Recombinant human CD30-Fc chimera binds to immobilized recombinant human CD30L (Cat. No. 767102) in a dose-dependent manner. The ED50 for this effect is 2 – 8 ng/mL. -
Stability Testing for Recombinant Human CD30-Fc Chimera. Recombinant human CD30-Fc chimera was aliquoted in PBS, pH 7.2. One aliquot was frozen and thawed four times (4x Freeze/Thaw) and compared to the control that was kept at 4°C (Control). The samples were tested for their ability to bind to immobilized recombinant human CD30L (Cat. No. 767102) in a dose-dependent manner. The ED50 for this effect is 2 – 8 ng/mL.

Human CD30, a mature protein of 577 amino acids and a member of the TNF receptor family, is characterized by repeated cysteine-rich motifs in the extracellular domain. CD30 is a type I transmembrane glycoprotein, and it is expressed on some B cells and on mitogen-stimulated T cells. CD30 was originally identified as a cell surface antigen, Ki-1, on Hodgkin and Reed-Sternberg cells. CD30 binds to CD30L, a type II transmembrane protein, and the CD30-CD30L interaction induces NF-κB activation which is mediated by TNFR-associated factor 2 (TRAF2). CD30L/CD30 signaling seems to be involved in Th1 and Th2 cell responses and plays a key role in Th17 differentiation in mice. TNFRs such as CD30, OX40, and 4-1BB participate in survival of activated T cells. Mice lacking both OX40 and CD30 signals have severe loss of CD4+ memory T cells in the spleen and lamina propria. In addition, CD30-deficient mice show a decreased capacity to sustain follicular germinal center responses, and double KO mice (OX40 and CD30) lack memory antibody responses because of deficient CD4 T cell memory. Mast cells are the predominant CD30L-positive cell in chronic inflammatory skin diseases psoriasis and atopic dermatitis, and CD30 and CD30L expression is upregulated in lesional skin in these conditions. An agonistic anti-CD30 drug conjugate, Brentuximab vedotin, has been approved for the treatment of CD30-positive lymphomas.

• 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)
