StemBeads^® EGF is the newest member of the StemBeads^® family and offers you the same reliability and flexibility as our other StemBead products. EGF is a growth factor that stimulates proliferation of many cell types including stem cells. Just like most growth factors, however, at temperatures used to grow cells EGF can become unstable leading to cell signaling deficits and non-optimal cellular performance. Our StemBeads^® EGF releases a constant level of EGF allowing for a consistent delivery of EGF to your cell cultures for optimal performance.
