产品介绍 Separase is a cysteine protease that is essential for mitotic progression by separating sister chromatids. Each cell must receive one chromatid of every chromosome, during mitosis. Cohesin plays an important role in cohering sister chromatids during the prophase through anaphase stages of mitosis, making certain that genomic information is replicated accurately. As the cellular division process continues, separase destroys cohesin by means of cleavage, allowing the chromatids to separate and divide with the cell. Separase activity is highly regulated. It not only cleaves cohesin at the onset of anaphase but also cleaves itself, promoting downregulation of separase after anaphase. Should a human cell become an aneuploid (one too many or too few chromatids), the embryo most likely will not survive. Should the embryo survive, it will most likely develop severe birth defects or later develop malignant cancers.
Function : Caspase-like protease, which plays a central role in the chromosome segregation by cleaving the SCC1/RAD21 subunit of the cohesin complex at the onset of anaphase. During most of the cell cycle, it is inactivated by different mechanisms.
Subunit : Interacts with PTTG1. Interacts with RAD21.
Subcellular Location : Cytoplasmic and Nuclear
Post-translational modifications : Autocleaves. This function, which is not essential for its protease activity, is unknown.
Phosphorylated by CDK1. There are 8 Ser/Thr phosphorylation sites. Among them, Ser-1126 phosphorylation is the major site, which conducts to the enzyme inactivation.
Similarity : Belongs to the peptidase C50 family.

抗体的生物素化标记实验要点:
1. 外纺锤体极样蛋白1抗体规格 如在反应混合液中有叠氮钠或游离氨基存在,会抑制标记反应。因此,蛋白质在反应前要对 0.1mol/L碳酸氢钠缓冲液或0.5mol/L硼酸缓冲液充分透析;
2.所用的NHSB及待生物素化蛋白质之间的分子比按蛋白质表面的ε-氨基的密度会有所不同,选择不当则影响标记的效率,应先用几个不同的分子比来筛选最适条件;
3.用NHSB量过量也是不利的,抗原的结合位点可能因此被封闭,导致抗体失活;
4.由于抗体的氨基不易接近可能造成生物素化不足,此时可加入去污剂如 Triton x-100, Tween20等;
5.当游离ε-氨基(赖氨酸残基的氨基)存在于抗体的抗原结合位点时,或位于酶的催化位点时,生物素化会降低或损伤抗体蛋白的结合力或活性;
6.生物素还可能与不同的功能基团,如羰基、氨基、巯基、异咪唑基及苯酚基,也可与糖基共价结合;
7.交联反应后,应充分透析,否则,残余的生物素会对生物素化抗体与亲和素的结合产生竞争作用;
8.在细胞的荧光标记实验中,中和亲和素的本底低,但由于链霉亲和素含有少量正电荷,故对某些细胞可导致高本底。
抗体的鉴定:
1)外纺锤体极样蛋白1抗体规格 抗体的效价鉴定:不管是用于诊断还是用于,制备抗体的目的都是要求较高效价。不同的抗原制备的抗体,要求的效价不一。鉴定效价的方法很多,包括有试管凝集反应,琼脂扩散试验,酶联免疫吸附试验等。常用的抗原所制备的抗体一般都有约成的鉴定效价的方法,以资比较。如制备抗抗体的效价,一般就采用琼脂扩散试验来鉴定。
2)抗体的特异性鉴定:抗体的特异性是指与相应抗原或近似抗原物质的识别能力。抗体的特异性高,它的识别能力就强。衡量特异性通常以交叉反应率来表示。交叉反应率可用竞争抑制试验测定。以不同浓度抗原和近似抗原分别做竞争抑制曲线,计算各自的结合率,求出各自在IC50时的浓度,并按公式计算交叉反应率。
如果所用抗原浓度IC50浓度为pg/管,而一些近似抗原物质的IC50浓度几乎是无穷大时,表示这一抗血清与其他抗原物质的交叉反应率近似为0,即该血清的特异性较好。
3)抗体亲和力:是指抗体和抗原结合的牢固程度。亲和力的高低是由抗原分子的大小,抗体分子的结合位点与抗原决定簇之间立体构型的合适度决定的。有助于维持抗原抗体复合物稳定的分子间力有氢键,疏水键,侧链相反电荷基因的库仑力,范德华力和空间斥力。亲和力常以亲和常数K表示,K的单位是L/mol。抗体亲和力的测定对抗体的筛选,确定抗体的用途,验证抗体的均一性等均有重要意义。
