β-Sheet Breaker Peptide iAβ5
CAS No. : 182912-74-9
MCE 国际站:β-Sheet Breaker Peptide iAβ5
产品活性:β-Sheet Breaker Peptide iAβ5 是一种有效的脑淀粉样蛋白-β (Abeta) 降解剂。Abeta 沉积与阿尔茨海默病 (AD) 相关,相关毒性来自于它的 β 折叠构象和聚集。β-Sheet Breaker Peptide iAβ5 可重复诱导体内纤维状淀粉样沉积物的分解。因此,β-Sheet Breaker Peptide iAβ5 可防止和/或逆转由 Abeta 引起的神经元收缩,并减少 Abeta 沉积物周围白细胞介素 IL-1beta 阳性小胶质细胞样细胞的范围。β-Sheet Breaker Peptide iAβ5 可减少 AD 中大脑淀粉样斑块的大小和/或数量。β-Sheet Breaker Peptide iAβ5 由疏水性苯甲醇 (HBA) 标签标记,在酸性条件下呈鲜艳的蓝色,可用于定量测定。
研究领域:Neuronal Signaling
作用靶点:Amyloid-β
In Vitro: β-Sheet Breaker Peptide iAβ5 (1.5 μg/μL; 7 days) incubates with Aβ1-42 (0.5 μg/μL) for 7 days, inhibits amyloid βprotein fibrillogenesis, disassembles preformed fibrils in vitro and prevents neuronal death induced by fibrils in cell culture.
β-Sheet Breaker Peptide iAβ5 (60 μM; 48 h) shows insignificant cytotoxicity in human neuroblastoma (IMR-32) cell treated with 50 μM aggregated Aβ1-42 for 2 days.
In Vivo: β-Sheet Breaker Peptide iAβ5 (100 nmol/rat; Intra-amygdala injection; 7 days) coinjected with Aβ1-42 (5 nmol) into in the rat amygdala, blocks Aβ1-42 neurotoxicity in tissue culture, and amyloid fibril formation in the rat model.
β-Sheet Breaker Peptide iAβ5 (100 nmol/rat, 200 nmol/rat; Intra-amygdaloid injection; 7 days) followed by Aβ1-42 (5 nmol), induces disassembly of pre-existing Aβ fibrils in vivo, and leads to a reversal or prevention of Aβ-induced histopathological changes in rat model.

【求助】关于β-catenin和细胞增殖的关系,急死了!!!
rainbubu 想研究β-catenin在某肿瘤中和细胞增殖和预后的关系,材料用存档的蜡块和冰冻,想用免疫组化来检测β-catenin的表达情况,然后想检测β-catenin的表达和细胞增殖的关系,能不能简单的看β-catenin和PCNA、ki-67之间的关系,有统计学意义就得出β-catenin和细胞增殖有相关性。 但是也不能说明细胞增殖就是β-catenin表达异常的结果啊 那么怎么才能说明β-catenin和细胞增殖的关系
