High density antibody arrays represent powerful technologies which have opened a new era in functional proteomics. However, when faced with a large magnitude of array data, you must apply comprehensive statistical and data mining analysis to discover potential biomarker panels and meaningful patterns. Biostatistical analysis can also help to evaluate the quality of protein expression data by detecting and extracting errors and confidence level. As one can get easily lost at this game, this post illustrates a selection of packages available, taking the example of High density antibody array services performed by tebu-bio laboratories in Europe, in collaboration with their partner RayBiotech. I doubt you will want to do it your self when you have realized what can be done for you, and at very affordable pricing!
