产品详情
Malantide 是一种合成的十二肽,由被磷酸化酶激酶β亚基上的 PKA 磷酸化的位点衍生而来。Malantide 是 PKA 的高度特异性底物,Km 为 15 μM,并且在各种大鼠组织提取物中显示出 PKI 抑制 > 90%底物磷酸化。Malantide 也是 PKC 的有效底物,Km 为 16 μM。
生物活性
Malantide is a synthetic dodecapeptide derived from the site phosphorylated by cAMP-dependent protein kinase (PKA) on the β-subunit of phosphorylase kinase. Malantide is a highly specific substrate for PKA with a K m of 15 μM and shows protein inhibitor (PKI) inhibition >90% substrate phosphorylation in various rat tissue extracts. Malantide is also an efficient substrate for PKC with a K m of 16 μM.

Km: 15 μM (PKA), 16 μM (PKC), 233 μM (PKG)
体外研究(In Vitro)
The Km values of Malantide are 15 μM and 223 μM for PKA and PKG, respectively. The Vmax values are 23.8 units/mg and 6.6 units/mg for for PKA and PKG, respectively.
A statistically significant effect of isoprenaline on the activity ratio of guinea-pig heart was only: observed with Malantide. has not independently confirmed the accuracy of these methods. They are for reference only.

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。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
