Can telomeres make you immortal?

Telomerase is thus able to extend the life-span a cell, and has been dubbed the “immortality” enzyme. Recent evidence suggests telomeres also act as 'molecular sensors' of genomic damage and help limit the replication of cells with highly damaged DNA.

Consequently, how do you determine your biological age?

Companies that offer at-home testing measure biological age in saliva as an indicator of a person's overall biological age while most scientific studies use blood for this measure. Your biological age in your blood is often similar to that in your saliva because they have many of the same cell types. How does flow FISH work? Flow FISH is a telomere measurement technique that combines the use of fluorescent in situ hybridization (FISH) with flow cytometry. White blood cells (leukocytes) are isolated from a blood sample and mixed with fluorescent peptide nucleic acid (PNA) probes that bind specifically to the telomere repeats (TTAGGG).
