The Human Protein Atlas is a website of protein expression in human tissues. It is an excellent resource of tissue and cell type protein localization. but only allows the query of a single protein at a time. We introduce HPAStainR as a new Shiny app and Bioconductor/R package used to query the scored staining patterns in the Human Protein Atlas with multiple proteins/genes of interest. https://tftoyes.shop/product-category/knight-rider/
