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.

文献和实验进行包装、逆转录和整合所需的顺式作用原件与编码反式作用蛋白的序列分离,分别构建在三个质粒表达系统上,即包装质粒、包膜质粒和载体质粒。包装质粒在巨细胞病毒(cytomegalovirus, CMV)启动子的作用下,控制除env以外所有病毒结构基因的表达;包膜质粒编码水泡口炎病毒(vesicular stomatitis virus,VSV)G糖蛋白;载体质粒中含有目的基因。用这三种质粒共转染包装细胞如人胚胎肾293T细胞,在细胞上清中即可收获只有一次感染能力、而无复制能力的慢病毒颗粒。第一代慢病毒
顺式作用序列,与包装成分互补,同时具有异源启动子控制下的多克隆位点及在此位点插入的目的基因。为了进一步降低两部分同源重组产生有复制能力病毒的可能性,在这种二质粒表达系统的基础上,Naldini[3 ]和Kaf ri[4 ]等人构建了三质粒表达系统,即整个LV 系统由包装质粒、包膜质粒和载体质粒三种质粒组成。用水疱性口炎病毒G 蛋白( vesicular stomatitis virus ,VSV2G) 代替 HIV 本身的包 膜蛋白 ,扩大了载体的感染谱[5 ] ,增加了LV 的稳定
