Two-Dimensional Electrophoresis. Two-dimensional electrophoresis is a powerful technique that combines both of these forms of protein analysis providing a broad survey or snapshot of proteins in specific cells or tissues, either in a developmental or in a physiological stage.
A strip detection method, device, medium and product
The application discloses a strip detection method, device, medium and product, relates to the strip detection field, and the method comprises the following steps: carrying out data preprocessing on a two-dimensional electrophoresis image; the data preprocessing comprises the following steps: background removal, background removal and normalization; one-dimensional intensity projection is carried out on the preprocessed image, and one-dimensional intensity curve is generated; the one-dimensional intensity curve is used for representing the overall intensity distribution of each row of pixels in the preprocessed image; the one-dimensional intensity curve is detected peak value, and the search interval of the strip is determined; in the search interval corresponding to each strip, the center curve, the upper boundary curve and the lower boundary curve of the strip are determined by adopting a column-by-column scanning algorithm; and the strip is positioned according to the center curve, the upper boundary curve and the lower boundary curve of the strip. The application can improve the efficiency, accuracy, adaptability and operation convenience of strip detection in electrophoresis experiments.
