It rained and dredged the wind last night. I worked overtime to improve the steps. I asked the researcher, but the result was the same. "Do you know? Do you know? It only makes people lose weight." In the face of heavy and arduous R&D tasks, how to choose the right enzyme preparation? How to maximize the effectiveness of raw materials? These problems have plagued countless people. If you learn to read the instructions of enzyme preparations correctly, perhaps these problems will be solved.
1. Understand the color of enzyme powder
In vitro diagnostic reagents will be marked with the color of the liquid reagent when they are registered. The color of enzyme preparations will affect the color of reagents after feeding; for example, COX, FPOX, SOX, etc. are all light yellow or yellow powders, and most of the reagents prepared are also light yellow or yellow. It is important to choose an enzyme preparation with an appearance color similar to the registration information. It is not only necessary to carefully check the packaging before feeding, but also to check whether the appearance of the enzyme preparation powder is consistent with the description in the instructions.
2. Understand the specific activity parameters of enzyme preparations
When calculating the feeding amount, the specific activity is a parameter that must be understood, and the feeding amount can be determined after conversion. In addition, specific activity is also an important parameter for comparing enzyme preparations. The enzyme preparation itself is a protein powder, which can be used as a nutrient for the growth of microorganisms, which will introduce pollution. Choosing enzyme preparations with high specific activity can reduce the amount of feed, reduce the problem of microbial contamination, increase the shelf life of diagnostic reagent products, and improve product quality.
3. Understand the pH range of enzyme preparations
People have their own comfort zone. They don't like severe cold or intense heat. They like to breathe freely in the fresh air. The same is true for enzyme preparations. Each enzyme preparation has its own optimum range. Only at a certain pH and temperature can the enzyme preparation be stimulated to maximize its catalytic activity. Find the optimum pH value from the instructions, and then set the pH value of the reagent within this range, so that the enzyme molecule can work in the best state.
4.understand the interfered substances of enzyme preparations
The activity of enzyme preparations will also be interfered by the required substances, such as metal ions such as Ag+, Hg2+, Fe3+, etc. The instructions will also list common interfering substances, which is convenient for production personnel to avoid the introduction of such substances during the development and production of reagents. Enzyme activity.
The above important information can be found in the "Enzyme Preparation Manual". As a professional manufacturer of enzyme preparations, Desheng Technology can not only provide enzyme preparation raw materials comparable to imported brands, but also has diagnostic reagent development experience and can provide Mature diagnostic reagent products.
