Abstract: A method for obtaining a single-cell mRNA sequence, including: (1) capturing mRNA of a cell by using a cell tag carrier, and performing reverse transcription to obtain cDNA having a cell tag; (2) obtaining multiple cDNA fragments having molecular tags by using a transposase complex and a molecular tag carrier; (3) performing high-throughput sequencing; (4) performing sequence assembly according to the molecular tags to obtain the sequence of each mRNA; and (5) obtaining the sequence of all mRNAs of each single cell according to the cell tags.

Abstract: A method for constructing a sequencing library, a sequencing library and a sequencing method.

Abstract: Disclosed is a method for obtaining a single-cell mRNA sequence. The method of the present invention comprises: (1) capturing mRNA of a cell by using a cell tag carrier, and performing reverse transcription to obtain cDNA having a cell tag, cDNAs from the same cell having the same cell tag, and cDNAs from different cells having different cell tags; (2) obtaining multiple cDNA fragments having molecular tags by using a transposase complex and a molecular tag carrier, the fragments from the same cDNA having the same molecular tag, and the fragments from different cDNAs having different molecular tags; (3) performing high-throughput sequencing; (4) performing sequence assembly according to the molecular tags to obtain the sequence of each mRNA; and obtaining the sequence of all mRNAs of each single cell according to the cell tags. The method provided by the present invention can be used for obtaining the sequence of all mRNAs of each of a large number of single cells by means of high throughput.
