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: THSD7A

Thrombospondin type I domain containing 7A, also known as THSD7A, is an approximately 250 kDa type I membrane protein (1). THSD-7A has a large extracellular domain containing ten thrombospondin type 1 repeats, six WSXW motifs, one RGD motif, and fourteen predicted N‑glycosylated sites (1). Mature THSD7A shares 91% and 92% amino acid sequence identity with mouse and rat, respectively. THSD7A is expressed in podocytes, glomerular endothelial cells and mesangial cells (2). It is a novel neural protein known to affect endothelial migration and vascular patterning during development (1, 3). Soluble THSD7A promotes endothelial filopodia formation and focal adhesion assembly and induces FAK-dependent signaling during angiogenesis (1). THSD7A can co-localize with aVb3 integrin in HUVECs (3). Additionally, most recent study has indicated that THSD7A is associated with obesity (4).
