Existence of life-time stable proteins in mature rats—Dating of proteins’ age by repeated short-term exposure to labeled amino acids throughout age
Fig 8
Tracer enrichment in patellar tendon connective tissue proteins, CT.
(A) Fet-Pro, (B) Pup-Phe, (C) Wea-Leu, (D) Pub-Pro, (E) Adu-Gly. Male (triangle) and female rat (circle) and values are represented as individual enrichment values (%) in the patellar tendon CT. The dashed vertical line indicates the start of the injection period of the tracer. An exponential decay regression curve is marked by a grey line in A-C (t1/2: (A) 14.0 days, (B) 9.6 days, (C) 14.2 days).
