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 250 μg/mL in PBS.

Background: CDCP1

CDCP1 (CUB-domain containing protein 1; also known as CD318 and SIMA135) is a novel, 135 kDa cell surface glycoprotein that is found on tumor, stem cells, keratinocytes and colonic epithelial cells (1). It is reported that this protein is over-expressed in colon and lung cancers. CDCP1 is a type I transmembrane (TM) protein that is involved with cell adhesion. Mouse CDCP1 is synthesized as an 833 amino acid (aa) precursor. It contains an extracellular region with three CUB domains (aa 30‑667) and a phosphotyrosine site at Tyr731. The phosphorylation state of CDCP-1 has an effect on anchorage in epithelial cells (2). When unligated, CDCP1 can be proteolytically cleaved between aa 270‑300. This generates an 80 kDa TM protein that may be missing the N-terminal CUB domain (aa 221‑350) (3). Over aa 25‑667, mouse CDCP1 is 83% and 92% aa identical to human and rat CDCP1, respectively.
