Note: Constantly use appropriately titrated antibodies and tetramers, which is commonly not the concentration advised by the supplier. The ins and outs of titrating antibodies can be discovered while in the publication of Lamoreaux et al. 421.Writer Manuscript Writer Manuscript4 Intracellular stainings of transcription factors and cytolytic molecules 4.one Following surface staining include 200 L Fixation/Permeabilization buffer. 4.two Gently resuspend the cells by pipetting up and down 3 times. 4.3 Incubate for twenty min at four , shaking, protected from light. four.four Centrifuge for five min at 700 g at four . 4.five Aspirate supernatant and resuspend cells in 200 L flow cytometry buffer and centrifuge for five min at 700 g at 4 . four.six Aspirate supernatant and resuspend cells by pipetting up and down three occasions in 50 L of the intracellular staining combine prepared in Permeabilization Buffer. four.seven Incubate thirty min at 4 , shaking, protected from light. four.eight Include 150 L Permeabilization Buffer to each very well and centrifuge for five min at 700 g at four . 4.9 Aspirate supernatant and resuspend cells in 200 L Permeabilization Buffer and centrifuge for five min at 700 g at 4 . 4.ten Aspirate supernatant and resuspend cells in one hundred L movement cytometry buffer and analyze by flow cytometry cell sorting while in the desired format.Writer Manuscript Writer Manuscript5 Cytokine staining five.1 Transfer PBMC into suspension culture flasks (690 190, Greiner) at one 106 cells/mL in culture. medium (flask standing upright, or 45Eur J Immunol.
