ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Immunogen

KLH-conjugated liner peptide corresponding to 24 amino acids from the C-terminal half of human Glypican-1, isoform 1.

Application

Anti-Glypican-1, clone 1J4 ZooMAb, Cat. No. ZRB1374, a recombinant Rabbit monoclonal antibody that targets Glypican-1 and is tested in Affinity Binding, Immunofluorescence, and Immunohistochemistry, and Western Blotting.
Western Blotting Analysis: A 1:10,000 dilution from a representative lot detected Glypican-1 in MDA-MB-231 cell lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected Glypican-1 in human pancreatic cancer tissue sections.

Immunofluorescence Analysis: A 1:1,000 dilution from a representative lot detected Glypican-1 in human pancreatic cancer tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound Glypican-1 peptide with a KD of 4.3 x 10-7 in an affinity binding assay.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Glypican-1 (UniProt: P35052; also known as GPC1) is encoded y the GPC1 gene (Gene ID: 2817) in human. Glypican-1 is a cell-surface glycoprotein that attaches to the plasma membrane via via glycosylphosphatidylinositol (GPI) anchors. It is synthesized with a signal peptide (aa 1-23) and a propeptide (aa 531-538) that are subsequently cleaved off to produce mature protein. Glypican-1 undergoes N- and O-glycosylations. N-glycosylation is mainly of the complex type containing sialic acid whereas O-glycosylation is with heparan sulfate Heparan sulfate chains are cleaved either by heparinase or are degraded by deaminative process that uses nitric oxide released from the S-nitrosylated cysteines. Glypican-1 is shown to be essential for proper skeletal muscle differentiation. It can act as a catalyst in increasing the rate of conversion of prion protein PRPN(C) to PRNP(Sc) via associating with both forms of PRPN, targeting them to lipid rafts and facilitating their interaction. It can also sequester FGF2 in lipid rafts and blocks its binding to FGF receptors. Glypican-1 is specifically enriched on cancer-cell-derived exosomes and levels of glypican-1 positive exosomes correlate with tumor burden and the survival of pre- and post-surgical patients. It is also over-expressed in human gliomas and in pancreatic cancer cells. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
