Two-dimensional electrophoresis: cleaning the IEF tube
1. After IEF, thoroughly clean the tube with deionized water. 2. Heat 500ml 0.6% Deconex solution to 60~80°C. 3. Immerse the glass tube in the Deconex solution and place it at 70°C for 3 times for 10 minutes: After every 10 minutes, remove the glass tube with tweezers, pour out the cleaning solut...Read more -
How to prove the existence of the edge of the small hole
[Principle] Stomatal transpiration is the main way for plants to lose water. The stomata are very small, and their total area generally does not exceed 1% of the leaf area. However, the water lost by the leaf through stomata transpiration reaches 50 80% of the free surface equal to the leaf area....Read more -

PH meter and beaker
“The pH meter is an instrument for measuring the pH of a solution. The main body of the pH meter is a precision potentiometer. When measuring, insert the composite electrode into the measured solution, and different electromotive force will be generated due to the different acidity (hydroge...Read more -
Experimental detection of the effect of ABA on stomata closure
【principle】 Plant endogenous hormone ABA (abscisic acid) can close stomata and reduce leaf transpiration rate. Exogenous ABA also has the same effect. Weighing and microscopy can be used to directly or indirectly measure the stomata opening to test the role of exogenous ABA and deepen the under...Read more -
Determination of total root absorption area and active absorption area
【Principle】 According to the theory of plant mineral absorption, the initial absorption of solute by plants has the characteristics of adsorption, and it is assumed that a monolayer of adsorbed substances is uniformly covered on the root surface at this time, so it can be based on the amount of...Read more -
