2 results about "Two dimensional electrophoresis" patented technology

Epitachophoresis (ETP) methods and devices that improve concentrating samples and / or separating components of samples. ETP methods and devices allow for electromigration in two dimensions. Electromigration of a sample may first occur in a first dimension along a single plane. Electromigration may then continue in a second dimension, which may be different from the first dimension. The volume where the electromigration occurs may significantly reduce from the first dimension to the second dimension. This smaller dimension may allow for increased concentration of samples or improved separation of components of a sample.

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.
