半乳糖氧化酶 9028-79-9

活力：≥30units/mg protein

活力定义：one unit equals a change in absorbance at 425nm of 1.0 per minute at 25℃,pH6.0 using a perosidase/o-tolidine coupled assay with galactose as the substrate
最佳PH：7.0

产品描述：Supplied as a purified powder,containing sodium phosphate and cucrose as stablilizer.Oxdizes galactose and some galactose derivatives in both free and polymeric forms.Oxidation at the C6 position.
性状：粉末，是由一条含639个氨基酸基团的单聚肽链组成、以铜原子为活性中心的酶。非蓝氧化酶的一种，是一种含铜不显蓝色的酶。与蓝铜氧化酶不一样，在600nm附近吸收系数很小，可用电子自旋共振（ESR）谱监测，其光谱特征与无机铜配位化合物相似
用途：生化研究。催化氧化半乳糖，确定样品中半乳糖的含量
