説明
BD Phosflow™ Perm Buffer III is intended to be used for the permeabilization of fixed PBMCs or lysed whole blood. PBMCs, for example, can be stimulated with kinase activators, such as phorbol esters, and can be fixed with BD Phosflow™ Fix Buffer I (Cat. No. 557870) followed by permeabilization of the cells with BD Phosflow™ Perm Buffer III to allow for an effective intracellular staining of kinases. Designed for optimal fluorescent staining in flow cytometry, BD Phosflow™ Perm Buffer III can be used with antibodies for phospho-protein analysis (i.e the staining of intracellular proteins involved in cell signalling pathways, such as phosphorylated proteins and assorted kinases). In many cases, these phospho-specific antibodies may be used simultaneously with the staining of cell surface markers (e.g CD markers). Not all cell surface markers, however, are compatible with BD Phosflow™ Perm Buffer III. For a current listing of compatible cell surface markers for use with BD Phosflow™ Perm Buffer III, investigators are encouraged to visit the following website: http://www.bdbiosciences.com/documents/antibodies_human_cellsurface_marker.pdf.

推奨アッセイ手順
Flow cytometry:
1. Warm BD Phosflow™ Fix Buffer I (Cat. No. 557870) to 37 °C prior to use.
2. Chill BD Phosflow™ Perm Buffer III to -20 °C prior to use.
3. Collect PBMCs after Ficoll-Paque separation and treat with any appropriate cell activators as applicable.
4. At the end of the treatment, immediately mix one volume of the warmed BD Phosflow™ Fix Buffer I with one volume of the PBMC suspension. Mix well and incubate the tubes in a 37 °C water bath for 10 min. Spin down the cells at 250 x g for 10 min in a table-top centrifuge and then aspirate the supernatant.
5. Wash the cells once with BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656). Alternatively, 1X Washing/Staining Solution (1 x PBS, 1% FCS, and 0.09% sodium azide) may be used. Centrifuge to pellet the cells and remove the supernatant.
6. Vortex to loosen the cells. Permeabilize the cells by slowly adding cold BD Phosflow™ Perm Buffer III while vortexing. Incubate on ice for 30 min and then spin down the cells.
7. Wash the cells twice with 5-10 mL of BD Pharmingen™ Stain Buffer (FBS). Centrifuge at 250 x g for 10 minutes and remove the supernatant by aspiration.
8. Resuspend cells in BD Pharmingen™ Stain Buffer (FBS) at 1x 10^7/ml and aliquot 100 µl to each flow tube to continue with antibody staining and flow cytometric analysis.
Danger: BD Phosflow™ Perm Buffer III contains 87.68% methanol (w/w).
