Methylation of the +99/+229 <i>NFKB1</i> promoter region of different cell lines of human lymphocyte cells.

The cells were stimulated with LPS (1 μg/ml), 10 μg/ml LTA or left unstimulated, and DNA was extracted for methylation analysis (n = 2).将细胞以1 μg/ml脂多糖（Lipopolysaccharide，LPS）、10 μg/ml脂磷壁酸（Lipoteichoic acid，LTA）进行刺激，或不给予刺激作为对照，随后提取DNA用于甲基化分析，实验样本量n=2。
