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: ULBP-1
MULT-1 (mouse UL16-binding protein-like Transcript 1) is a 53 kDa, MHC Class I-like molecule that belongs to the mouse family of NKG2D ligands (1-4). It is a type I transmembrane glycoprotein that is synthesized as a 334 amino acid (aa) precursor. It contains a 25 aa signal sequence, a 186 aa extracellular region, a 19 aa transmembrane segment and a 104 aa cytoplasmic tail (2). The extracellular region contains an alpha-1 and alpha-2 like domain with two intrachain disulfide bonds. MULT-1 is distantly related to other human and mouse NKG2D ligands, and more distantly related to the MHC class I proteins (3). Unlike most NKG2D ligands, transcripts for MULT-1 have been detected in a wide variety of mouse tissues and tumor cells lines (3). The receptor for MULT-1 is NKG2D, a 35 kDa C-type lectin that is found on mouse NK cells, activated CD8+ T cells, epidermal gamma δ T cells, and activated macrophages (1, 5, 6, 7). Recombinant MULT-1 protein binds to NKG2D with high affinity (Kd = 6 nM) (2). Although an activating receptor, general cellular responses to NKG2D ligation depend upon the isoform of NKG2D and the cell type (5). Little is known about the specific MULT-1-NKG2D association. Exposure to immobilized MULT-1 or MULT-1-transfected cells elicits IFN-gamma production by NK cells (3). Ectopic expression of MULT-1 on the RMA mouse tumor cell line leads to tumor rejection in syngeneic mice (3).
