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.


Formulation Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Reconstitution Reconstitute at 1 mg/mL in PBS.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.

Background: LINGO-1

LINGO-1 (Leucine-rich repeat and immunoglobulin-like domain-containing Nogo receptor-interacting protein 1), also known as LERN1 (Leucin-rich repeat neuronal protein 1) or LRRN6A (Leucine-rich repeat neuronal protein 6A), is a 614 amino acid (aa) transmembrane protein of the leucine-rich repeat (LRR) family, ribonuclease inhibitor subfamily (1). The four known LINGO proteins (LINGO-1, -2, -3 and -4) contain LRR and IgCAM domains in the extracellular portion and share 44‑61% aa identity (2). LINGO-1 is restricted to the nervous system and is concentrated in the brain as a component of the NgR1/p75 and NgR1/Taj (TROY) signaling complexes (3). LINGO-1 negatively regulates neurite outgrowth and myelination. LINGO-1 is highly conserved, showing 99% aa identity between human, mouse and rat (2, 4). LINGO-1 promotes lysosomal degradation of amyloid-beta protein precursor and acts as a key player in Alzheimer's Disease progression (5). It suppresses oligodendrocyte precursor cell and myelin maturation, which leads to neurodegeneration (6). The intracellular LINGO-1 negatively regulates Trk receptors' signaling by modulating their lysosomal degradation (7). Inhibition of LINGO-1 may protect against degeneration of dopamine neurons in Parkinson's disease (8).
