## Abstract __SELEX was used to create an RNA aptamer targeted to protein tyrosine phosphatase 1B (PTP1B), an enzyme implicated in type 2 diabetes, breast cancer and obesity. We found an aptamer that strongly inhibits PTP1B in vitro with a__ K__~i~ of less than 600 pM. This slowβbinding, highβaffin
