Quantitative method for E. coli cell sonication disruption based on firefly luciferase
ActiveCN116465877Breduce dosageHigh detection sensitivityMicrobiological testing/measurementChemiluminescene/bioluminescenceProtein targetLivestock breeding
This invention relates to a quantitative method for ultrasonic disruption of *E. coli* cells, specifically a method based on firefly luciferase in *E. coli* cells. The method involves mixing *E. coli* expressing firefly luciferase as an internal standard with a suspension of target protein-expressing bacteria, followed by ultrasonic disruption of the cells. The degree of disruption of the target protein-expressing bacterial suspension is quantitatively calculated by measuring the activity of the firefly luciferase. The target protein-expressing bacterial suspension uses *E. coli* expressing the target protein. Compared with existing technologies, this invention overcomes the shortcomings of complex experiments, low efficiency, and unstable accuracy in existing technologies. It achieves efficient and highly accurate quantification of the degree of ultrasonic disruption of *E. coli* cells, reduces experimental complexity, and improves research and development efficiency and accuracy. This provides a scientific basis and new approach for the development of new feed protein resources and livestock breeding research, and has broad application potential.

Part dimensional inspection methods, devices and computer equipment
PendingCN122312518AHigh precisionImprove positioning efficiencyPattern recognitionComputer graphics (images)
This application relates to a method, apparatus, and computer device for detecting the dimensions of parts. The method involves acquiring target images containing multiple parts of different categories from an image acquisition system; inputting the target images into a target detection model for target detection to obtain the bounding box information and category information of each part; for each part, determining the sub-pixel coordinates corresponding to the bounding box information of the part based on the target image and the bounding box information; and determining the size information of the part based on a preset candidate mapping relationship between pixel coordinates and size information, as well as the sub-pixel coordinates corresponding to the category information and bounding box information of the part. The target detection model identifies the bounding box information and category information of all parts in the image at once, eliminating the need to set separate matching templates for different parts and improving localization efficiency.
