get_protein_info: Retrieve Information on Antibodies Used for Protein Levels Determination

Description

Retrieve information on antibodies used by reverse-phase protein arrays (RPPA) to measure protein/phosphoprotein levels.

Usage

get_protein_info(csid = NULL, array_type = "protein_level", glist = NULL)

Arguments

csid

String corresponding to the Cancer Study Identifier

array_type

String, c("protein_level", "phosphorylation"). Retrieve information about antibodies used for detecting total protein levels or phosphorilated levels of the protein product of the gene of interest

glist

Character vector including one or more gene identifiers (ENTREZID or OFFICIAL_SYMBOL)

Value

Data Frame having one antibody per row and four columns
