After adding a certain amount of protein coating solution to the polyethylene carrier, most of them are placed in a refrigerator at 4 ℃ overnight to allow the solid surface to fully adsorb, or incubate at 37 ℃ for 2h to achieve the same adsorption effect, but the 37 ℃ coating 2 3h and 1h, the difference between the last measured absorbance values ​​is not significant. The kinetic study of protein adsorption on polystyrene enzyme plate shows that: 1MIN after adding the coating solution, adsorption will occur on the solid phase, the amount of adsorption is related to protein concentration and coating time. When the protein concentration is 5ug / mL, the coating 60MIN has obvious adsorption. After 12h, the adsorption amount no longer increases with time: when the protein concentration is 10ug / mL and 20ug / mL, the adsorption of the two is similar, the coating is 3min There will be obvious adsorption, the adsorption is complete after 6h, the adsorption capacity in 5min is 30% of 6min
For the working population, sedentary is a common normal, all kinds of lumbar disease, cervical spondylosis "into" people's body, bring a lot of trouble to people. Sitting for more than 2 hours without standing up and changing sitting posture is considered as sedentary.
Stand up desk is of great help to healthy office, and modern people's demand for health is also growing. Fully stand in the perspective of users to think about the problem, and the lifting desk with freely adjustable height can bring users a new experience of healthy office.
stand up desk can adjust the height of the desk according to its own needs, so that it can work in the most comfortable state.
