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.


Formulation Lyophilized from a 0.2 μm filtered solution in PBS.

Background: IL-13 R alpha 2

Interleukin-13 Receptor alpha 2 (IL-13 Ra2), also known as IL-13 Ra’, IL-13 binding protein, and CD213a2, is a widely expressed 55 kDa cytokine receptor that plays an important role in the Th2‑polarized immune responses characteristic of a variety of pathologies including parasitic infections and allergic asthma (1, 2). Mature mouse IL-13 Ra2 consists of a 313 amino acid (aa) extracellular domain with three fibronectin type-III domains, a WSxWS motif, a 21 aa transmembrane segment, and a 28 aa cytoplasmic domain (3). Within the ECD, mouse IL-13 Ra2 shares 64% and 94% aa sequence identity with human and rat IL-13 Ra2, respectively. A 40 kDa ‑ 50 kDa soluble form of mouse IL-13 Ra2 can be generated by alternate splicing or MMP-8 mediated shedding (4, 5). The biological effects of IL-13 and IL-4 are closely related in part due to a shared receptor system. IL‑13 binds to IL-13 Ra1 which then forms a signaling complex with IL-4 Ra (6, 7). IL-13 Ra2 functions as a decoy receptor by binding and internalizing IL-13 and preventing it from signaling through the IL-13 Ra1/IL-4 Ra complex (3, 8). IL‑13 Ra2 can also block IL-4 induced responses by inhibiting IL-4 bound IL-13 Ra1/IL-4 Ra receptor complexes even though it does not itself bind IL-4 (9, 10). Aside from its decoy function, IL‑13‑activated IL-13 Ra2 directly promotes the development of tissue fibrosis by inducing the transcription of TGF-beta (11). Soluble IL‑13 Ra2 retains ligand binding capability and attenuates responses to IL-13 but not to IL-4 (9, 12). The up‑regulation of transmembrane and soluble IL‑13 Ra2 during Th2-biased immune responses limits the extent of those responses (13 ‑ 15). IL‑13 Ra2 is expressed in some cancers, and its ability to block IL-13 and IL-4 contributes to tumorigenesis and metastasis (10, 16).
