Determined by a mouse splenocyte survival assay. The expected ED50 for this effect is 0.5-2.0 µg/ml.
Properties
PURITY:
≥ 95% by SDS-PAGE gel and HPLC analyses.
PHYSICAL STATE:
Lyophilized
STORAGE CONDITIONS:
The recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background and References
BACKGROUND:
BAFF, a member of the TNF family of ligands, is expressed in T cells, macrophages, monocytes and dendritic cells. BAFF is involved in stimulation of B and T cell function, and is an important survival and maturation factor for peripheral B cells. BAFF signals through three different TNF receptors, TACI, BCMA and BAFF-R. The human BAFF gene codes for a 285 amino acid type II transmembrane protein containing a 46 amino acid cytoplasmic domain, a 21 amino acid transmembrane domain, and a 218 amino acid extracellular domain. Recombinant Human soluble BAFF is a 152 amino acid polypeptide (17.0 kDa), which contains the TNF-like portion of the extracellular domain of BAFF.
