Method for generating a subtracted cDNA library and uses of the generated library
First Claim
1. A method of generating a subtracted cDNA library of a population of cells comprising:
- a) generating a λ
ZAP cDNA library of the cells;
b) converting the λ
ZAP cDNA library into a phagemid cDNA library;
c) preparing double-stranded phagemid DNAs;
d) isolating double-stranded DNAs from the prepared phagemid DNAs;
e) releasing the double-stranded cDNA inserts from the double-stranded DNAs by digestion of the nucleic acids with appropriate restriction enzyme;
f) denaturing the isolated double-stranded cDNA inserts;
g) hybridizing the denatured double-stranded cDNA inserts with labelled single stranded nucleic acid molecules, which are to be subtracted from the cDNA library; and
h) separating the hybridized labelled single-stranded nucleic acid molecules from the double stranded cDNA inserts, thereby generating a subtracted cDNA library of a population of cells.
