Substraction library:
A cDNA library that only contains cDNAs uniquely expressed in a given cell or tissue. e.g T cells and B cells will express many common RNAs, as well as a very small percentage which will be unique for T cells and B cells respectively. To make a T cell subtraction library, the cDNA from a T cell library is hybridized with a vast excess of B cell RNA. The commonly expressed genes will result in RNA-cDNA hybrids which can be removed (or subtracted) to leave only T cell specific cDNAs
