Formulation, Preparation and Storage
What does CF mean?
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our
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

Reversion-inducing cysteine-rich protein with Kazal motifs (RECK), also known as Suppressor of tumorigenicity 15 protein (ST15), is a 971 amino acid highly conserved protein that serves as an important mediator of tissue remodeling (1). The multi-domain protein includes hydrophobic regions at the N- and C-termini that correspond to a signal domain and GPI anchoring site, respectively (2). Internally, there are three serine protease inhibitor-like (SPI) domains and two regions with EGF-like repeats (2). The N-terminal region also contains a cysteine-rich domain essential for MMP (3) and Wnt7 binding (4, 5). RECK is normally expressed in all human and mammalian cells (2, 6) while undetectable or downregulated in malignant and cancer cells (1, 2). There is a strong correlation with expression of RECK in several cancers including colorectal, breast, and pancreatic making it a prognostic marker of interest (1, 3, 7-9). Polymorphisms in RECK leads to increased cancer susceptibility (10). RECK's ability to bind several proteins confers complex functionality. RECK is known to bind and inhibit MMPs (1, 2, 11), interact with ADAMTS10 (12), modulate Notch signaling (13), promote p53 signaling (14) and act as a selective Wnt7 receptor through binding of Gpr124 (4). RECK acts as a tumor suppression gene by inhibiting angiogenesis, invasion, and metastasis through its role in the regulation and signaling within the extracellular matrix (1, 3, 6). Through its interaction with Wnt7, RECK promotes angiogenesis and regulates the blood-brain barrier in CNS by mediating canonical Wnt/beta-catenin signaling (4).
