Product Datasheets

Carrier Free

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.

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: IGFLR1

Insulin Growth Factor-like Family Receptor 1 (IGFLR1) is a 355 amino acid (aa) type 1a transmembrane protein that was identified in a screen for binding partners of human IGFL1 (1). Mature human IGFLR1 consists of an extracellular domain (ECD) with two putative cysteine-rich domains (CRDs), a transmembrane region, and a cytoplasmic domain (1). Its structure has similarities to TNF receptor family members (1).  The ECD contains 12 cysteine residues that are conserved among humans, macaque, mice, and rats (1). Over the first 163 aa, human IGFLR1 shares 61% and 59% aa sequence identity with mouse and rat IGFLR1, respectively. In mice, IGFLR1 is expressed primarily on T cells and, similar to the human proteins, mouse IGFLR1 binds the mouse IGFL protein (1). Human IGFL1 expression is enhanced by TNF-alpha treatment and was shown to be up-regulated in human psoriatic skin samples, suggesting that IGFLR1 may have a role during skin inflammation (1).
