Human TNFRSF10A inhibits the cytotoxic effect induced by recombinant human TRAIL on mouse L929 cells. -
Human TNFRSF10A was aliquoted in PBS, pH 7 at 0.1 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 cytotoxic effect induced by recombinant human TRAIL on mouse L929 cells.

TNFRSF10A, also called TRAIL R1 and DR4, is a member of the TNF receptor superfamily. It contains a cysteine-rich extracellular domain, a transmembrane domain and an intracellular death domain, which mediates interactions between death receptor and death domain-containing adaptor proteins. When the trimeric ligand TRAIL (TNFSF10) is bound, homotrimer TNFRSF10A interacts with the adaptor protein Fas-associated death domain (FADD), in turn recruits caspase-8 and assembles a death-inducing signaling complex (DISC) that initiates apoptosis. There are decoy receptors, TRAIL R3 (DcR1), TRAIL R4 (DcR2) and OPG, which antagonize the apoptotic effect via competitive ligand binding. Human TNFRSF10A shows 52% identity to human TNFRSF10B and there is some functional redundancy. Several evidences indicated that TNFRSF10A play roles in tumorigenesis and DNA damage response. Some studies indicated the role of TNFRSF10A in cancer predisposition. A rare allele of TNFRSF10A was found to be more frequent in chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), prostate cancer, bladder cancer, colorectal cancer and head and neck squamous cell carcinoma (HNSCC). Agonistic monoclonal antibodies against TNFRSF10A, which can induce apoptosis in the absence of TRAIL, are used for cancer therapies. However, some studies have suggested that TNFRSF10B contributes more than TNFRSF10A to TRAIL-induced apoptosis in cancer cells that express both receptors. The expression of TNFRSF10A is inducible and up-regulated by DNA damage in p53-dependent manner.

• 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)
