preparation example Construction

[0036] The preparation process of BUIPTP among the present invention is as follows:

[0037] (1) Add 0.12mol·L to a 250mL round bottom flask -1 100mL of hydrochloric acid, 60mmol of pyrrole and 5mmol of the corresponding aromatic aldehyde were added, and the reaction was carried out at room temperature and protected from light under magnetic stirring. The reaction system was monitored in real time by TLC. Control the appropriate reaction time, when TLC monitors that the reaction substrate aromatic aldehyde is almost completely consumed, the reaction is ended, the reaction solution is neutralized to pH=8-9 with ammonia water, filtered, and continuously washed with petroleum ether until the filtrate is colorless. Send a little of the same body obtained by suction filtration to HPLC to monitor the content of each component. The rest of the solid can be recrystallized with ethyl acetate-petroleum ether to obtain pure dipyrromethane, and then dried under reduced pressure to obtain ...

Abstract

The invention discloses application of a BUIPTP (binuclear uranyl-isophthalaldehyde-tetrapyrrole) to ATP (Adenosine Triphosphate) analysis and belongs to the technical field of biochemical analysis detection method. The application comprises the following steps: determining optimal conditions for detecting ATP; preparing a BUIPTP detection base solution; drawing a standard curve of determined ATP;analyzing the content of the ATP in a sample: weighing a sample to be detected, which contains the ATP; adding water for dissolving or diluting; adding a Tris-HCl buffering solution; while stirring,dropwise adding the BUIPTP detection base solution into the solution; determining second-grade scattering spectral intensity at a part with optimal wavelength. By adopting a detection method providedby the invention, the deviation between the detected ATP concentration and objective concentration is less than 2.5 percent; the detection method provided by the invention has very high accuracy; whenthe concentration of the ATP is lower than 0.75nmol.L<-1>, the ATP still can be detected; the detection method has a good detection effect in a range of 2.5 to 500nmol.L<-1>.

Description

technical field [0001] The invention relates to the technical field of biochemical analysis and detection methods, in particular to the application of a dinuclear uranyl complex in ATP analysis. Background technique [0002] Adenosine triphosphate (ATP) is a high-energy compound, which is the direct source of energy required for all life activities of tissue cells in organisms. It can store and transfer chemical energy and participate in the metabolism of proteins, fats, sugars and nucleic acids in the body. ATP plays an important role in various physiological and pathological processes of cells, and can be used as an important marker of cell activity. ATP is also often used as an indicator to detect microbial contamination. [0003] The existing ATP detection methods generally have the disadvantages of cumbersome operation, long time-consuming, complicated preparation process, high requirements for instruments and equipment, and low precision. Therefore, it is of great si...
