Variation of protein profiles with body site.

<p>Differences in epidermal protein profiles among anatomic sites in four normal subjects (Ctls 1–4). Shown are 4 proteins distinguishing the profile of (<b>A</b>) palm and (<b>B</b>) (fore)head from the other sites. (<b>C</b>) Comparisons of relative levels of KRTs 6, 9, 10 and 16 in arm (A), forehead (H) and palm (P) by immunoblotting in samples obtained with tape circles from a normal subject.
