乳腺癌NY BR 85抗原抗体

简要描述:乳腺癌NY BR 85抗原抗体注意事项;This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. Function: Plays a central role in chromosome cohesion during mitosis by preventing premature dissociation of cohesin complex from centromeres after prophase, when most of cohesin complex dissociates from chromosomes arms. May act by preventing phosphorylation of the STAG2 subunit of cohesin complex at the centromere, ensuring cohesin persistence at centromere until cohesin cleavage by ESPL1/separase at anaphase. Essential for proper chromosome segregation during mitosis and this function requires interaction with PPP2R1A. Its phosphorylated form is necessary for chromosome congression and for the proper attachment of spindle microtubule to the kinetochore. Necessary for kinetochore localization of PLK1 and CENPF. May play a role in the tension sensing mechanism of the spindle-assembly checkpoint by regulating PLK1 kinetochore affinity. Isoform 3 plays a role in maintaining centriole cohesion involved in controlling spindle pole integrity.

实验流程:

(1)特异性结合抗原:抗体本身不能直接溶解或杀伤带有特异抗原的靶细胞,通常需要补体或吞噬细胞等共同发挥效应以清除病原微生物或导致病理损伤。然而,抗体可通过与病毒或毒素的特异性结合,直接发挥中和病毒的作用。

(2)活补体:IgM、IgG1、IgG2和IgG3可通过经典途径激活补体,凝聚的IgA、IgG4和IgE可通过替代途径激活补体。

(3)结合细胞:不同类别的免疫球蛋白,可结合不同种的细胞,参与免疫应答。

(4)可通过胎盘及粘膜:免疫球蛋白G(IgG)能通过胎盘进入胎儿血流中,使胎儿形成自然被动

免疫。免疫球蛋白A(IgA)可通过消化道及呼吸道粘膜,是粘膜局部抗感染免疫的主要因素。

(5)具有抗原性:抗体分子是一种蛋白质,也具有刺机体产生免疫应答的性能。不同的免疫球蛋白分子,各具有不同的抗原性。

(6)抗体对理化因子的抵抗力与一般球蛋白相同:不耐热,60~70℃即被破坏。各种酶及能使蛋白质凝固变性的物质,均能破坏抗体的作用。抗体可被中性盐类沉淀。在生产上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白,再经透析法将其纯化。

抗体的制备过程:

1.免疫原:普通的大分子蛋白,通过分子克隆构建载体并在大肠杆菌中进行诱导表达获得重组蛋白,纯化鉴定后可直接作为免疫原;小分子蛋白或化合物等分子量小,需要偶联载体对该分子进行改造才能使其成为具有免疫原性的抗原,常见偶联载体如BSA、OVA、HAS等。

2. 免疫动物:常用于制备抗血清的动物有豚鼠、家兔、鸡、大小鼠等,大量生产时需要用到狗、绵羊、山羊等。

3. 免疫血清的收集:一般家兔、绵羊、山羊可采用静动脉采血,家兔、豚鼠、大鼠、鸡可采用心脏采血,家兔、山羊、绵羊可采用静脉采血。

4. 乳腺癌NY BR 85抗原抗体免疫血清的纯化与鉴定:得到的抗血清需要进一步的纯化,利用偶联了抗原的亲和柱进行层析,具有高效,特异性强,纯度高的特定。接着要鉴定纯化蛋白的含量、相对分子的质量、纯度以及特异性。

5.免疫血清的保存:抗体一般比较稳定,在-80℃ ~-20 ℃可以保存约5年而不会影响效价,而真空干燥保存时间可以更久。保存前需经除菌并添加防腐剂。
