Lipids were extracted from a 1cm portion of PTFE implants inserted into the upper arm of healthy volunteers and removed on days 3, 5, 7 and 14. A 100 mm skin punch biopsy was used as the baseline (day 0). Lipids were extracted from those samples and subjected to targeted analysis via LC tandem mass spectrometry. The data shown is the average lipid content from 7 volunteers (n=7) normalized to total sphingolipids ± SD. The lipid content is depicted in pmol specific lipid/pmol total sphingolipids found in 1cm of PTFE insert.
