Fig. 2. Tissue specificity of ion channel gene expression. (A) PCA of ion channel gene expression. Each dot represents one sample. PC1 stands the first principal component while PC2 is the second principal component. (B) Cumulative distribution of the mean TPM for different organ/tissue types. (C) Histogram of the TSI of the ion channel genes and the other genes. PCA, principal component analysis; TPM, transcripts per million; TSI, tissue specificity index.
