Apparatus, systems and methods for microinjection of samples into amphibian oocytes

摘要

The invention provides an apparatus for the microinjection of samples into amphibian oocytes, comprising a tray (9) for holding a plurality of amphibian oocytes (13), an injection needle (6) for injecting a sample into the amphibian oocytes (13), driving means (4, 11, 12) for moving the relative position between the tray (9) and the injection needle (6) and controlling means (1, 2) for controlling the movement by setting the depth of the injection needle (6) relative to the tray (9) or the amphibian oocytes (13) in the sample injection and for injecting the sample into the amphibian oocytes (13) at that depth. According to the present invention, the sample can be injected into amphibian oocytes (13) with constant depth precisely, and the quality of oocytes or the positional site of needle injection can be recorded as product information. <IMAGE>
