摘要:
Agglutinated and non-agglutinated sample material is separated by means of a separation material such as gel material or a bead matrix in a centrifugation step. Whether an agglutination reaction took place or not is determined by comparing the color intensities and/or the gray levels of images of the top side and the bottom side of the respective reaction vessel. Comparing the color intensities and/or the gray levels of the two images makes the automatic determination reliable and stable. Furthermore, the reaction wells are arranged in a two-dimensional array which provides a high throughput.
摘要:
The invention relates to a centrifuge for cleaning, washing or centrifuging a reaction vessel unit comprising a rotor (8) for holding at least one reaction vessel unit (2) with its opening(s) directed radially outwardly or radially inwardly, a motor for rotating the rotor (8) around a rotation axis (18), a housing (23). The centrifuge is characterized by a small gap between the rotor and the housing, or a cooling device for cooling an inner surface of the housing, or a loading mechanism comprising a flexible elongate beam (34) for extension and retraction of a reaction vessel unit (2).
摘要:
The invention relates to a microplate used in a method for determining the result of an agglutination reaction. Agglutinated and non-agglutinated sample material is separated by means of a separation material such as gel material or a bead matrix in a centrifugation step. Whether an agglutination reaction took place or not is determined by comparing the color intensities and/or the gray levels of images of the top side and the bottom side of the respective reaction vessel. Comparing the color intensities and/or the gray levels of 20 the two images makes the automatic determination reliable and stable. Furthermore, the reaction wells are arranged in a two-dimensional array which provides a high throughput.
摘要:
Method for carrying out a ligand binding assay in at least one reaction well, comprising the steps of filling the at least one reaction well with a sample liquid and overlaying the sample liquid with an oil film.
摘要:
The invention relates to a microplate comprising a plurality of wells arranged in a two-dimensional array, wherein each well is inclinable or pivotably mounted in the microplate so that the wells align with the direction of a centrifugal force during centrifuging of the microplate.
