Analysis
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: CLEC10A/CD301
CLEC10A, also known as macrophage galactose/N-acetyl-galactosamine (GalNAc) specific lectin (MGL), CD301, DC-ASGPR, and HML, is a 40 kDa type II transmembrane glycoprotein in the C-type lectin family (1). Human and rat carry a single gene for CLEC10A/MGL, while mouse has two closely related MGL1 and MGL2 genes. Rat CLEC10A consists of a 37 amino acid (aa) cytoplasmic region, a 21 aa transmembrane segment, and a 248 aa extracellular domain (ECD) with one carbohydrate recognition domain and a neck region (2). Within the ECD, rat CLEC10A shares 56% and 79% aa sequence identity with human CLEC10A and mouse CLEC10A/MGL1, respectively. CLEC10A is expressed on immature myleloid dendritic cells, Langerhans cells, and alternatively activated (tolerogenic) macrophages and is upregulated by the immunosuppressant dexamethasone (3-8). It is up-regulated on pro-inflammatory monocytes in obesity and promotes their trafficking to adipose tissue (9). CLEC10A selectively binds and internalizes terminal nonsialylated alpha - or beta -linked GalNAc moieties on O-linked carbohydrates including the Tn carcinoma antigen (3, 4, 10-12). Similar ligand preference is exhibited by mouse MGL2 but not MGL1 (13). CLEC10A expressed on tolerogenic dendritic cells binds carbohydrate determinants on CD45 (RA, RB, and RC but not RO isoforms) on T, NK, and B cells (6). This interaction inhibits effector T cell activation and induces their apoptosis (6). CLEC10A also binds the GP envelope glycoprotein on Marburg and Ebola viruses and enhances viral entry and infectivity (14).
