EGFR化合物的靶向筛选已成为肿瘤治疗的医学研究热点之一。将天然表达高水平EGFR的A431与稳定高表达EGFR的细胞系HEK 293进行比较。流式细胞术检测细胞生长情况,Western blot检测EGFR、p-EGFR和p-ERK的表达。细胞膜色谱分析显示A431的峰上色谱更长,峰上面积更大。结果表明,高表达EGFR细胞系A431提高了细胞膜色谱法筛选EGFR靶向药物的灵敏度。
Targeted screening of EGFR compounds has become one of the medical research focuses for tumor therapy. A431, which naturally expresses high levels of EGFR, was compared with the stably high expressing EGFR cell line HEK293. Flow cytometry was used to analyze cell growth and Western blot was used to determine expression of EGFR, p-EGFR and p-ERK. Cellular membrane chromatography analysis revealed longer on-peak chromatographic and greater on-peak area of A431. Results demonstrated that the high-expression EGFR cell line A431 improved sensitivity of cellular membrane chromatography when screening drugs targeted to EGFR.
