Abstract
Staining of transcription factors (TFs) together with retention of fluorescent reporter proteins is hindered by loss of fluorescence using current available methods. In this study, it is shown that current TF staining protocols do not destroy fluorescent proteins (FPs) but rather that fixation is not sufficient to retain FPs in the cytosol of the permeabilized cells. In this article, a simple and reliable protocol is elaborated, which allows efficient TF and cytokine staining while retaining FPs inside fixed cells.Keywords: EGFP; EYFP; FoxP3; RFP; RORγt; T-bet; fate mapping; fixation; flow cytometry; formaldehyde; mouse T cells
