Protease-Activated Receptor-1, PAR-1 Agonist TFA

生物活性

Protease-Activated Receptor-1, PAR-1 Agonist is a selective proteinase-activated receptor1 (PAR-1) agonist peptide. Protease-Activated Receptor-1, PAR-1 Agonist corresponds to PAR1 tethered ligand and which can selectively mimic theactions of thrombin via this receptor[1][2].

IC50 Target

PAR-1[1]

体外研究
(In Vitro)

Protease-Activated Receptor-1, PAR-1 Agonist induces activation of protein kinase C isoenzymes alpha and epsilon in human HT-29 colon carcinoma cells expressing PAR1 endogeneously. On the cellular level, Protease-Activated Receptor-1, PAR-1 Agonist and thrombin prompted HT-29 cell migration and matrix adhesion by a PKCepsilon-dependent mechanism as concluded because of the inhibition of PAR1-mediated effects by the PKC inhibitor bisindolylmaleimide I and the PKCepsilon translocation inhibitory peptide EAVSLKPT but not by the PKC inhibitor Gö 6976[2].

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

概要·使用例

概要

本产品是由水合物凝胶通过300℃~500℃脱水制成的。

因为对水,气体等具有吸附能力,所以被用作吸附剂,干燥剂,催化剂(特别是脱水催化剂)。

另外,活性氧化铝分成三类,分别是酸性(pH4),碱性(pH9),中性(pH7.5)。本产品属于碱性类。

【柱色谱法用产品】【吸附色谱】【柱色谱载体】柱色谱法(column chromatography)常用于中到大规模的制备以及纯化中。

我们公司为客户提供了各种底物载体,修饰载体等多种类产品,它不仅可用于分离有机化合物,还包括天然产物,生物聚合物等。


用于吸附·反相色谱法的氧化铝载体

适用于分离中性·碱性物质,被广泛用于生物碱,类固醇,醛酮,芳香烃。

另外,吸附性载体根据其含有的水分,活性度会有显著变化。

【色谱用产品】【柱色谱载体】【用于吸附・反向色谱法的载体】【氧化铝】


氧化铝的特性

活性氧化铝因其活性具有很高的分离能力,多用于色谱法的领域中。另外,它不会与常见的溶剂发生反应,也几乎不与溶质发生反应。它的活性度会根据其水分含量发生阶段性变化,可以调节溶质的吸附能力。

氧化铝的活性度是根据偶氮染料(产品编号:012-01661 Alumina B-Tester使用)的保持能力而分成5个阶段。


(Brockmann的活性度)

以活性度I为基础,根据水分的添加,被划分为活性度II, III, IV, V的活性度(吸附能力)会逐渐降低。

中性氧化铝0%3%6%10%15%Water addition

碱性氧化铝0%3%6%10%15%Water addition

※酸性氧化铝适用于分离酸性物质(酸性肽等),中性氧化铝可用于儿茶酚胺等的预处理载体。

碱性氧化铝被广泛用于生物碱,类固醇,萜等应用领域。

使用法

用于预处理的氧化铝的提纯法

儿茶酚胺分析预处理中会使用氧化铝,如果存在杂质会使儿茶酚胺的回收率降低。

我们公司为顾客提供了用于儿茶酚胺分析预处理的活性氧化铝(产品编号:018-09561)

我们介绍利用Anton&Sayre法的普通提纯法,以供参考。
