Recombinant Human LRP-1 Cluster III Fc Chimera Protein, CF
Recombinant Human LRP-1 Cluster III Fc Chimera Protein, CF Summary
When recombinant human (rh) LRP‑1 Cluster III Fc Chimera is immobilized at 50 ng/mL (100 μL/well), the concentration of rhLRPAP (Catalog # 4296‑LR) that produces 50% of the optimal binding response is found to be approximately 1-5 ng/mL.

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.

Background: LRP-1 Cluster III
LDL receptor-related protein 1 (LRP-1), also known as CD91 and the alpha 2-macroglobulin receptor, is a type I membrane protein in the LDL receptor superfamily. It is expressed on neurons, hepatocytes, adipocytes, vascular smooth muscle cells, fibroblasts, keratinocytes, macrophages, and megakaryocytes. LRP-1 is important for the clearance of a large number of circulating molecules involved in fatty acid metabolism and complexes of serine proteases with their inhibitors (1 - 4). LRP-1 also associates directly or through intracellular scaffold proteins with other membrane associated proteins on the same cell. This allows LRP-1 to modulate the activity or internalization of PDGF R beta, NMDA receptor subunits, TGF-beta receptors, Frizzled‑1, various integrins, and the prion protein PrPC (1, 5 ‑ 10). Human LRP-1 is an N‑glycosylated and sialylated molecule that is cleaved in the Golgi to produce an 85 kDa transmembrane beta chain and a 515 kDa alpha chain that associates noncovalently with the beta chain but does not itself cross the membrane (11, 12). The alpha chain of LRP-1 contains 31 LDLR class A repeats, 34 LDLR class B repeats, and 22 EGF‑like repeats (13). The LDLR domains are clustered in four regions throughout the protein (13). LRP-1 Cluster III (aa 2522 ‑ 2941) contains ten LDLR-A cysteine-rich domains (14). Within this region, human LRP-1 shares 97% aa sequence identity with mouse and rat LRP-1. A soluble form of LRP-1 is shed into the serum and cerebrospinal fluid and retains ligand binding properties (15, 16). LRP-1 Cluster III contains binding sites for LRPAP/RAP (14).
