The enzyme consists of a protein component with reverse transcriptase activity, encoded by this gene, and an RNA component which serves as a template for the telomere repeat. Telomerase expression plays a role in cellular senescence, as it is normally repressed in postnatal somatic cells resulting in progressive shortening of telomeres. Deregulation of telomerase expression in somatic cells may be involved in oncogenesis. Studies in mouse suggest that telomerase also participates in chromosomal repair, since de novo synthesis of telomere repeats may occur at double-stranded breaks. Alternatively spliced variants encoding different isoforms of telomerase reverse transcriptase have been identified; the full-length sequence of some variants has not been determined. Alternative splicing at this locus is thought to be one mechanism of regulation of telomerase activity. [provided by RefSeq, Jul 2008].Function :Telomerase is a ribonucleoprotein enzyme essential for the replication of chromosome termini in most eukaryotes. Active in progenitor and cancer cells. Inactive, or very low activity, in normal somatic cells. Catalytic component of the teleromerase holoenzyme complex whose main activity is the elongation of telomeres by acting as a reverse transcriptase that adds simple sequence repeats to chromosome ends by copying a template sequence within the RNA component of the enzyme. Catalyzes the RNA-dependent extension of 3'-chromosomal termini with the 6-nucleotide telomeric repeat unit, 5'-TTAGGG-3'. The catalytic cycle involves primer binding, primer extension and release of product once the template boundary has been reached or nascent product translocation followed by further extension. More active on substrates containing 2 or 3 telomeric repeats. Telomerase activity is regulated by a number of factors including telomerase complex-associated proteins, chaperones and polypeptide modifiers. Modulates Wnt signaling. Plays important roles in aging and antiapoptosis. 端粒酶相关蛋白2/端粒酶逆转录酶抗体说明书抗体的生物素化标记实验要点:1.如在反应混合液中有叠氮钠或游离氨基存在,会YZ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Z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。端粒酶相关蛋白2/端粒酶逆转录酶抗体说明书抗体的鉴定:1)抗体的效价鉴定:不管是用于诊断还是用于ZL,制备抗体的目的都是要求较GX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YZ试验测定。以不同浓度抗原和近似抗原分别做竞争YZ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。Baird-Parker琼脂基础24040250g用于凝固酶阳性葡萄球菌的选择性分离培养和计数(GB4789.02和化妆品卫生规范微...HYLB Broth 培养基 100g incubation media HYLB Broth 培养基 100g牙龈卟啉单胞菌 产氯霉素 支/瓶PSB(磷酸盐缓冲液pH7.2)9ml*20支/包用于样品的稀释美蓝(亚甲基蓝) 25 炭疽杆菌检测用配套试剂端粒酶相关蛋白2/端粒酶逆转录酶抗体说明书BufferedListeriaEnrichmentBroth菌种培养基 Strain Medium(for B.Cereus) 用于四环素检定中蜡样芽孢杆菌的培养(SN标准)聚山梨酯80培养基(需氧、厌氧菌) Tween80 Medium(Bacteria) 250克 油剂的无菌试验小川氏培养基250g/瓶用于结核杆菌的药敏试验,也可用于结核杆菌的分离和培养,需添加甘油和全蛋液incubationmedia小川氏培养基250g/瓶用于结核杆菌的药敏试验,也可用于结核杆菌的分离和培养,需添加甘油和全端粒酶相关蛋白2/端粒酶逆转录酶抗体说明书技术外包服务:★分子生物学:质粒抽提、PCR、Q-PCR、RT-PCR、分子生物学:基因合成、引物合成、基因测序、载体构建等★蛋白工程:原核、哺乳动物蛋白表达系统等★病毒包装:腺病毒、慢病毒等★抗体工程:磁珠分选、病理染色、WB、ELISA、IP、IF、IHC、FACS、Confocal等等★细胞工程:细胞表型分析(凋亡、增殖、周期、迁移、侵袭、修复、克隆形成)、细胞培养、细胞膜制备、稳定细胞株构建、细胞RNAi技术等等。
