Estrogen receptor assay
in polymorphous low-grade adenocarcinoma and adenoid cystic carcinoma of salivary gland origin.
This combination of in vitro techniques includes the GST-pulldown assay (CARLA test), which detects interactions between ER and a coactivator; a competition binding assay that assesses ligand interactions with the receptor; a yeast-based estrogen receptor assay
(YES); and a luciferase reporter assay in cultured MCF-7 cells that reveals transcriptional activation.
