Human Galectin-9, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
- BackgroundGalectin-9 (LGALS9) is also known as tumor antigen HOM-HD-21 and ecalectin. Galectins are a family of proteins defined by their binding specificity for β-galactoside sugars, such as N-acetyllactosamine (Galβ1-3GlcNAc or Galβ1-4GlcNAc), which can be bound to proteins by either N-linked or O-linked glycosylation. As for Galectin-9, it has high affinity for the Forssman pentasaccharide, and it is also the ligand for HAVCR2/TIM3. Forthermore, Galectin-9 stimulates bactericidal activity in infected macrophages by causing macrophage activation and IL1B secretion which restricts intracellular bacterial growth.

**捷向您推荐美国Trevigen的一款通用PARP分析试剂盒检测试剂盒。该试剂盒是检测凋亡前与凋亡中细胞提取液中PARP活性的理想方案,操作简单,重复性高。其通过检测96孔板上生物素标记的多聚ADP核糖聚合到邻近组蛋白的反应,从而确定已知的或可能的PARP抑制剂。试剂盒中的依托泊苷(Etoposide)是拓扑异构酶Ⅱ抑制剂,在拓扑异构酶Ⅱ切割完DNA后能够稳定该酶。在试剂盒中,依托泊苷作为凋亡诱导的对照参与检测。
通量PARP/凋亡分析试剂盒可广泛应用于1)检测原代、肿瘤等细胞的PARP活性;2)检测凋亡前后的PARP活性;3)利用细胞裂解液筛选PARP抑制剂。
试剂盒特色比色法/化学发光法,无放射性输出。96well,高通量检测。极大地节省了分析时间,提高了使用效率。高敏感性。能够检测到500个细胞中低至0.1mU的PARP。检测范围广。0.1-10mU。样本用量少。仅仅需要10-100ng的提取物。检测时间短。仅需要3h即可完成检测。
**捷向您提供一站式的PARP相关实验解决方案,除了高通量PARP/凋亡分析试剂盒,还有PARP体内药理动力学二代分析试剂盒(PDAII)和通用PAPR分析试剂盒外(含组蛋白包被可拆卸板),以及相关抗体和重组蛋白。
Trevigen是一家快速成长的美国生物技术公司,专注于细胞凋亡、DNA损伤和修复、肿瘤细胞功能与行为等方面研究的肿瘤研究产品和服务。作为Trevigen在中国区域的总代理,**捷与Trevigen一道为中国的科研工作者提供最好、最新的氧化应激、细胞损伤和肿瘤细胞行为研究等领域内的优质产品和技术服务。如果您对上述产品及方案感兴趣,请致电400-6800-868至**捷科技有限公司垂询血管生成研究的相关实验解决方案,或索取最新的产品资料。
A.优点:
多重分析——一次分析可以检测16种干细胞相关的TF
定量比较——二个样本的差异可以定量分析和比较
步骤简单——探针温育、柱分离、板杂交和HRP检测
无需贵重仪器——无需如Luminex那样的贵重仪器
B.原理:
干细胞转录因子活性多重检测阵列试剂用于同时检测多种TF活性。该技术中,基于TFDNA结合位点的一致性序列,制备一系列生物素标记的探针。当探针混合物与核提取物一起温育时,每个探针寻找相应的TF,形成TF/探针复合物,通过柱离心纯化可以很容易与游离探针分开。结合的探针从混合物中分离出来,通过板杂交分析。板孔中预包被上与探针互补的特异序列,捕获的DNA探针进一步用链酶亲和素-HRP检测,化学发光检测仪测定发光强度(RLUs)。
