BACKGROUND
Heparanase is an endo-β-D-glucuronidase, which degrades heparan
sulfate side chains of heparan sulfate proteoglycans (HSPGs) in the
extracellular matrix. Heparanase plays an important role in ECM
degradation, facilitating the migration and extravasation of tumor cells
and inflammatory leukocytes (1,2,3). Upon degradation, Heparanase
releases growth factors and cytokines that stimulate cell proliferation
and chemotaxis (4,5).
Heparanase is a heterodimer comprised of a 50 kDa subunit harboring
the active site and an 8 kDa subunit. It is produced as a latent 65 kDa
precursor and proteolytically processed to its active form (1,6).
Heparanase is highly expressed in myeloid leukocytes (i.e.
neutrophils) in platelets and in human placenta. Human Heparanase
was found to be upregulated in various types of primary tumors,
correlating in some cases with increased tumor invasiveness and
vascularity and with poor prospective survival (7,8).
SOURCE
Mab HP130 is a Protein G affinity purified monoclonal antibody
raised against the 65 kDa Heparanase precursor. It recognizes the Cterminal
region of both the latent pro-Heparanase and the active
heterodimeric enzyme.

PERFORMANCE
A. Reduced LDS-PAGE of Mab HP130
Monoclonal anti-human Heparanase-1 (HPA1) antibody clone HP130
(4 μg) was separated on a 12% bis-Tris SDS-polyacrylamide gel
electrophoresis (NuPage, Invitrogen) followed by GelCode Blue®
(Pierce) staining. Sample was prepared with DTT (reducing
conditions). Arrows indicate the position of heavy and light chain
bands.
B. Immunoblot analysis using Mab HP130
Purified 65 kDa precursor Heparanase (50 ng; lane 1) and purified 50
kDa Heparanase subunit (50 ng; lane 2) were loaded onto 4-12% SDSPAGE.
The proteins were transferred to PVDF membrane and
subjected to Western blot analysis using HP130. The 65 kDa precursor
and the 50 kDa subunits are clearly detected.
