该协议可用于更深入地了解哺乳动物颅面发育过程中活性磷酸化蛋白的动力学和作用。该方案克服了从两个生理相关背景(小鼠面部过程和培养的小鼠胚胎腭间充质细胞)分离蛋白质过程中脱磷酸化的常见障碍。必须快速移动,同时将所有试剂和材料保持在冰上,并在所有裂解缓冲液中使用磷酸酶抑制剂,以保持磷酸化蛋白质的完整性。
首先,将小鼠身体放在腹侧朝上,并将小鼠腹部喷洒70%乙醇的解剖板上。然后用直的Semken镊子捏住并抬起阴道口前方的皮肤,以打开腹腔。接下来,用直刀片手术剪刀在两侧以45度角切割抬起

Summary
该协议提出了一种从解剖的小鼠胚胎面部过程或培养的小鼠胚胎腭间充质细胞中分离全细胞蛋白裂解物并随后进行蛋白质免疫印迹以评估磷酸化蛋白水平的方法。
