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.

Background: CDCP1

CDCP1 (CUB-domain containing protein 1), also known as Trask or CD318, is a type I transmembrane receptor whose specific role remains unclear. Human CDCP1 is synthesized with a large extracellular domain (ECD) containing three CUB domains, a transmembrane domain and a cytoplasmic domain with 5 tyrosine phosphorylation sites (1). Full-length CDCP1 is ~135 kDa and can be cleaved into a ~70 kDa membrane-bound and a ~65 kDa circulating form (2). A secreted only form of human CDCP1, also called Isoform 2, can also be expressed consisting of amino acids (aa) 30-343 of the ECD (3). Mature human Isoform 2 shares 86% and 85% aa sequence identity to mouse and rat CDCP1 Isoform 2, respectively. CDCP1 was originally identified from proteins involved in metastasis and has been found on tumor, stem cells, keratinocytes and colonic epithelial cells (1). Tyrosine phosphorylation of the intracellular domain of CDCP1 results in downstream signaling through Src-family kinases (SFKs), Akt, and PKCδ (2, 4, 5). CDCP1 appears to be important for cell-cell and cell-substratum adhesion and the phosphorylation state of CDCP1 regulates this effect (5, 7). CDCP1 is associated with a poor prognosis in epithelial tumors, such as lung, pancreatic, colorectal, renal, and ovarian carcinomas (rEf) and is a novel marker of the most aggressive human triple-negative breast cancers (7, 8). Several different extracellular forms of CDCP1 have been shown to exhibit disease-specific expression in prostate cancer (9).
