FIG. 2.

Multiplexed protein detection from human skin using the ELIPatch. (a) Seven cytokines are measured from three sites of a healthy volunteer. Error bars: standard deviation. Line: limit of detection. (b) Antimicrobial protein is measured from various sites of a healthy volunteer using the ELIPatch. (c) Seven cytokines are measured from the inner forearm region of three healthy volunteers. Line: limit of detection. N.D. means non-detectable. (d) The measured values of three cytokines with the increasing stimulus and the number of tape stripping repetitions of skin. (NTC: no target control). (e) Spatial distribution of single cytokine on the inner forearm with multiple stimulus points [red boxes in (b)]. (i) IL-1α levels measured. (ii) IL-17A levels measured. All values are given in arbitrary units (A.U.).
