In 1911, Germany used acetaldehyde oxidation method to create the world's first synthetic acetic acid plant. In 1966 Monsanto, the United States developed the methanol low-pressure carbonylation process (built in 1970), which has become the main method of synthesizing acetic acid, accounting for ...

产品描述Exenatide is a medication used to treat diabetes mellitus type 2. Exenatide binds to the intact human Glucagon-like peptide-1 receptor (GLP-1R) in a similar way to the human peptide glucagon-like peptide-1 (GLP-1); exenatide bears a 50% amino acid homology to GLP-1 and it has...
(pKa=4.76) and acetate in a buffer solution of 0.15 M at pH 4.5 ? Buffer Solution:In chemistry, it is obtained when two compounds, one is a weak base (acetic acid), and its conjugate (acetate), is adding in an aqueous solution. The pH value...
不同体系分离蛋白质的特性与Glycine和Tricine的pKa值有关,不同大小的蛋白质在不同的缓冲体系中拥有不同的电泳迁移率,且特定范围内的蛋白质分辨率较高。因此,如果需要分离大分子量蛋白,就需要选择合适的电泳系统。同时,也建议使用由下至上丙烯酰胺浓度降低的梯度胶。目前研究中常用Tris-Acetate凝胶系统分离大分子量蛋白...
