PINT-87aa

PINT-87aa;

PINT-87aa 是一种 87 个氨基酸的肽,由长的基因间非蛋白质编码 RNA p53 诱导的转录本 (LINC-PINT) 的环状形式编码。PINT-87aa 可直接与聚合酶相关因子复合物 (PAF1c) 相互作用并抑制多种癌基因的转录延伸。PINT-87aa 在体外和体内抑制胶质母细胞瘤细胞增殖。

生物活性

PINT-87aa, an 87-amino acid (aa) peptide, is encoded by the circular form of the long intergenic non-protein-coding RNA p53-induced transcript (LINC-PINT). PINT-87aa directly interacts with polymerase associated factor complex (PAF1c) and inhibits the transcriptional elongation of multiple oncogenes. PINT-87aa suppresses glioblastoma cell proliferation in vitro and in vivo[1].

体外研究
(In Vitro)

Both 456 and 4121 cells overexpressing PINT-87aa exhibits G1 arrest and reduces cell proliferation without obvious cellular toxicity, whereas PINT-87aa K.O. SW1783 and Hs683 cells shows increased cell cycle and cell proliferation rates[1].
The mRNA of PAF1 downstream genes (CPEB1, SOX-2, c-Myc, etc.) is inhibited transcriptionally in PIN87aa-overexpressing 456 and 4121 cells compared with that in control cells[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

456 and 4121 cells stably overexpressing PINT-87aa exhibits decreased in situ tumorigenic potential compared with control cells, as assessed by tumor growth and animal survival in mice[1].
PINT-87aa K.O. cells results in significantly increased xenograft tumor volumes of nude mice[1].

腺相关病毒纯化方案——Cell Biolabs的AAV纯化试剂盒

腺相关病毒(Adeno-Associated Virus, AAV)作为基因治疗的载体存在一些非常突出的优点,比如能感染分裂和非分裂细胞、不具有明显的致病性、整合至宿主特定染色体长期表达目的蛋白等,已成为基因治疗被广泛应用的安全、有效的载体。

AAV病毒纯化的传统方法是加热失活法和平衡密度梯度离心法。目前大多数腺相关病毒都来源于AAV-2血清型腺病毒。对于AAV-2而言,由于其表面存在细胞表面受体,能有效结合到某些蛋白上,所以能使用亲和层析法纯化,因此也就避免了CsCl2和辅助包装病毒的污腺相关病毒纯化方案——Cell Biolabs的AAV纯化试剂盒染。这些细胞表面受体包括硫酸乙酰酣素糖蛋白受体、联合辅助受体等,如使用肝素亲和层析方案进行腺相关病毒,但是这种方案需要对纯化前的病毒液进行预处理。因此这些方法在具体的运用时都存在一定的缺陷,如单一的CsCl2超速离心较为耗时,而且纯度上也不是很高,而肝素亲和层析以及进行的预处理,在经济性和时效性方面尚有不足。

Cell BioLabs为您提供了新型高效的腺相关病毒提取纯化方案,ViraBind™ AAV Purification Kits试剂盒(货号:VPK-140)采用特殊的专利Matrix技术,该纯化Matrix胶能特异性吸附腺相关病毒颗粒,大大减少试验时间的同时还保证了腺相关病毒的纯化度。后继采用常规离心的方式(较大10,000g x10min),整个过程只需3个小时,回收率高达60%。

ViraBind™ AAV Purification Kit每次能处理一个150mm培养皿或两个100mm大小培养皿内的病毒感染细胞液,并获得100ul的高纯度腺相关病毒液。每个Kit可完成10次纯化,经SDS验证无杂蛋白条带,具有较高的感染滴度。获得的腺相关病毒感染原代细胞有非常好的效果。

另外针对一些需要腺相关病毒大量提取的用户,Cell Biolabs还提供了AAV的大提试剂盒ViraBind™ AAV Purification Mega Kit(货号:VPK-141/VPK-141-5),在具体的纯化后继步骤中,使用透析柱装置,每次可进行10个150mm培养皿大小的病毒感染细胞的提纯,分2次大提和10次大提两个包装。 

产品名称 货号 产品说明(点击查看说明书)
ViraBind™ AAV Purification Kit VPK-140 10次纯化,每次2个10cm板细胞
ViraBind™ AAV Purification Mega Kit VPK-141 2次纯化,每次10个15cm板细胞
VPK-141-5 10次纯化,每次10个15cm板细胞

 美国著名细胞学试剂专家Cell BioLabs为您提供高效简便的重组腺病毒相关产品和服务,产品包括腺相关病毒的纯化、定量和高效转染试剂。ViraBind™腺相关病毒纯化试剂盒采用特殊的纯化Matrix技术,无需超速离心,在大大减少试验时间的同时还保证了腺相关病毒的纯化度。QuickTiter™腺相关病毒定量试剂盒通过检测腺病毒DNA含量来测定其病毒含量,只需2小时。ViraDuction™腺相关病毒转染试能极大的增加腺相关病毒在多种细胞内的转染效率,包括传统转染方法转导较低的细胞非分裂细胞,如原代培养细胞和干细胞。如果您对腺相关病毒产品或者腺病毒、慢病毒以及逆转录病毒产品感兴趣,请致电021-50837765到上海金畔生物科技有限公司垂询腺相关病毒相关的实验解决方案,或索取最新的Cell BioLabs产品资料。
