Abstract
Kits and methods for single cell or multiple cell transcriptome analysis are provided. An adapter polynucleotide is disclosed which comprises a double-stranded DNA portion of 15 base pairs and no more than 100 base pairs with a 3′single stranded overhang of at least 3 bases and no more than 10 bases, wherein the double stranded DNA portion is at the 5′ end of the polynucleotide and wherein the sequence of the 3′single stranded overhang is selected from the group consisting of SEQ ID NOs: 1-8 and 9, wherein the 5′ end of the strand of the double-stranded DNA which is devoid of the 3′single stranded overhang comprises a free phosphate.
Claims4
A method of preparing a cell for transcriptome sequencing comprising:
- (a) incubating a plurality of RNA molecules derived from a single cell with a reverse transcriptase enzyme and a first oligonucleotide comprising a polydT sequence at its terminal 3′ end, a T7 RNA polymerase promoter sequence at its terminal 5′ end and a barcode sequence positioned between said polydT sequence and said RNA polymerase promoter sequence under conditions that allow synthesis of a single stranded DNA molecule from said RNA, wherein said barcode sequence comprises a cell barcode;
- (b) synthesizing a complementary sequence to said single stranded DNA molecule so as to generate a double stranded DNA molecule;
- (c) incubating said double stranded DNA molecule with a T7 RNA polymerase under conditions which allow synthesis of amplified RNA from said double stranded DNA molecule;
- and
- (d) fragmenting said amplified RNA into fragmented RNA molecules of about 200 nucleotides.
