The present disclosure generally relates to devices and methods for effecting epitachophoresis. Epitachophoresis may be used to effect sample analysis, such as by selective separation, detection, extraction, and/or pre-concentration of target analytes such as, for example, DNA, RNA, and/or other biological molecules. Said target analytes may be collected following epitachophoresis and used for desired downstream applications and further analysis.

Provided herein are methods of identifying a methylation status of an analyte in a biological sample. Also provided herein are methods that combine identifying the methylation status with spatial technology to identify the location of a methylation status in a biological sample.

The present invention relates to the field of nucleic acid capture. The present invention inter alia concerns methods of producing a surface on which multiple copies of each of multiple DNA oligonucleotide species are covalently attached. Particles on the surface of which multiple copies of each of multiple DNA oligonucleotide species are covalently attached are also disclosed. Further, the present invention provides methods for enriching or depleting one or more species of nucleic acid molecules in/from a sample, including in/from partially isolated nucleic acids, isolated nucleic acids, biological samples, crude tissue lysates, cleared tissue lysates, crude cell lysates, cleared cell lysates, and processed and amplified nucleic acid sequencing libraries.

Embodiments relate to the preparation of nucleic acid libraries. Some embodiments relate to the preparation of normalized nucleic acid libraries, such as libraries in which the amounts of amplified nucleic acids are substantially the same for different amounts of input nucleic acids. Some embodiments relate to preparation of indexed nucleic acid libraries with certain adaptors.

Some embodiments described herein relate to a substrate with a surface comprising a silane or a silane derivative covalently attached to optionally substituted cycloalkene or optionally substituted heterocycloalkene for direct conjugation with a functionalized molecule of interest, such as a polymer, a hydrogel, an amino acid, a nucleoside, a nucleotide, a peptide, a polynucleotide, or a protein. In some embodiments, the silane or silane derivative contains optionally substituted norbornene or norbornene derivatives. Method for preparing a functionalized surface and the use in DNA sequencing and other diagnostic applications are also disclosed.
