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: L-Selectin/CD62L

L-Selectin, also known as Leukocyte adhesion molecule 1 (LAM‑1) and CD62L, is a type-1 cell surface glycoprotein and cell adhesion molecule of the Selectin family (1). In humans, there are 3 Selectins, P, E, and L, and they are Ca2+ dependent lectins that help mediate the initial adhesive step during inflammation and immune surveillance (2). Mature L-Selectin consists of an extracellular domain (ECD) with a C-type lectin domain and an epidermal growth factor (EGF)-like domain, a transmembrane domain, and a short cytoplasmic domain. Within the ECD, cynomolgus L-Selectin shares 94% amino acid sequence identity with human L-Selectin. Several isoforms arising from alternative splicing have been reported, some with potential therapeutic implications (2,3). L-selectin is constitutively expressed on a wide variety of leukocytes and plays a role in the migration of lymphocytes into peripheral lymph nodes and sites of chronic inflammation, and of neutrophils into acute inflammatory sites (1-4). Acting in cooperation with P-Selectin and E-Selectin, L‑Selectin mediates the initial interaction of circulating leukocytes with endothelial cells that produces a characteristic "rolling" of the leukocytes on the endothelium (5). This initial interaction, also involving ICAM-1 and VCAM-1, leads eventually to extravasation of the white blood cell through the blood vessel wall into the extracellular matrix tissue (6). L-selectin function is required for normal Treg cell migration and over expression might be result in reduced tumor growth (7). A number of studies have reported that levels of L‑Selectin may be elevated or lowered in subjects with a variety of conditions, such as in Alzheimer's disease or rheumatoid arthritis (3, 5).
