After reconstituting the protein in water, it remains active and stable at 2-8°C for up to a week. However, for long-term stabilization at -20 to -80°C, further dilution with a buffer containing a carrier is necessary to prevent activity loss. It is recommended to use 5% trehalose or 0.1% BSA in water or PBS for extended storage. Working aliquots should have a minimum volume of 10 uL and a concentration above 1 ug/ml for optimal stability.

Gene Information
human ... EGF(1950)
General description
The gene EGF (epidermal growth factor) is mapped to human chromosome 4q25-27. The EGF gene encodes for a large type I membrane–anchored precursor protein which is cleaved into pro-EGF for generation of peptide hormone EGF. The mRNA is expressed in kidney, salivary gland, cerebrum and prostate. Recombinant human EGF is a 6.2kDa globular protein containing 53 amino acid residues including 3 intramolecular disulfide-bonds.
Application
EGF (epidermal growth factor) human has been used in the culture medium for the maintenance of MCF10A cells (human mammary epithelial cells).
Biochem/physiol Actions
EGF (epidermal growth factor) is a potent growth factor that stimulates the proliferation of various epidermal and epithelial cells. Additionally, EGF has been shown to inhibit gastric secretion, and to be involved in wound healing. EGF signals through a receptor known as c-erbB, which is a class I tyrosine kinase receptor. This receptor also binds with TGF (transforming growth factor)-α and VGF (vaccinia virus growth factor). Mutation in the EGF gene might be associated with risk of non- small cell lung adenocarcinoma. It is also involved in anaplastic thyroid cancer and renal hypomagnesemia. It controls cell differentiation and neurotrophic processes.
Physical form
Lyophilized with no additives.
Preparation Note
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C.

Is it necessary to dilute item no: SRP3027-500UG in a buffer with a stabilizer for extended storage as mentioned in the reconstitution portion of the specification. If so, would D-(+)-Trehalose dihydrate (cat#T0167) be appropriate? Also, specify the buffer considering that water is indicated as an appropriate diluent in the specifications.
