Abstract
Disclosed herein, inter alia, are devices and methods for transfer and analysis of tissue sections using carrier substrates.
Claims (22)
1. A method of detecting nucleic acids in a tissue section, comprising:
contacting a plurality of discrete tissue samples attached to a solid support with a plurality of circularizable probes, wherein a circularizable probe binds to a nucleic acid molecule in a discrete tissue sample, and wherein each discrete tissue sample comprises a tissue section comprising a width of about 4 mm to about 10 mm and a thickness of about 5 μm to about 12 μm;
forming a circular oligonucleotide in the tissue section, and amplifying the circular oligonucleotide to form amplification products; and
detecting the amplification products by binding a fluorescently labeled probe to the amplification product and detecting the fluorescent label.
2. The method of claim 1 , wherein the nucleic acid molecule is attached to a specific binding agent.
3. The method of claim 1 , wherein the nucleic acid molecule is an RNA molecule.
4. The method of claim 1 , wherein the nucleic acid molecule is a cDNA molecule.
5. The method of claim 1 , where the tissue section comprises liver tissue, kidney tissue, lung tissue, thymus tissue, adrenal tissue, skin tissue, bladder tissue, colon tissue, spleen tissue, or brain tissue.
6. The method of claim 1 , wherein the fluorescently labeled probe is a fluorescently labeled nucleotide.
7. The method of claim 1 , wherein the fluorescently labeled probe is a fluorescently labeled oligonucleotide.
8. The method of claim 1 , wherein each tissue section is a formalin-fixed and paraffin embedded (FFPE) tissue section.
9. The method of claim 1 , wherein each tissue section is a frozen tissue section.
10. The method of claim 1 , wherein a length and/or diameter of each tissue section is about 4 mm to about 10 mm.
11. The method of claim 1 , wherein a thickness of each tissue section is less than 6 μm, 7 μm, 8 μm, 9 μm or 10 μm.
12. The method of claim 1 , wherein each tissue section comprises breast tissue, lung tissue, colon tissue, lymph tissue, kidney tissue, bone tissue, tonsil tissue, or brain tissue.
13. The method of claim 1 , wherein the solid support is glass.
14. The method of claim 1 , wherein the nucleic acid molecule comprises a barcode sequence.
15. The method of claim 1 , wherein the circularizable probe comprises a barcode sequence.
16. The method of claim 1 , wherein the circularizable probe is a single stranded polynucleotide comprising a 5′-end and a 3′end, and forming the circular oligonucleotide comprises ligating the 5′-end and a 3′end together to form the circular oligonucleotide.
17. The method of claim 1 , wherein the circularizable probe is a single stranded polynucleotide comprising a 5′-end and a 3′end, and forming the circular oligonucleotide comprises extending the 3′end to form a complementary sequence of the nucleic acid molecule, and ligating the complementary sequence to the 5′-end to form the circular oligonucleotide.
18. The method of claim 1 , wherein each discrete tissue sample is separated from each other by about 1 mm or greater.
19. The method of claim 1 , wherein each discrete tissue sample is separated from each other by about 1 mm.
