Recombinant Human Thrombospondin-1 Protein, CF Summary

Product Specifications

Purity
>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by its binding ability in a functional ELISA. When Recombinant Human VEGF (Catalog # 8147-VE/CF) is coated at 1.00 μg/mL (100 μL/well), it binds to Recombinant Human Thrombospondin‑1. The ED50 for this binding is 100-600 ng/mL.

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: Thrombospondin-1

Thrombospondin-1 (TSP-1) is a 150-180 kDa calcium-sensitive protein that is secreted as a disulfide-linked homotrimer. Within the Thrombospondin family, TSP-2 is also homotrimeric, while TSP-3, -4, and -5/COMP are homopentameric. TSP-1 regulates a wide range of cellular functions including their interactions with other cells and with the extracellular matrix (ECM). TSP-1 contains an N-terminal Laminin G-like globular domain, an extended central region with one vWFC domain, 3 TSP type 1 domains, 2 EGF-like domains, and 8 TSP type-3 domains, and a globular TSP C-terminal domain. Distinct regions of TSP-1 have been associated with binding to particular ECM or cellular molecules (1, 2). Mature human TSP-1 shares 95% amino acid sequence identity with mouse and rat TSP-1. TSP-1 counteracts the angiogenic, hypotensive, and anti-thrombotic effects of nitric oxide (NO) (3). It binds and neutralizes VEGF, blocks VEGF R2 signaling on vascular endothelial cells (EC), and destabilizes adhesive contacts between EC (4-6). TSP-1’s actions on vascular smooth muscle cells support arterial tone and blood pressure in the presence of vasodilatory stimulation (7). It is released from activated platelets and enhances platelet aggregation and adhesion (8). TSP-1 also plays an important role in wound repair and tissue fibrosis by binding latent TGF-beta and inducing release of the active cytokine from the latency associated peptide (LAP) (9, 10). TSP-1 dampens adaptive immune responses by inducing the differentiation of regulatory T cells and inhibiting TCR signaling (11, 12). In the nervous system, it promotes excitatory synapse formation (13, 14) and supports the integration of neural progenitor cells into the olfactory bulb (15). In addition, TSP-1 is released by apoptotic cells and promotes macrophage-mediated debris clearance (16).

Recombinant Human Thrombospondin-1 Protein, CF
By Anonymous on 10/04/2019
Application: Immunoassay Standard

We used this protein for a sandwich ELISA in combination with mAb (MAB3074)) and pAb (AF3074). This combination works very well for detecting the TSP1 in human serum and plasma samples.
