Polyclonal Goat IgG
Protein A or G purified
S. frugiperda insect ovarian cell line Sf 21-derived recombinant human PD-ECGF/Thymidine Phosphorylase
Accession # P19971.2
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Western Blot
1 µg/mL
Recombinant Human PD-ECGF (Catalog # 229-PE)
Measured by its ability to neutralize PD‑ECGF-induced proliferation in HUVEC human umbilical vein endothelial cells. Usuki, K. et al. (1990) Cell Regulation 1:577. The Neutralization Dose (ND50) is typically 10-25 µg/mL in the presence of 150 ng/mL Recombinant Human PD‑ECGF.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Proliferation Induced by PD‑ECGF/Thymidine Phosphorylase and Neutralization by Human PD‑ECGF/Thymidine Phosphorylase Antibody. Recombinant Human PD-ECGF/Thymidine Phosphorylase (Catalog # 229-PE) stimulates proliferation in HUVEC human umbilical vein endothelial cells in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human PD-ECGF/Thymidine Phosphorylase (150 ng/mL) is neutral-ized (green line) by increasing concentrations of Goat Anti-Human PD-ECGF/Thymidine Phosphorylase Polyclonal Antibody (Catalog # AB-229-NA). The ND50 is typically 10-25 µg/mL.

Background: PD-ECGF/Thymidine Phosphorylase

PD-ECGF, also known as TPase and gliostatin, is produced by placenta, platelets, liver, lung, spleen, lymph nodes, and peripheral lymphocytes. It is overexpressed by many tumors in response to chemical or physical stress. PD-ECGF promotes endothelial cell proliferation and chemotaxis and promotes angiogenesis. PD-ECGF is a key enzyme in the pyrimidine nucleoside salvage pathway. It also metabolizes and inactivates chemotherapeutic drugs such as 5-fluorouracil and its derivatives. The human PD-ECGF cDNA encodes a 482 amino acid (aa) polypeptide with a 10 aa propeptide. The protein is localized mostly within the producer cells. N-terminal truncation, resulting in proteins lacking 10 aa and 6 aa, has been observed in PD-ECGF purified from platelets and placenta, respectively. In solution, PD-ECGF exists as a non-disulfide linked homodimer. The latter protein was purified from quiescent astrocytes and described as an astrocyte and astrocytoma cell growth inhibitor based on its ability to inhibit 3H-thymidine incorporation.
