Biological Activity
The activity is determined by the dose-dependant stimulation of IL-8 production by human PBMC. The ED50 for this effect is less than 10ng/ml corresponding to a Specific Activity of 100,000IU/mg. Please note: results may vary with PBMC donors.

Description
BLyS Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 153 amino acids and having a molecular mass of 17007 Dalton.
The BAFF is purified by proprietary chromatographic techniques.

Formulation
Each mg contains 1.6mg mannitol and 1.2mg HSA.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized BLyS in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
