How many samples and cancer types are represented on the array?
There are 432 samples from 11 types of tissue. Each tissue is represented by 40 samples; 25 samples are from cancer tissues and 15 are from normal tissues. Some tissues have fewer samples due to limited availability (Prostate 13 normal; Melanoma 22 cancer and 14 normal; Liver 23 cancer). There are four different protein concentrations for each sample and these are spotted in triplicate.
