Biological Activity

Description

Probetacellulin Protein, Human is a glycoprotein, improves glucose tolerance by promoting β-cell differentiation and regeneration from ductal and/or acinar cells.

Background

Betacellulin (BTC), a member of the epidermal growth factor family, is expressed predominantly in the human pancreas and induces the differentiation of a pancreatic acinar cell line (AR42J) into insulin-secreting cells. Betacellulin binds and activates the EGF receptor (EGFR/erbB-1) and erbB-4, and it induces tyrosine phosphorylation of erbB-2, which couples with the EGFR or erbB-4[1].

Verified Bioactivity

The ED50 is <0.01 ng/mL as measured by murine Balb/3T3 cells, corresponding to a specific activity of >1.0 × 108 units/mg.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS.

Endotoxin Level

< 0.2 EU/μg of protein by gel clotting 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.
