背景介绍
CHEK1(Checkpoint kinase-1) is also named as CHK1 and belongs to the protein kinase superfamily. It is implicated in a circuit in which it activates checkpoints, DNA repair and proliferating cell nuclear antigen and FANCD2 monoubiquitinylation(PMID:21389083). CHEK1 protects vertebrate cells against spontaneous chromosome missegregation and is required to sustain anaphase delay when spindle function is disrupted by taxol(PMID:17276342). It has 3 isoforms produced by alternative splicing with the molecular mass of 54 kDa, 44 kDa and 50 kDa.

抗体的检测外，还应该用与其抗原成分相关的其它抗原进行交叉试验，方法可用ELISA、IFA法。例如：①制备抗黑色素瘤细胞的McAb，除用黑色素瘤细胞反应外，还应该用其它脏器的肿瘤细胞和正常细胞进行交叉反应，以便挑选肿瘤特异性或肿瘤相关抗原的单克隆抗体。②制备抗重组的细胞因子的单克隆抗体，应首先考虑是否与表达菌株的蛋白有交叉反应，其次是与其它细胞因子间有无交叉。 2．McAb的Ig类与亚类的鉴定 一般在用酶标或荧光素标记的第二抗体进行筛选时已经基本上确定了抗体的Ig类型
免疫系统受抗原刺激后，B细胞转化为浆细胞，由浆细胞产生与抗原发生特异性结合的球蛋白，这类球蛋白称为抗体(antibody,Ab)。 免疫球蛋白(immunoglobulim,Ig)是指具有抗体活性或化学结构与抗体相似的球蛋白。 免疫球蛋白普遍存在于哺乳动物和人类的血液、组织液和外分泌中。人体的免疫球蛋白主要有五类：IgM、IgA、IgG、IgD、IgE。 (一) 抗体结构 抗体是具有4条多肽链的对称
浓度很高。可见该法操作简便、经济，不过，腹水中常混有小鼠的各种杂蛋白（包括Ig），因此在很多情况下要提纯后才能使用，而且还有污染动物病毒的危险，故而最好用SPF级小鼠。（1）材料：a. 成年BALB/c小鼠。b. 降植烷（Pristane）或液体石蜡。c. 处于对数生长期的杂交瘤细胞。（2）方法：a. 腹腔接种降植烷或液体石蜡，每只小鼠0.3-0.5ml。b. 7-10天后腹腔接种用PBS或无血清培养基稀释的杂交瘤细胞，每只小鼠5×105/0.2ml。c. 间隔5天后，每天观察小鼠腹水产生情况，如腹部
