一般描述
最适pH是6-7
分子量： 128 kDa通过沉降速度扩散；133kDa通过光散射测量，而119.5 kDa通过电泳。
酪氨酸酶是一种含铜氧化酶，对儿茶酚和甲酚都具有活性。 它负责褐变反应。 该酶据报道有两个用于芳族底物的结合位点以及一个用于氧-铜的不同结合位点。 这里的铜很可能是Cu(I)，并包括涉及将其氧化至Cu(II)离子的失活。

The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How can Tyrosinase from mushroom, Product T3824, be dissolved and what is its expected stability in solution?
Tyrosinase can be dissolved in 50 mM potassium phosphate buffer at 2 mg/mL. Solutions are expected to retain activity for several days in the refrigerator (2-8°C) and for several weeks in the freezer (-20°C).
The website says Product T3824, Tyrosinase from mushroom, should be stored at -20°C, but I received it at room temperature. Is this correct?
The product is shipped at ambient temperature and is stable for up to two weeks during shipment. Once received, it is recommended to store the product at -20°C to insure the quality for long term storage.
I see that the approximate activity of Product T3824, Tyrosinase from mushroom, is ?1000 unit/mg solid, but how can I find the lot specific activity of this tyrosinase?
The certificate of analysis for the lot will report the exact tyrosinase activity for a particular batch. The lot number can be found on the label of the bottle, or you can call technical service (800-325-5832) for a sample lot number to view the online certificate of analysis.
I used to order another tyrosinase (Product No. T7755), which has since been discontinued. What is the difference between the replacement product T3824 and the discontinued product T7755?
The difference between these two products is that T3824 has been stabilized with trehalose, while T7755 was not.
