Abstract
The invention is directed to a process for extracting target cells from a three dimensional biological specimen by the steps imaging the three dimensional specimen; identifying target cells; registering the spatial parameters (x,y,z coordinates) of the target cells; and extraction of target cells according to their spatial parameters
Claims4
A process for extracting target cells directly from a three dimensional biological specimen by comprising the steps;
- a) imaging the three dimensional specimen using a light sheet microscope, the light sheet microscope including a detection lens;
- b) identifying target cells and determining spatial information (x,y,z coordinates of the target cells;
- c) storing the spatial information of the target cells;
- and
- d) extracting the target cells according to their stored spatial information,
- wherein the three dimensional specimen is provided with an optically inducible crosslinking reagent in at least one of the steps a), b), c) or d) and the optically inducible crosslinking reagent is crosslinked by activation by a one-photon crosslinking laser,
- wherein the detection lens of the light sheet microscope is used to direct the crosslinking laser onto the three dimensional specimen.
