One of the many important uses of PCR technology is that it can be used to label DNA probes with high specific activity. PCR technology has high specificity, and can synthesize probe DNA fragments in quantities within 1~2h if [α-32P]dNTP or other markers are added to the substrate
dNTPs, the probe DNA can be well labeled during DNA synthesis, and the incorporation rate of the marker can be as high as 70%~80%. Therefore, PCR labeling technology is particularly suitable for large-scale detection and non-radiolabeling. The disadvantage of this method is that a specific pair of PCR primers is synthesized.
Labeling can also be achieved by using small fragments prepared from probe DNA as primers.
Solution preparation
1. Prepare a stock solution
Unless otherwise stated, all unused stock solutions should be divided into disposable aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.
1.1* Acid Stock Solution (125X):
Add 20 μL DMSO to *ate (component B) to make a 125X* acid stock solution.
2. Prepare standard solutions
*Salt standard solution
Add 50 μL of 1 mM KH2PO4 (Component C) to 950 μL of deionized water or enzyme reaction buffer to give a 50 μM * saline standard solution (PS7). A 50 μM * saline standard solution (PS7) was taken and serially diluted 1:2 to obtain a serially diluted phosphate standard with deionized water or enzyme reaction buffer.
3. Prepare a working solution
Add 20 μL of 125X* stock solution to 2.5 mL of sterile H2O and mix well to make a working solution of *salt. Avoid potential Pi contamination. Note: Avoid direct exposure of *salts (component B) to light. Due to the high sensitivity of this assay to Pi, it is extremely important to use Pi-free labware and reagents.
