Biochemical composition of suction blister fluid determined by high resolution multicomponent analysis (capillary gas chromatography--mass spectrometry and two-dimensional electrophoresis).


The biochemical composition of blister fluid was compared with serum and with blister fluid from erythematous lesions induced by ultraviolet irradiation. By using glass capillary gas chromatography--mass spectrometry over 100 metabolites were determined and with the aid of two-dimensional high resolution electrophoresis (the ISO-DALT system) several hundred protein spots were seen. The results show that the suction blister fluid qualitatively have a serum-like pattern but that the concentration of each compound was smaller than in serum. Also in suction blisters raised on erythematous reactions induced by ultraviolet light the same pattern was seen. The content of sodium, potassium and chloride was the same in suction blisters raised on erythematous and normal skin as that of serum.
