生物活性

IQ 1 is a Wnt/β-catenin/CBP signalling sustainer. IQ 1 maintains long-term expansion of Wnt/β-catenin-driven mouse embryonic stem cells (ESCs) and prevents spontaneous differentiation by enhancing β-catenin/CBP-mediated transcription and preventing conversion to β-catenin/p300-mediated transcription. IQ-1 regulates Wnt signalling by interacting with PR72/130. IQ 1 can be used in study of ESCs expansion.

体外研究(In Vitro)

IQ-1 (1.10, 3.48, 11.04 mM; 7 days) maintains the undifferentiated state of ESCs.
IQ-1 (0.28, 1.10, 2.76, 11.04 mM; 21 h) maintains murine ESC self-renewal independently of LIF.
IQ-1 Binds the PR72/130 Subunit of the Serine/Threonine Phosphatase PP2A in P19 cells.
IQ-1 (10 μM; 24 h) modulates Wnt signaling via interaction with PR72/130 in P19 cells.
IQ-1 (10 μM; 24 h) indirectly decreases the phosphorylation of p300 Ser-89 and Thereby the β-Catenin/p300 interaction.

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

Cell Viability Assay

Cell Line: Embryonic stem cells (ESCs)
Concentration: 1.10, 3.48, 11.04 mM
Incubation Time: 7 days
Result: Dose dependently increased alkaline phosphatase activity, in media containing 15% FCS without the addition of exogenous leukemia inhibitory factor (LIF).
Maintained SSEA-1 (undifferentiated ESC marker) expression dose-dependently.

RT-PCR

Cell Line: Embryonic stem cells (ESCs)
Concentration: 0.28, 1.10, 2.76, 11.04 mM
Incubation Time: 21 h
Result: Significantly increased and maintained Nanog expression in culture. (Nanog: a divergent homeoprotein pluripotency sustaining factor for ESCs that drives ESC self-renewal).
Exhibited the maintenance of murine ESC pluripotency were independent of the LIF/Stat3 pathway.

Western Blot Analysis

Cell Line: P19 cells
Concentration: 10 μM
Incubation Time: 24 h
Result: Significantly reduced coimmunoprecipitation of PR72/130 with both PP2A and Nkd.
Binded to PR72/130 subunit of PP2A, and disrupted the PP2A/Nkd complex.
Decreased the affinity of the β-catenin/p300 interaction and increases β-catenin/CBP usage by negatively regulating the phosphorylation of p300 Ser-89.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
