (clone 182410, R&D
Systems), Alexa Fluor 488–conjugated antibody to GFP (Invitrogen) and
antibody to glucagon (clone 199017, R&D Systems; PerCP-Cy5.5 labeled
using the
Lightning-Link labeling kit from Innova Biosciences).
