Highly purified nuclear protein is required when using an electrophoretic mobility shift assay (EMSA) to study transcription factors, e.g. nuclear factor-κB (NF-κB), a major transcription factor that regulates both innate and adaptive immune responses following infection. Although many protocols have

Fibroblast growth factor 1 (FGF1) is an autocrine/paracrine regulator whose binding to heparan sulphate proteoglycans effectively precludes its circulation. Although FGF1 is known as a mitogenic factor, FGF1 knockout mice develop insulin resistance when stressed by a high-fat diet, suggesting a
