Biological Activity

Description

Probetacellulin Protein, Mouse, induces differentiation of pancreatic β-cells and promotes regeneration of β-cells in experimental diabetes.

Background

Betacellulin (BTC), a member of the epidermal growth factor (EGF) family, induces differentiation of pancreatic β-cells and promotes regeneration of β-cells in experimental diabetes. BTC stimulates DNA synthesis in fibroblasts and vascular smooth muscle cells. BTC plays a role in regulating growth and/or differentiation of endocrine precursor cells of the fetal pancreas. BTC is found to convert amylase-secreting pancreatic AR42J cells into insulin-producing cells and to have a mitogenic effect in human undifferentiated pancreatic epithelial cells[1].

Verified Bioactivity

Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50 this effect is ≤0.9548 ng/mL, corresponding to a specific activity is ≥1.047×106 units/mg.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, 200 mM arginine, pH 8.0 or PBS, pH 7.4.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.
