(A) Micro well plate arrays of SS and normal tear samples. Representative examples of open and closed eye tear samples from the same SS or normal patients are shown. Location of cytokine capture antibody spotted onto the array is indicated in the array matrix. Raw images of cytokine expression levels are shown. (B) Unsupervised hierarchical clustering of normalized protein levels from closed eyes. Plot of the first principle component of normalized protein levels. The first eigenvector was multiplied by the data matrix to generate a score value for each sample. Green points are controls, red points are cases. Black points are mean values and black lines represent 95% SE regions for each group.
