FGF-8 is a heparin binding protein of the FGF family which works to control cell division, differentiation, and function. These proteins are especially prominent during prenatal development and postnatal growth. FGF-8 can be spliced in four different ways. The products of the FGF-8 splicing events are as follows: FGF8A, 8B, 8E and 8F. This recombinant product represents isoform 8B.
<1.0 EU/μg of recombinant protein as determined by the LAL method.
Biological Activity Comment
The bioactivity was determined in a NIH/3T3 cell proliferation assay. The ED50 was in the range of 0.05 - 0.5 ng/ml.
Weight
22.5 kDa
Description
A quick spin of the vial followed by reconstitution at 100 μg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.
Format
Lyophilized PowderLyophilized from a 0.2 μm filtered solution in 20mM phosphate buffer, 0.2 mM EDTA and 1M NaCl (pH 8.0)
Purity
>95% as determined by SDS-PAGE
Storage
The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
