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: PSGL-1/CD162

PSGL-1 (P-Selectin Glycoprotein Ligand-1, designated CD162), is a 110-120 kDa mucin-type glycoprotein that plays a key role in leukocyte adhesion (1-3). Human PSGL-1 cDNA encodes 412 amino acids (aa) including a 17 aa signal sequence, a 24 aa propeptide, a 279 aa extracellular domain (ECD), a 21 aa transmembrane segment and a 71 aa cytoplasmic region (1). The ECD of human PSGL-1 contains 16 decameric repeats in the A allele (long form), which is expressed by 65-80% of the population. Alleles B and C contain 15 and 14 repeats, respectively, and mouse PSGL-1 contains 10-12 repeats (1, 3). Shorter forms may show weaker binding to P-selectin (9). Human PSGL-1 ECD shares less than 50% aa sequence identity with mouse, equine, canine and porcine PSGL-1 ECD. However, all share structural motifs and functions (1-3). The mature PSGL-1 (aa 42-412) is expressed as a disulfide-linked homodimer that signals intracellularly and promotes integrin activation (2‑4). Ligand binding relies on presence of O-glycosylation/sialylated Lewis X (LeX) and tyrosine sulfation within aa 42-57 (1, 5-7). Sulfation and glycosylation, which are constitutive on neutrophils and induced with activation on T cells, are essential for binding to P-selectin and L-selectin (3-6). E-Selectin requires only glycosylation (3). Proteases such as neutrophil elastase and cathepsin G can cleave within this region, impacting binding affinity (3, 8). Cleaved, soluble ectodomains of PSGL-1 are also known (3). PSGL-1 is found on virtually all leukocytes, dendritic cells, platelets, and some endothelial cells (3). It is primarily responsible for early events in extravasation, especially rolling adhesion of leukocytes to vascular endothelium (3, 4). In addition, PGSL-1 binds chemokines such as CCL19, CCL21 and CCL27, promoting chemotaxis of hematopoietic stem cells and plasma cells to the bone marrow and T cell homing to lymphoid organs (3, 10, 11). Recombinant PSGL-1 ECD interferes with this chemotaxis (13). PSGL-1 binds von Willebrand factor in endothelial-derived Weibel-Palade bodies, and the chondroitin sulfate, versican (3). It is present with Tissue Factor in pro-thrombotic microparticles from membranes of monocytes and cancer cells, and is required for particle shedding and fusion with activated platelets (12, 13).
