Description

Synonym HOMG4,URG,EGF
Protein Construction A DNA sequence encoding the mature soluble form of human EGF (NP_001954.2) (Asn 971- Arg 1023) was fused with the Fc region of human IgG1 at the N-terminus.
Source Human
Expression Host Human Cells
Purity >90 % as determined by SDS-PAGE
Bio-activity Measured in a cell proliferation assay using Balb/C 3T3 mouse embryonic fibroblasts.
The ED50 for this effect is typically 0.1-0.6 ng/mL.
Endotoxin < 1.0 EU per 1μg of the protein as determined by the LAL method.
Stability Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N terminal Glu 20
Molecular Mass The recombinant human Fc/EGF chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 290 amino acids and has a calculated molecular mass of 33 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhFc/EGF monomer is approximately 37 kDa due to the glycosylation.
Formulation Lyophilized from sterile PBS , pH 7.4
  1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Storage Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted into smaller quantities for optimal storage and usage; Avoid repeated freeze-thaw cycles.
Reconstitution A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
MSTN / GDF8 Protein Description
Human epidermal growth factor (EGF), also known as urogastrone (URG) since it was isolated from urine based on its inhibitory effect on gastric secretion, is the founding member of the EGF-family of growth factors. All the members of this protein family have highly similar structural and functional characteristics. EGF is initially synthesized as a 130 kDa single-pass transmembrane protein containing 9 EGF-like units and 9 LDL-receptor class B repeats. The mature soluble EGF is a 6 kDa peptide corresponding to the EGF unit located proximal to the transmembrane domain. EGF is expressed in kidney, salivary gland, cerebrum and prostate, and plays an important role in the regulation of cell growth, proliferation, and differentiation by binding to its receptor EGFR. As a potent mitogen, EGF stimulates the growth of various epidermal and epithelial tissues both in vivo and in vitro. Furthermore, EGF is also identified as a magnesiotropic hormone that stimulates magnesium reabsorption in the renal distal convoluted tubule via engagement of EGFR and activation of the magnesium channel TRPM6. Defects in EGF are the cause of hypomagnesemia type 4 (HOMG4), a disorder characterized by massive renal hypomagnesemia and normal levels of serum calcium and calcium excretion.
