- Predicted molecular weight: 16.4 kDa
- No endotoxins, TAGS, and carrier-free
- Naturally folded and post-translationally modified
IBI recombinant proteins are expressed in Pichia pastoris (yeast) system which provides many advantages over E. coli systems. 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.
APRIL or tumor necrosis factor ligand superfamily member 13 (TNFSF13) 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).
APRIL/TNFSF13 is expressed by macrophages and dendritic cells. APRIL/TNFSF13 has been shown to play a role in protecting cells from undergoing apoptosis and promoting B cell development.
The recombinant mouse protein APRIL has a predicted molecular weight of 16.4 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 APRIL mouse protein can be used in cell culture, as an APRIL ELISA Standard, and as a Western Blot Control.
