Provided is a highly sensitive in situ detection method for target molecules using mass spectrometry. The following steps: (1) A tissue or cell is brought into contact with the support surface, and molecules contained in the tissue or cell are transferred onto the support surface; (2) subjecting the support to mass spectrometry; and (3) detecting a target molecule present in a tissue or cell in situ , comprising detecting the target molecule based on the result of mass spectrometry. A method further comprising staining the target molecule by image processing in the step (3). [Selection figure] None |
