Recombinant Human Cerebellin-2 Protein, CF Summary

>85%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin Level
<1.0 EU per 1 μg of the protein by the LAL method.
Measured by its binding ability in a functional ELISA. When Recombinant Human Cerebellin-2 is coated at 5 μg/mL, biotinylated recombinant rat NRXN-1 beta binds with an apparent KD <1.5 nM. Measured by its ability to enhance neurite outgrowth of E16-E18 rat embryonic cortical neurons. Recombinant Human Cerebellin-2, immobilized at 3-30 μg/mL, is able to significantly enhance neurite outgrowth.

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.
Reconstitution Reconstitute at 200 μg/mL in PBS.

Background: Cerebellin-2

Cerebellin-2 (CBLN2) is an approximately 25 kDa N-glycosylated protein in the Cerebellin family of TNF superfamily molecules (1). Cerebellins contain a collagenous domain and a C-terminal TNF/C1q-like domain. Human Cerebellin-2 consists of this 175 amino acid (aa) region following an N-terminal 28 aa potential cytoplasmic domain and a 21 aa potential transmembrane segment. Within the Cerebellin-like region, human Cerebellin-2 shares 99% aa sequence identity with mouse, rat, and chick Cerebellin-2 (2‑4). It is expressed in multiple regions of the nervous system including the neocortex, olfactory bulb, thalamus, hypothalamus, midbrain (5), preganglionic sensory nerves, dorsal root ganglia, and sensory and motoneurons of the spinal cord (4, 6) as well as in the zona glomerulosa of the adrenal cortex (7). Cerebellin-2 forms cell associated homo-oligomers and heteromers with Cerebellins-1, -3, and -4 [Iijima 1049]. It binds with high affinity to alpha and beta Neurexin 1 isoforms that contain the splice site 4 insert (+SS4) and more weakly to Neurexin 2 beta (+SS4) and Neurexin 3 beta (+SS4) (9, 10). These interactions promote presynaptic differentiation in cultures of cortical and cerebellar neurons (9, 10).
