Human CD24 Protein, Fc Tag

分子别名(Synonym)

CD24,CD24A

表达区间及表达系统(Source)

Human CD24, Fc Tag (CD4-H5254) is expressed from human 293 cells (HEK293). It contains AA Ser 27 - Gly 59 (Accession # P25063-1).

Predicted N-terminus: Ser 27

蛋白结构(Molecular Characterization)

Online(Ser 27 - Gly 59) P25063-1

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 29.6 kDa. The protein migrates as 40-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

存储(Storage)

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:

  1. -20°C to -70°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Human CD24, Fc Tag (Cat. No. CD4-H5254) SDS-PAGE gel

Human CD24, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human CD24, Fc Tag (Cat. No. CD4-H5254) at 10 μg/mL (100 μL/well) can bind Anti-CD24 MAb (SN3) with a linear range of 2-78 ng/mL (QC tested).

Protocol

背景(Background)

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.
