Abstract
The present disclosure provides methods of preparing a biological specimen for imaging analysis, comprising fixing and clearing the biological specimen and subsequently analyzing the cleared biological specimen using microscopy. Also included are methods of quantifying cells, for example, active populations of cells in response to a stimulant. The present disclosure also provides devices for practicing the described methods. A flow-assisted clearing device provides rapid clearing of hydrogel-embedded biological specimens without the need of specialized equipment such as electrophoresis or perfusion devices.
Claims22
A method comprising:
- (a) providing a whole, fixed tissue sample in a non-electrophoretic device;
- and
- (b) flowing a clearing buffer through the non-electrophoretic device for at least 8 days, thereby clearing the whole, fixed tissue sample to generate a cleared tissue sample, wherein the flowing is performed without electrophoresis.
