• Predicted molecular weight: 20.6 kDa
• No endotoxins, TAGS, and carrier-free
• Naturally folded and post-translationally modified

IBI recombinant proteins are expressed inPichia pastoris(yeast) system which provides many advantages overE. colisystems. Yeast systems promote proper protein folding and post-translational modifications for greater bio-activity. The recombinant proteins are endotoxin free and are purified without HIS-TAGS or any other TAG. IBI’s yeast expression system has proven to produce more active proteins that more closely resemble their host form.

BAFF (B-cell Activation Factor), also known as Tumor Necrosis Factor Superfamily member 13B (TNFSF13B) is a member of the tumor necrosis factor ligand (TNF) ligand family. Nineteen cytokines have been identified as part of the TNF family on the basis of sequence, functional, and structural similarities. Family members include TNF beta (TNFSF1), TNF alpha (TNFSF2), Lymphotoxin beta (TNFSF3), OX40 Ligand (TNFSF4), CD40 Ligand (TNFSF5), Fas Ligand (TNFSF6), CD27 Ligand (TNFSF7), CD30 Ligand (TNFSF8), 4-1BB Ligand (TNFSF9), TRAIL (TNFSF10), TRANCE/RANKL (TNFSF11), TWEAK (TNFSF12), APRIL(TNFSF13), BAFF (TNFSF13B), LIGHT (TNFSF14), TL1A/VEGI (TNFSF15), and GITR Ligand (TNFSF18). BAFF is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells.

The recombinant mouse protein BAFF has a predicted molecular weight of 20.6 kDa.

All IBI recombinant proteins are lyophilized and shipped at room temperature without carrier protein. Proteins can be reconstituted in sterile PBS with at least 0.1% of carrier protein such as BSA or cell assay media.

The BAFF mouse protein can be used in cell culture, as a BAFF ELISA Standard, and as a Western Blot Control.
