Function

Integral component of basement membranes. Component of the glomerular basement membrane (GBM), responsible for the fixed negative electrostatic membrane charge, and which provides a barrier which is both size- and charge-selective. It serves as an attachment substrate for cells. Plays essential roles in vascularization. Critical for normal heart development and for regulating the vascular response to injury. Also required for avascular cartilage development. Endorepellin. Anti-angiogenic and anti-tumor peptide that inhibits endothelial cell migration, collagen-induced endothelial tube morphogenesis and blood vessel growth in the chorioallantoic membrane. Blocks endothelial cell adhesion to fibronectin and type I collagen. Anti-tumor agent in neovascularization. Interaction with its ligand, integrin alpha2/beta1, is required for the anti-angiogenic properties. Evokes a reduction in phosphorylation of receptor tyrosine kinases via alpha2/beta1 integrin-mediated activation of the tyrosine phosphatase, PTPN6. LG3 peptide. Has anti-angiogenic properties that require binding of calcium ions for full activity.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody in your assay.

Activity summary

Heparan Sulfate Proteoglycan 2 also known as Perlecan is a large multidomain proteoglycan with a mass of over 500 kDa. It contains heparan sulfate chains that contribute to its role in the extracellular matrix. Perlecan is expressed in various tissues including cartilage basement membranes and vascular tissues. It interacts with other matrix proteins providing structural integrity and influencing cell behavior.

Biological function summary

Perlecan plays a critical role in cell adhesion proliferation and growth factor signaling. It is an important component of basement membranes and forms a structural complex with other matrix proteins. Its interaction with heparan sulfate chains enables binding with various ligands such as growth factors and cytokines optimizing their availability and functionality at the cell surface. This interaction is essential in tissue maintenance and repair processes.

Pathways

Perlecan participates in the regulation of the Wnt and Hedgehog signaling pathways. These pathways influence key developmental processes and dictate cellular differentiation and migration. Perlecan and its heparan sulfate chains modulate protein interactions within these pathways notably affecting proteins such as Dsh and Ctnnb1 which are essential in signal transduction.

Associated diseases and disorders

Perlecan involvement has been linked with tumorigenesis and cardiovascular diseases. Aberrations in its structure or expression can alter cellular microenvironments impacting key processes like angiogenesis and metastasis. Furthermore its interaction with growth factors can facilitate the progression of diseases like cancer highlighting its connection with proteins such as VEGF and TGF-beta which play major roles in disease modulation.
