Biotinylated Cynomolgus CD24, Fc Tag, primary amine labeling (CD4-C8254) is expressed from human 293 cells (HEK293). It contains AA Thr 27 - Lys 54 (Accession # I7GKK1-1).
Predicted N-terminus: Thr 27
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 29.3 kDa. The protein migrates as 45-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.
The biotin to protein ratio is 3-5 as determined by the HABA assay.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

CD24 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.
