Catalog Number:  26468

Gene Symbol:  H-Ras; K-Ras; N-Ras

Description:  Anti-RAS (K117N) Mouse Monoclonal Antibody

Background:  The K117N mutation of KRas results in an amino acid substitution at position 146, from an alanine to a threonine. KRAS encodes a protein that is a member of the small GTPase superfamily. Ras K117N mutation results in decreased GTPase activity and constitutive signaling. It can be found in many tumors, such as lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma.

Immunogen:  A synthetic peptide from the internal region of Ras which includes the mutation of K117N, human origin.

Applications:  ELISA, WB, IHC

Recommended Dilutions:   ELISA:1:1000-1:5000 WB: 1:500-1:1000 IHC: 1:50-1:100

定制肽合成NewEast Biosciences为全球生物研究界提供高质量的粗制和纯化肽或拟肽。我们使用先进的自动，半自动和手动合成器以及Fmoc技术合成肽。肽酰胺键通过HOAT / HATU偶联形成。我们的肽通过制备型HPLC纯化，并且每个级分均通过使用不同溶剂系统的分析型HPLC进行进一步分析。收集并冻干仅通过质谱法验证的具有单个峰的级分。肽通常在1-2周内递送。粗肽也可以大量节省（参见价格表）。周转时间为5-7天。除了正常的肽合成外，我们还合成修饰的肽和多种抗原性肽（MAPs）。修饰在C末端，N末端和内部残基处进行。在C末端，氨基可与羧酸，异氰酸酯和磺酰氯反应形成酰胺，脲和磺酰胺。在此终端进行经典的生物素化，荧光标记和脂质化。这些修饰以及磷酸化和糖基化也可以在内部残基处进行。相反，在C末端的修饰非常具有挑战性，需要溶液阶段的干预。为了在C端进行修饰，必须将肽从树脂中释放出来。然后，用相应的化学方法修饰释放的肽。但是，我们已经开发了适当的化学方法，可以在固相的C末端引入生物素，荧光染料和胺。随着化学，我们降低了合成肽以及昂贵试剂的成本。作为NewEast的客户，我们将节省下来的钱转嫁给您。
