1. Translate a paragraph: Gene gun experiment process (1)
All parameters should be calibrated settledprior, such as pressure, appropriate target spacer, and sample volume material for optimallloading GDS-80 low-pressure gene delivery system 99.999% nitrogen or helium gas cylinder, secure chain safety issues, target spacing of 3 cm and 6 cm, 3mm filter paper, Coomassie Brilliant Blue (CBB) staining solution (0.1% Coomassie Brilliant Blue R-250 dissolved ratio of distilled water/methanol/acetic acid=45/45/10). The program requires selecting the correct bucket and assembling the whole system according to the instructions. Perform leakage test GDS-80 manually as shown. Check the pressure regulating handle by loosening it counterclockwise first. Also, ensure that the needle valve is open and the flow meter is closed by turning it counterclockwise. Open the gas cylinder valve and adjust the pressure control handle to indicate the desired pressure on the secondary pressure gauge. Loosen the differential needle valve completely and tighten it again to the valve with recommended settings (as shown in Table 1). If the pressure setting is not recommended (Table 1), please find the pressure setting area and gradually increase the thrust needle valve by adjusting the difference. For example, if the required pressure is 36 times, adjust the differential needle valve from 5 to a maximum of 6 turns. Pull the trigger several times to check if the pressure remains fixed. Typing is too tiring, please accept it or~~~~~~~~~~~~~~~~~~~!!!!!!!!!!
