  • InVivoMAb anti-mouse CD71 (TfR1)

    Description

    The OX-26 monoclonal antibody reacts with rat CD71 also known as transferrin receptor protein 1 (TfR1). The antibody is reported to cross-react with mouse CD71 as well. CD71 is a 170-180 kDa type II homodimeric transmembrane glycoprotein which is expressed on the surface of proliferating cells, reticulocytes, and erythroid precursors. CD71 plays a role in the control of cellular proliferation and is required for iron import from transferrin into cells by endocytosis. CD71 is expressed on malignant cells at high levels and its expression correlates with cancer progression. This high expression on malignant cells along with CD71’s ability to internalize and the necessity of iron for cancer cell proliferation makes the transferrin receptor an attractive target to exploit for the delivery of drugs into malignant cells. Upon binding to an extracellular domain of CD71, OX-26 is transferred into the blood-brain barrier (BBB) via the endogenous transferrin transport system. Under this mechanism, the OX-26 antibody is often used to transport conjugated drugs across the BBB in experimental rat models.

  • InVivoMAb anti-mouse CD71 (TfR1)

    Description

    The 8D3 monoclonal antibody reacts with mouse CD71 also known as transferrin receptor protein 1 (TfR1). CD71 is a 170-180 kDa type II homodimeric transmembrane glycoprotein which is expressed on the surface of proliferating cells, reticulocytes, and erythroid precursors. CD71 plays a role in the control of cellular proliferation and is required for iron import from transferrin into cells by endocytosis. CD71 is expressed on malignant cells at high levels and its expression correlates with cancer progression. This high expression on malignant cells along with CD71’s ability to internalize, and the necessity of iron for cancer cell proliferation make the transferrin receptor an attractive target to exploit for the delivery of drugs into malignant cells. The 8D3 antibody has been shown to deplete CD71+ cells in vivo.

  • InVivoMAb anti-mouse CD28

    Description

    The D665 monoclonal antibody reacts with mouse CD28, a 45 kDa costimulatory receptor and a member of the Ig superfamily. CD28 is expressed by thymocytes, most peripheral T cells, and NK cells. CD28 is a receptor for CD80 (B7-1) and CD86 (B7-2). Signaling through CD28 induces IL-2 and IL-2 receptor expression and T cell proliferation. The D665 antibody is a CD28 superagonist and is most commonly used to induce the expansion of Treg cells in vivo in various mouse models of disease.

  • InVivoMAb anti-mouse IL-23 (p19)

    Description

    The G23-8 monoclonal antibody reacts with the p19 subunit of mouse IL-23. IL-23 is a heterodimeric cytokine composed of two disulfide-linked subunits, a p19 subunit that is unique to IL-23, and a p40 subunit that is shared with IL-12. IL-23 is secreted by activated dendritic cells and macrophages. IL-23 has been shown to enhance IFNγ production by memory T cells. Additionally, mouse IL-23 induces the proliferation of memory T cells (but not naive T cells), whereas IL-12 has no effect on memory cells. Mouse IL-23 (but not IL-12) can also activate mouse memory T cells to produce the potent proinflammatory cytokine IL-17. IL-23 has been shown to be upregulated in certain autoimmune diseases and promote immunity in response to some viral and mycobacterial infections. The G23-8 antibody can specifically neutralize IL-23 bioactivity with no effect on IL-12 p70 bioactivity.
