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: Kirrel3/NEPH2
Kirrel3 (kin of irregular chiasm-1-like 3), also known as Kirre or NEPH2 (nephrin-like 2), is an ~100 kDa type I transmembrane glycoprotein belonging to the NEPH family within the immunoglobulin superfamily (1, 2). The three Kirrel/NEPH proteins share 34 - 44% amino acid (aa) identity, and all interact with nephrin, podocin and the adaptor molecule ZO-1 (1, 4). While all can be found in podocytes of the kidney glomerulus, Kirrel3 has been mainly studied in the brain and bone marrow (2 - 6). Human Kirrel3 cDNA encodes a 778 aa protein that contains a 21 aa signal sequence, a 514 aa extracellular domain with five C2-type Ig-like domains, a 21 aa transmembrane sequence and a 222 aa intracellular domain (7). The extracellular domain of human Kirrel3 shares 98%, 96%, 95% and 99% aa identity with mouse, rat, canine and bovine Kirrel3, respectively. One isoform diverges after the transmembrane domain and is truncated prior to conserved podocin-binding and PDZ cytoplasmic motifs (1 - 4, 7). Metalloproteinase-mediated cleavage can release a soluble form of Kirrel3 from the cell surface (2, 3). In the brain, Kirrel3 is present with nephrin during development of sensory pathways (5, 6). In the adult mouse, Kirrel3 is present in resting olfactory neurons, but downregulated when they are activated (6, 8). In contrast, Kirrel2 is present in olfactory neurons only when they are active. This complementary expression is postulated to help coordinate nerves identifying the same odorant (8). Expression of Kirrel3 on bone marrow stromal cells is identified as a factor that supports maintenance of hematopoietic stem cells in an undifferentiated state (2).
