Stability and Storage
Shipped at 4°C. Store at -20°C. Store under Desiccating conditions.
pH: 7.40 Constituent: PBS
This product is an active protein and may elicit a biological response in vivo, handle with caution.
ReconstitutionCentrifuge the vial prior to opening. Reconstitute in sterile distilled H2O to a concentration of 100 µg/ml. This solution can then be diluted into other aqueous buffers. Reconstituted ab123846 should be
stored at 4°C for 2-7 days and at -20°C for future use. For long term storage it is recommended to add a carrier protein (0.1 % HSA or BSA) and store as working aliquots at -20°C.
FunctionPotent mitogen for retinal pigment epithelial cells and vascular smooth muscle cells. The effects of betacellulin are probably mediated by the EGF receptor and other related receptors.
Tissue specificitySynthesized in several tissues and tumor cells. Predominantly expressed in pancreas and small intestine.
Sequence similaritiesContains 1 EGF-like domain.
Cellular localizationCell membrane and Secreted > extracellular space.
