產品介紹

分子量:約128 KDa 。

活力定義:One unit causes an increase in the absorbance at 280nm of 0.001 per minute at 25℃,PH 6.5,using L-tryosine as substrate.

適宜溫度25℃。

最佳PH:6.0~7.0。

性狀:粉末。

介紹:可催化含酚基化合物(如酪氨酸、酚類化合物等)氧化成醌的酶。此類酶廣泛存在于自然界,植物中分布很廣,如馬鈴薯、茶葉、漆樹乳汁中含量相當高。高等動物的皮膚、毛發、角膜中的黑色素也是由于此酶氧化酪氨酸所生成的產物。蘑菇等菌類及其他微生物中也產生此類酶。通常從野蘑菇中提取,系生物催化劑之一,含有銅離子的蛋白質。等電點<5.0;含氮量約13.6%。含銅量約0.25%。紫外吸收峰在273nm和330nm處。

溶解性: 產品可以用水或者緩沖液溶解,建議現配現用,用不完部分盡量4℃儲存,盡快使用。溶液形式不能凍融,凍融會導致失活。
儲存條件: -20℃
用途: 它催化酪氨酸氧化成多巴和多巴進一步氧化成能產生黑色素的前體物——多巴醌。
