Telomer length determination

Service description

1-Determination of telomere length (TL) by Q-PCR using oral swabs: For this analysis we provide: an informed consent that contains personal data necessary for the TL analysis, and oral swabs, that we will send by commercial messenger to people interested in the analysis. The signed informed consent and the swabs will be returned to the IIB facility by the messenger service and we will extract the DNA and the analysis of TL by Q-PCR in triplicates. We will use as controls samples from the same age range of the patient or relative. We will provide the analysis of the results relative to the TL and to the percentile respect to the control population of similar age. 2- Determination of telomere length (TL) by southern blot using peripheral blood. For this analysis we provide: an informed consent that contains personal data necessary for the TL analysis that we will send by E-mal to the clinicians. Blood should be recovered in EDTA tubes, and the volume between 4 to 5 mls depending on the possibilities (age) and stage of the patient. The tubes with blood and the signed informed consent will be delivered to the IIB facility by messenger. We will proceed to extract the genomic DNA and to the analysis on medium TL by southern blot (by duplicates). We will provide the results as average telomere length obtained by a bio-informatic analysis of the southern blot and we will inform the results of the TL and to the percentile respect to the control population of similar age.
