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.

文献和实验亦称共尾幼虫、多头囊尾蚴、共囊尾蚴。系多节绦虫类之囊尾蚴的一型,常以哺乳类为中间寄主。在1个大的尾囊壁上长着多个翻转的头节,即多个头节共有一个大的尾囊。寄生于狗体的多头绦虫(Multiceps millcepes)的多头蚴(亦称大脑多头绦虫Coenurus cerebralis)曾发现于羊脑中,是脑共尾幼虫,大小为蚕豆至鸡蛋这一范围,成为羊的眩晕症的原因。
多节绦虫类囊虫的一种类型。是从卵壳脱出的六钩蚴( oncosphere)进入中间宿主体内后而形成的。身体有从豌豆粒至鸡蛋那样大,甚至有时达到小儿头那样大。在包囊中其头节(头圆锥)呈内翻状态,与中间宿主一起被纳入终局宿主体内,在终局宿主体的消化管内,宿主的体液浸入包囊,而内翻的头节就向外翻转而突出,附着于消化管壁上,舍弃包囊,由与头节相连的颈部不断形成新的节片而形成绦虫的成体。囊尾蚴是囊虫中最原始的类型,它的变态有多头蚴( coenurus)和棘球蚴( echinocoecus)。
,常见有以下类型(图15-3)。 图15-3 绦虫的幼虫 囊尾蚴俗称囊虫(bladder worm),是半透明的小囊,其中充满囊液,囊壁上有一个向内翻转的头节。另一种囊尾蚴型幼虫,囊内有多个头节,称多头蚴(coenurus)。 棘球蚴(hydatid cyst)是一种较大的囊,囊内无数头节称原头蚴或原头节(protoscolex);此外,还有许多小的生发囊(brood capsule),生发囊附于囊壁或悬浮在囊液中,其内又可有许多头节或更
