Biological Activity

Description

FGF-8f Protein, Human is an isoform of FGF-8, an essential factor during embryonic development, involved in the progression of prostate cancer.

Background

Fibroblast Growth Factor 8 is an essential factor during embryonic development, overexpressed in several tumor types. Fibroblast Growth Factor 8 stimulates anti-apoptotic pathways and prevents tumor cell death[1].

Verified Bioactivity

The ED50 is <50 ng/mL as measured by 3T3 cells, corresponding to a specific activity of >2 × 104 units/mg.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS.

Endotoxin Level

<0.2 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.
