Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: TRAIL R2/TNFRSF10B

Mouse TRAIL R2, also called DR5, TRICK 2, TNFRSF10B, and MK is a type 1 TNF R superfamily, membrane protein which is a receptor for TRAIL (APO2 ligand). Mouse TRAIL R2 cDNA encodes a 381 amino acid residue precursor protein containing an extracellular cysteine-rich domain, a transmembrane domain and a cytoplasmic death domain. Human and mouse TRAIL R2 share 49% amino acid sequence similarity. The death domains of human TRAIL R1 and TRAIL R2 share high homology with the death domain of mouse TRAIL R2, 76% and 79%, respectively. Binding of trimeric TRAIL to TRAIL R2 induces apoptosis. The induction of apoptosis likely requires oligomerization of the receptor. The mouse TRAIL R2/Fc chimera neutralizes the ability of rhTRAIL to induce apoptosis. Besides the death domain containing receptors TRAIL R2 and TRAIL R1/DR4, three TRAIL decoy receptors, TRAIL R3/DcR1, TRAIL R4/DcR2, and OPG, have been reported.

FAQs

  1. This protein datasheet indicates I need to use a cross-linking antibody, Catalog # MAB050, for biological activity. What is this antibody and is it really necessary?

    • The antibody is directed against a 6x histidine repeat and is recommended for use as a cross-linker of proteins with 6x his-tag. Crosslinking is often used for proteins that require receptor trimerization and can result greater biological activity. R&D Systems Quality Control tests the performance of these proteins in the presence of the cross-linking antibody. Therefore, it is necessary to use this antibody when trying to achieve the same level of specific activity described in the datasheet.
