Cucumber, young melon, leaf surface, fattening, anti-buckle
The occurrence of bent cucumber in cucumber is caused by the imbalance of nutrient and hormone supply in juveniles, which hinders the development of young melons. If the female flower of cucumber has just withered, and the young melon has just appeared, spray 1500 times 0.001% natural brassinolide and 0.2% urea mixture on the leaf surface, and spray 0.2% potassium dihydrogen phosphate on the leaf surface after 5-7 days. , 800 times humic acid active liquid fertilizer mixture. Evenly spray all the stems, leaves and young melons to start dripping with water drops. Promoting the development of young melons can prevent the cucumber from bending.

PCR ( Polymerase Chain Reaction)
It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
Superyears General 2215 RT-qPCRadopts all-in-one with an industrial art design, combining the Analytical Instrument, Large touch screen, and Computer. General 2215 RT-qPCR is equipped with the proven thermal-cooled electric technology, which can recognize the speed rate of temperature control faster and obtain high-quality testing results within 40 minutes. To ensure the sensitivity and stability of the testing a design with traditional beam path with a susceptible CMOS image sensor is used. In addition, General 2215 supports multiple PCR analysis and High-resolution Melt Curve (HRM) analysis, compatible with the mainstream reagent kit in the market. It will be the best assistant and your preferred RT-qPCR.
