If you suspect that your target is rare and likely to be poorly expressed compared with more abundant messages, consider using our subtraction services. Proprietary, self-subtraction, or tissue-tissue subtraction techniques reduce abundant sequences 10 to 100 fold, making it easier to find rare or low-expressed targets. The resulting normalized library enhances discovery of novel sequences and needs less sequencing—especially important for high-throughput applications.
