Human CD96 Protein (His Tag)

TACTILE

Catalog Number P11202-H08H
Organism Species Human
Host Human Cells
Synonyms TACTILE
Molecular Weight The recombinant human CD96 consists of 493 amino acids and predictes a molecular mass of 55 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh CD96 is approximately 120-130 kDa due to high glycosylation.
predicted N Val 22
SDS-PAGE
Purity > 90 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the human CD96 isoform 2 (P40200-2) extracellular domain (Met 1-Met 503) was expressed, with a polyhistidine tag at the C-terminus.
Bio-activity 1. Measured by its ability to bind recombinant mouse PVR in a functional ELISA.
2. Measured by its ability to bind recombinant Human CD155 in a functional ELISA.
Research Area Immunology |Innate Immunity |Monocytes/Macrophages |Co-stimulatory Molecules
Formulation Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. The CD155 ligand CD96 is a member of the Ig superfamily. It's a immunoglobulin-like protein tentatively allocated to the repertoire of human NK receptors. NK cells recognize poliovirus receptor (PVR), a nectins and nectin-like protein family member serve to mediate cell-cell adhesion, cell migration, with the presence of an additional receptor, CD96. CD96 promotes NK cell adhesion to target cells expressing PVR, stimulates cytotoxicity of activated NK cells, and mediates acquisition of PVR from target cells. The effect the cells with mutated CD96 protein lost adhesion and growth activities indicates that CD96 mutations may cause a form of the C syndrome by interfering with cell adhesion and growth.
