gel retardation assay

Electrophoretic mobility shift assay (EMSA, also called gel retardation assay or gel shift assay) is an in vitro method to detect the interaction between proteins and nucleotides. It is originally used to detect transcription factors, and is now further developed into investigating DNA-protein interactions, RNA-protein interactions, and even DNA-RNA interactions. Profacgen provides professional EMSA service to identify potential DNA or RNA binding proteins with high efficiency and accuracy.
