Human TNFRSF12A inhibits the proliferation induced by TNFSF12 (TWEAK) in HUVEC cells. -
Human TNFRSF12A was aliquoted in PBS, pH 7 at 0.2 mg/ml and one aliquot was kept at 4°C (control), and another was freeze/thawed four times (4x freeze/thaws). After this procedure, the samples were tested for their ability to inhibit the proliferation of HUVEC cells induced by TNFSF12 (TWEAK).

TNFRSF12A was initially identified as a fibroblast growth factor-1-inducible gene in murine NIH 3T3 cells, and was named as fibroblast growth factor-inducible-14 (Fn14) gene. Human TNFRSF12A was cloned from a HUVEC cDNA library and identified as the TWEAK receptor and a member of the TNFR family. It is a type-I transmembrane protein of 128 amino acids in length and has a cysteine rich region in the extracellular domain and a TRAF-binding motif in the intracellular domain. TNFRSF12A binds to TRAF2 (TRAFs 1, 3, and 5) in yeast two-hybrid screen and can initiate both canonical and noncanonical NF-κB activation. Also, TNFRSF12A-TNFRSF12 signaling induces lysosomal degradation of a cIAP1–TRAF2 complex to sensitize tumor cells to TNFRSF12A and its ligand trigger proliferation of mesenchymal progenitor cells and inhibit differentiation of chondrocytes, osteoblasts, and myocytes. TNFRSF12A expression is upregulated on epithelial and mesenchymal progenitor cells after tissue damage induced by including hypoxia, oxidative stress, chemical and mechanical injuries, inflammation, and tumor growth. TNFRSF12A and its ligand play a key role in muscle atrophy, cerebral ischemia, kidney injury, atherosclerosis, experimental autoimmune encephalitis, rheumatoid arthritis, and inflammatory bowel disease.

- Application Notes
-
BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue-ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are verified in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee.

• Learn more about our Recombinant Proteins. - How does the activity of your recombinant proteins compare to competitors?
-
We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!
- What is the specific activity or ED50 of my recombinant protein?
-
The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.
- Have your recombinants been tested for stability?
-
Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.
- Does specific activity of a recombinant protein vary between lots?
-
Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.
- How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
-
Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
