RANK was initially cloned from dendritic cells. It is a type I membrane 66 kD protein that is expressed in monocytes, macrophages, dendritic cells, osteoclast precursors, and among other cells. RANK and its ligand (RANKL) play a key role in bone homeostasis, organogenesis, immune tolerance, and cancer. RANK and RANKL are members of the TNF family and are respectively designated as TNFRSF11A and TNFSF11. RANK, as well as other TNF receptor members, lacks intrinsic enzymatic activity. Its signal transduction is carried out by the recruitment of various adaptor proteins, including TNFR-associated factors (TRAFs), leading to the activation of JNK, ERK, p38, NFATc1, AKT, and NF-κB signaling pathways. In addition, IFN-γ, IFN-β, and ITAM-activated costimulatory signals crosstalk with RANK signaling to regulate osteoclastogenesis in the opposite manner. While IFN-γ and IFN-β inhibit, ITAM stimulates this process. RANK and its ligand are associated to bone diseases such as postmenopausal osteoporosis and bone loss in inflammatory conditions. RANKL expressed on activated T-cells induces bone loss and joint destruction in rheumatoid arthritis. Also, RANK provides signals during medullary thymic epithelial cells (mTEC) development. mTECs contribute to the selection and survival of immunosuppressive Foxp3-positive regulatory T cells.

- Concentration
- 25 µg size is bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.

- Why choose BioLegend recombinant proteins?
-
• Each lot of product is quality-tested for bioactivity as indicated on the data sheet.
• Greater than 95% Purity or higher, tested on every lot of product.
• 100% Satisfaction Guarantee for quality performance, stability, and consistency.
• Ready-to-use liquid format saves time and reduces challenges associated with reconstitution.
• Bulk and customization available. Contact us.
• 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)
