| 摘要 |
The invention relates to a laser microdissection system (100), comprising a microscope (10). The microscope comprises a reflected-light device (76), a microscope objective (41), and a laser unit (70). A beam path (b) of a laser beam of the laser unit (70) extends through the reflected-light device (76) and through the microscope objective (41) and intersects with an object plane (15) of the microscope objective (41) at an adjustable point of intersection. An electrophoresis unit (90) having an electrophoresis gel (91) is attached, or can be attached by means of coupling elements (35), below the object plane (15), wherein the electrophoresis gel (91) has at least one gel pocket (92) and the laser microdissection system (100) comprises positioning means (96) for positioning the electrophoresis gel (91) in parallel with the object plane (15) and in relation to a defined reference position, such that dissectates (99) of a sample (51) that can be arranged in the object plane (15), which dissectates are obtained by means of the laser beam of the laser unit (70), can be captured in the at least one gel pocket (92). The invention further relates to a corresponding electrophoresis unit (90) and an examination method. |
