Recombinant Human Angiopoietin-like 7 Biotin Protein, CF Summary
Gln27-Pro346, with a C-terminal 10-His tag
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.
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.

Both Biotinylated rhANGPTL7 (Catalog # BT914) and unlabeled Recombinant Human Angiopoietin-like Protein 7/ANGPTL7 (Catalog # 914-AN) stimulate the expansion of E16-E18 rat liver mononuclear cellsin vitro, in the presence of Recombinant Mouse SCF/c-kit Ligand (Catalog # 455-MC), Recombinant Mouse Thrombopoietin/Tpo (Catalog # 488-TO), and Recombinant Mouse Flt-3 Ligand (Catalog # 427-FL). The ED50for this effect is 50-200 ng/mL in the presence of a cross-linking antibody, His Tag MAb (Catalog # MAB050). The similarity in activity highlights that the biotinylated protein is fully functional.
Background: Angiopoietin-like Protein 7/ANGPTL7
Angiopoietin-like 7 (ANGPTL7), also known as Corneal-Derived Transcript 6 (CDT6), is a secreted glycoprotein that is structurally related to the angiopoietins. Members of this protein family contain an N-terminal coiled coil domain and a C-terminal fibrinogen-like domain (1-3). ANGPTL7 shares 89% aa sequence identity with mouse and rat ANGPTL7. It is secreted as a 45-50 kDa monomer that forms disulfide-linked homotrimers and tetramers via the coiled coil domain (4, 5). ANGPTL7 is expressed in the corneal stroma, trabecular meshwork, and sclera and is elevated in glaucoma aqueous humor (3, 5). Its production is up-regulated in trabecular meshwork cells by glucocorticoids and TGF-beta and in cartilage by TNF-alpha (5-7). Over-expression of ANGPTL7 in trabecular meshwork cells inhibits the production of collagen and proteoglycans (8). When over-expressed in tumor cells it promotes collagen and proteoglycan deposition but inhibits tumor xenograft progression and tumor angiogenesis (4). ANGPTL7, when used in combination with SCF, Thrombopoietin, IGF-II, and FGF acidic, enhances the expansion and engraftment of human and mouse hematopoietic stem cells (9).
