  • Patent number: 5891639
    Abstract: Telomerase activity in a sample can be measured using a two reaction protocol. The first reaction involves the formation of telomerase substrate extension products from a telomerase substrate. The second reaction involves replication of the telomerase substrate extension products and/or amplification of signal generated by a bound probe. The presence of telomerase activity in a human somatic tissue or cell sample is positively correlated with the presence of cancer and can be used to diagnose a disease or other conditions of medical interest, as well as the course of disease progression or remission in a patient.

  • Patent number: 5834193
    Abstract: Methods and compositions for the measurement of telomere length have application in medical diagnostic, prognostic, and therapeutic procedures. The methods for measuring telomere length include primer extension-based methods and probe-based methods. The primer extension methods involve elongation of telomeric, linker, and/or subtelomeric based primers under conditions such that the telomere serves as a template for primer extension and that the resultant primer extension products can be compared to standards of known length to provide a measure of telomere length. The probe based methods allow for telomere length measurements using DNA from lysed or whole cells and involve hybridizing an excess of probe to all telomeric repeat sequences in the telomere, measuring the amount of bound probe, and correlating the amount of bound probe measured with telomere length.
