Description

CD24 is a heavily glycosylated GPI-anchored protein implicated in tumor proliferation, metastasis, and immune evasion, making it a high-value target in cancer immunology research. This recombinant human CD24 construct spans the full mature protein (aa 27–59), is expressed in mammalian cells to preserve native-like glycosylation, and is presented on a nanoparticle scaffold bearing an N-terminal 6×His tag. Functional ELISA confirms robust binding activity, with immobilized CD24 at 2 μg/ml engaging an anti-CD24 recombinant monoclonal antibody at an EC50 of 5.409–8.219 ng/ml, supporting direct use as a positive control in antibody screening, epitope binning, and receptor-ligand binding assays. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for functional cell-based assays investigating CD24-mediated signaling or for evaluating anti-CD24 therapeutic antibody candidates in preclinical binding studies.

Target Background

Function

May have a pivotal role in cell differentiation of different cell types. Signaling could be triggered by the binding of a lectin-like ligand to the CD24 carbohydrates, and transduced by the release of second messengers derived from the GPI-anchor. Modulates B-cell activation responses. Promotes AG-dependent proliferation of B-cells, and prevents their terminal differentiation into antibody-forming cells. In association with SIGLEC10 may be involved in the selective suppression of the immune response to danger-associated molecular patterns (DAMPs) such as HMGB1, HSP70 and HSP90. Plays a role in the control of autoimmunity.
