碱性磷酸酶活性染料是一款干细胞成像产品,允许使用者对多能干细胞(PSC)进行区别性染色。该染料是碱性磷酸酶(alkaline phosphatase,AP)一种荧光底物,具有细胞渗透性,对细胞无毒性,两个小时即完成扩散。碱性磷酸酶活性染料由 DMSO 中的 50 µL 500X 荧光素染料组成,足够用于染色两块 24 孔板、四块 6 cm 培养皿或两块 10 cm 培养皿。
该碱性磷酸酶活性染料能够让您:
• 识别多能干细胞,具有高于背景荧光的强荧光信号
• 通常在 20 分钟或更短时间内就能完成 PSC 染色
• 使用第一种市售的能维持细胞活力的碱性磷酸酶染色剂
碱性磷酸酶多能干细胞检测方法
AP 是 PSC 的表型标志物,包括未分化的胚胎干细胞 (ESC)、诱导多能干细胞 (iPSC) 和胚胎生殖细胞 (EGC)。AP 在大多数细胞类型中都有表达,但在 PSC 中其表达量大幅增加。因此,AP 染色可用于区别性染色 PSC,以便轻松将其与用作饲养层的小鼠胚胎成纤维细胞 (MEF) 和通常用于重编程实验的亲代成纤维细胞进行区分。
在不牺牲珍贵的集落的情况下进行多能性筛选
碱性磷酸酶活性染料能够维持干细胞活力,是在重编程工作流程早期筛选集落的理想选择。它也可以在后期用作阴性选择工具,用于识别未分化细胞。
细胞快速染色
碱性磷酸酶活性染料使用一种简单、非永久性、保持细胞活力的方案来识别您的实验中的 PSC。只需将染料稀释在培养基中,涂抹于细胞,轻轻清洗,细胞即可用于荧光成像。
仅供研究使用。不可用于诊断程序。

文献和实验
Characterization of pluripotent stem cells is required for the registration of stem cell lines and allows for an impartial and objective comparison of the results obtained when generating multiple lines. It is therefore crucial to establish specific, fast and reliable protocols to detect the hallmarks of pluripotency. Such protocols should include immunocytochemistry (takes 2 d), identification of the three germ layers in in vitro-derived embryoid bodies by immunocytochemistry (immunodetection takes 3 d) and detection of differentiation markers in in vivo-generated teratomas by immunohistochemistry (differentiation marker detection takes 4 d). Standardization of the immunodetection protocols used ensures minimum variations owing to the source, the animal species, the endogenous fluorescence or the inability to collect large amounts of cells, thereby yielding results as fast as possible w
Lung epithelial cells play critical roles in initiating and modulating immune responses during pulmonary infection or injury. To better understand the spectrum of immune response-related proteins present in lung epithelial cells, we developed an improved method of isolating highly pure primary murine alveolar type (AT) II cells and murine tracheal epithelial cells (mTECs) using negative selection for a variety of lineage markers and positive selection for epithelial cell adhesion molecule (EpCAM), a pan-epithelial cell marker. This method yielded 2-3?×?10(6) ATII cells/mouse lung and 1-2?×?10(4) mTECs/trachea that were highly pure (>98%) and viable (>98%). Using these preparations, we found that both ATII cells and mTECs expressed the Lyn tyrosine
