General description

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.

Target description

Chondroitin sulfate proteoglycan 4 (UniProt: Q00657; also known as Chondroitin sulfate proteoglycan NG2, HSN tumor-specific antigen) is encoded by the Cspg4 (also known as Ng2) gene (Gene ID: 81651) in rat. Chondroitin sulfate proteoglycan NG2 is a single-pass type I membrane protein that plays a role in cell proliferation and migration and stimulates endothelial cells motility during microvascular morphogenesis. It is present in neural cells and in extraneural tissues, especially in the developing mesenchyme. Its level of expression is highest on immature, proliferating cells and decreases when these cells begin to differentiate. It is found on the surfaces of an unusual class of glial cells within the developing and mature central nervous system that have the properties of oligodendrocyte precursor cells. It is a major chondroitin sulfate proteoglycan that is produced after spinal cord injury and is expressed by macrophages and oligodendrocyte progenitors. It is also reported to inhibit neurite outgrowth and growth cone collapse during axon regeneration. NG2 chondroitin sulfate proteoglycan is synthesized with a signal peptide (aa 1-29), which is subsequently cleaved off in the mature form. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
