CRISPR/Cas12a-based helicase-dependent isothermal amplification detection technology and application

Номер: CN116536453A
Принадлежит:

The invention belongs to the technical field of biological detection, discloses a helicase-dependent isothermal amplification detection technology based on CRISPR/Cas12a and application, and particularly discloses a reagent for detecting a monkey pox virus B6R gene, the reagent comprises crRNA for detecting the B6R gene and/or a primer pair for amplifying the B6R gene; the crRNA comprises an anchoring sequence and a guide sequence, the anchoring sequence can be combined with the Cas protein, and the guide sequence is matched with an amplification product sequence of the primer pair. According to the reagent for detecting the carbon monkey pox virus B6R gene, provided by the invention, the primer pair in the reagent can be used for an HDA isothermal amplification technology so as to rapidly and accurately detect the carbon monkey pox virus B6R gene, and the reagent is high in sensitivity and relatively strong in specificity.

Black-rice crust

Номер: CN0001107003A
Автор: ZIBIN TANG, TANG ZIBIN
Принадлежит:

The present invention uses black rice as main raw material and concerts black soybean, black sesame, maize flour, natural pollen, and gynostemma saponin, the product of bulking black rice crust is obtained through deep-frying process. Since the natural plant foods containing wholly and abundant nutritive components are selected, the scientific preparation makes the plant fat and necessary vitamins be intensified reasonably, and the nutritive components keep in saturated state of high energy. Through reasonable bulking the stinking smell of the product has been removed and the product is sterilized by deep frying. It is crisp and palatable.

Kit and detection method for detecting gene mutation sites through fluorescent quantitative PCR based on lock ring probe

Номер: CN115927573A
Принадлежит:

The invention discloses a fluorescent quantitative PCR (Polymerase Chain Reaction) kit for detecting a gene mutation site based on a lock ring probe and a detection method. According to the invention, a locked loop probe connection technology in an RCA technology is combined with a real-time fluorescent quantitative PCR technology, point mutation is detected by using a locked loop probe connection characteristic, signal amplification is realized by using a qPCR technology, the sensitivity is high, and the specificity is good; the T478K mutation site of the SARS-cov2-Delta mutant strain, the CD17 mutation site of the thalassemia and the 531 mutation site of the rpoB gene of the mycobacterium tuberculosis rifampicin drug-resistant strain are detected; wherein the lowest detection limit of the SARS-cov2 can reach 54.9 fM, and the detection limits of the thalassemia and the tuberculosis drug resistance are 95.35 zM and 55.12 aM respectively. The method can also be widely applied to detection ...
