應用
This product has been used to study differentiation of pancreatic acinar cell line (AR42J) into insulin-secreting cells and has been linked to a role in the growth and differentiation of islet cells in human pancreas.
生化／生理作用
Betacellulin, and the other members of the EGF family of growth factors, binds with high affinity to both EGFR and to erbB-4. Overexpression of Betacellulin with erbB-3 and erbB-4 has been linked to human endometrial adenocarcinoma.
注意
This product should be stored at -20°C. After preparation, the product can be stored at 2-8°C for one month, or frozen in aliquots at -20°C or -70°C for more extended storage.
準備報告
This product was lyophilized from a 0.2 μm filtered solution of PBS containing 5 mg of bovine serum albumin. It should be reconstituted by adding sterile PBS containing 0.1% HAS or BSA to a concentration greater than 1 μg/mL.
分析報告
The biological activity of this product is measured by an ability to stimulate H-thmidine incorporation in EGF-responsive mouse BALB/c 3T3 fibroblasts. The EC50 is defined as the effective concentration of growth factor that elicits a 50% increase in cell growth in a cell based bioassay.
