cell stimulation
Culture CD4 T cells in 96-well flat bottom plate, 0.4 M cell per well, stimulate cells with 50 ng/ml PMA, 1 ug/ml Ion and Golgiplug for 5 hrs, then FACS staining.
加入抗CD3 mAb ,抗 CD28 mAb就是刺激的其中一种方法,CD3和Anti-CD3结合,anti-CD28相当与CD80、CD86的作用,印象中好像叫是共刺激分子。注意加进去的抗CD3 mAb ,抗 CD28 mAb这两个抗体是没标记的,作用就是为了刺激,而CD4是FITC标记的,是用于检测。
