Abstract: The present application relates to transcriptome sequencing and biomolecule space information detection. Specifically, the present application relates to a method for positioning and labeling a nucleic acid molecule, a method for constructing a nucleic acid molecule library for transcriptome sequencing, and a kit for implementing the method.

Abstract: A DNA library sequence for increasing the number of chip probes and an application thereof. The DNA library sequence comprises two or more position information labeling sequences and three or more fixed sequences, wherein the position information labeling sequences and the fixed sequences are arranged at intervals. The DNA library sequence increases the number of probes of a chip used for spatiotemporal omics, and then a capture number of transcript genes is increased. The present invention has a very high application prospect.

Abstract: The present invention provides a sequencing method based on a single fluorescent dye, in which a self-luminescence signal is used to distinguish the sequential incorporation of different nucleotides, thereby realizing the determination of the polynucleotide sequence.

Abstract: The present invention provides a method for sequencing polynucleotides. Sequential incorporation of different nucleotides is detected by using the same light emitting signal, thereby achieving the determination of polynucleotide sequences.
