Beyond the Gender within the Gender—Similarities between Christine de Pican and Qingzhao Li

Christine de Pican and Qingzhao Li were both highly valued due to their unique visions, more importantly, beyond their gender visions in the context of humanity. Both of them shared some similar family background, similar stimulus to write challenging and wonderful articles, similar theme in their later writings.

pICln蛋白单克隆抗体的制备及初步鉴定

目的:制备特异性的抗pICln蛋白的单克隆抗体(McAb),为pICln的纯化及检测等提供必要的工具。方法:以pICln的合成肽为免疫原,对BALB/c小鼠注射免疫,将免疫鼠脾细胞和小鼠骨髓瘤细胞NS-1进行细胞融合,用显微镜下挑选单个克隆的克隆化方法克隆化,用间接ELISA检测法进行筛选。单抗的效价、亚型及特异性用ELISA、免疫双向扩散实验和Western blot等检测。结果:获得了稳定的分泌型杂交瘤细胞株大2B7和4A3,2B7培养上清液单抗效价为1∶64,属IgG1亚型,其腹水抗体效价及纯化抗体的效价分别为1∶1.28×104、1∶6.4×103,Western blot及免疫耗竭实验呈现一条约40kD的特异性带,免疫组织化学染色显示在细胞核和细胞质中呈现阳性反应。结论:本次制备的单抗具有特异性、高效价,可应用于pICln蛋白的纯化及检测等研究。
