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: Embigin/EMB

Embigin (EMB) is a transmembrane glycoprotein belonging to the immunoglobulin superfamily (IgSF) proteins. It is a cell adhesion molecule that is preferentially expressed during mouse embryogenesis (1). Embigin, along with basigin and neuroplastin, form a small subgroup within the IgSF, with all members possessing a glutamate at the same position in the transmembrane domain (2). Mature, human Embigin is highly glycosylated and consists of an extracellular domain (ECD) wjth two Ig domains, a transmembrane region, and a short intracellular region. Within the ECD, human EMB shares 75% and 62% amino acid identity with mouse and rat EMB, respectively. Embigin is an accessory protein of monocarboxylic acid transporter, MCT2 which participates in transporting lactic acid between glial cells and neurons (3). Thus, it may be related to brain energy metabolism and has been investigated as a susceptible gene for schizophrenia (4). Embigin is highly expressed in early embryos of mice, and in the heart, lung, brain and other tissues of adult rats (5, 6). Loss of embigin promotes proliferation, anchorage-independent growth, and migration ability of breast cancer cells (7).
