The present invention addresses the problem of providing a laminate that is easily manipulated and results in little damage to an original paraffin block sample when a paraffin section sample is prepared, a production method for the laminate, a preparation method for a paraffin section sample, and a preparation method for a paraffin sample piece.　Provided is a laminate that includes a substrate, a first paraffin layer that is provided on at least a portion of the surface of the substrate, and a second paraffin layer that is provided on at least a portion of the first paraffin layer, the melting point T1 of a first paraffin that constitutes the first paraffin layer being higher than the melting point T2 of a second paraffin that constitutes the second paraffin layer.

This invention relates to the field of paraffin sectioning technology and discloses a paraffin section pretreatment method suitable for plant spatial transcriptomics, comprising: (1) sample collection and fixation; (2) sample dehydration; (3) clearing; (4) paraffin embedding; (5) paraffin section preparation; and (6) pretreatment of sections before RNA FISH. This invention can be widely applied to various plant tissues, and its detection sensitivity can reach the visualization of low-expression genes (FPKM≤20), contributing to the popularization and development of plant spatial transcriptomics.
