产品介绍 DNA helicase involved in cellular proliferation. Possesses DNA-dependent ATPase and helicase activities. This helicase translocates on single-stranded DNA in the 5' to 3' direction in the presence of ATP and, to a lesser extent, dATP. Its unwinding activity requires a 5'-single-stranded region for helicase loading, since flush-ended duplex structures do not support unwinding. The helicase activity is capable of displacing duplex regions up to 100 bp, which can be extended to 500 bp by RPA or the cohesion establishment factor, the Ctf18-RFC (replication factor C) complex activities. Stimulates the flap endonuclease activity of FEN1. Required for normal sister chromatid cohesion. Required for recruitement of bovine papillomavirus type 1 regulatory protein E2 to mitotic chrmosomes and for viral genome maintenance. Required for maintaining the chromosome segregation and is essential for embryonic development and the prevention of aneuploidy. May function during either S, G2, or M phase of the cell cycle. Binds to both single- and double-stranded DNA.
Tissue specificity: Highly expressed in spleen, B-cells, thymus, testis, ovary, small intestine, and pancreas. Very low expression seen in the brain. Expressed in dividing cells and/or cells undergoing high levels of recombination. No expression is seen in cells signaled to terminally differentiate. Expressed in keratinocyte growth factor-stimulated cells but not in serum, EGF and IL1-beta-treated keratinocytes.

Subunit : Interacts with the CTF18-RFC complex, PCNA and FEN1. Forms a complex with RAD21, SMC1 and SMC3. Interacts with bovine papillomavirus type 1 regulatory protein E2.
Subcellular Location : Nucleus. Nucleus, nucleolus. Note=During the early stages of mitosis, localizes to condensed chromatin and is released from the chromatin with progression to metaphase. Also localizes to the spindle poles throughout mitosis and at the midbody at later stages of mitosis (metaphase to telophase). Co-localizes with bovine papillomavirus type 1 regulatory protein E2 at early stages of mitosis.
Tissue Specificity : Highly expressed in spleen, B-cells, thymus, testis, ovary, small intestine, and pancreas. Very low expression seen in the brain. Expressed in dividing cells and/or cells undergoing high levels of recombination. No expression is seen in cells signaled to terminally differentiate. Expressed in keratinocyte growth factor-stimulated cells but not in serum, EGF and IL1-beta-treated keratinocytes.
DISEASE : Defects in DDX11 are the cause of Warsaw breakage syndrome (WBRS) [MIM:613398]. It is a syndrome characterized by severe microcephaly, pre- and postnatal growth retardation, facial dysmorphism and abnormal skin pigmentation. Additional features include high arched palate, coloboma of the right optic disk, deafness, ventricular septal defect, toes and fingers abnormalities. At cellular level, drug-induced chromosomal breakage, a feature of Fanconi anemia, and sister chromatid cohesion defects, a feature of Roberts syndrome, coexist.
Similarity : Belongs to the DEAD box helicase family. DEAH subfamily. DDX11/CHL1 sub-subfamily.
Contains 1 helicase ATP-binding domain.

实验原理 :
（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。

抗体的鉴定：
1）抗体的效价鉴定：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。
3）真核翻译起始因子2C2抗体的亲和力：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。
