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 500 μg/mL in PBS.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.

Background: SLITRK4

SLITRK4 is an approximately 90 kDa type I transmembrane member of the SLITRK family of proteins which contain a slit-like extracellular region and a Trk-like cytoplasmic region (1). Within the extracellular domain (ECD), the mouse SLITRK4 shares 98% amino acid sequence identity with human SLITRK4. The ECD of SLITRK4 contains 6 leucine rich repeats (LRR) followed by a C-terminal LRR domain, and 6 more LRRs flanked by a pair of N- and C-terminal LRR domains (2, 3). SLITRK4 is expressed in the testis and multiple regions of the brain, particularly the cerebral cortex, cerebellum, and hippocampus (4). SLITRK4 can suppress neurite outgrowth and promote the formation of excitatory presynaptic structures (3, 5). SLITRK genes are also differentially expressed in brain tumors, including astrocytoma, oligodendroglioma, glioblastoma, medulloblastoma, and supratentorial primitive neuroectodermal tumor (PNET) (2).
