Résumé
The optimum convolution spectra of β-galactosidase and the linear equation of Qj=1.906×10-2＋4.946×10-3 C＋1.909×10-4 C2,r=1.0000 under the best condition were established by the convolution spectrum method.Based on the chromogenic substrate o-nitrophenyl-β-galactoside,a method for the determination ofβ-galactosidase activity in the COS-1 extraction sample which had been transfected transiently expression vector of β-galactosidase was determined by using the convolution curve transformation technology.The convolution spectrum method was compared with the absorption method and the result was satisfactory.The method was simple,convenient,fast and valuable to the biochemical analysis.
Résumé
Objective: To qualitatively identify 5 chlorin metal complexes which had similar structures. Methods: The compounds were identified by the convolution curve transformation technology and computer information process technology. Results: The results were demonstrated by match comparison and three dimensional differential diagram of convolution spectra. Five chlorin metal complexes were identified satisfactorily and 10 nonidentity identification results were acquired. Conclusion: The convolution spectrum method is simple and feasible for the identification of the compounds which have similar structures. [
