Recombinant Mouse PVR (C-mIgG2

产品说明(Description)

Recombinant Mouse Poliovirus Receptor is produced by our Mammalian expression system and the target gene encoding Asp29-Leu348 is expressed with a mIgG2AFc tag at the C-terminus.

Accession #: NP_081790

Known as: Poliovirus receptor; CD155 antigen; Nectin-like protein 5; Nectin-2; Tage4 receptor; Pvr; PVR; Necl5; CD155

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制(Quality Control)

 

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.

Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景(Background)

Mouse poliovirus receptor (PVR, CD155) is a type I transmembrane (TM) glycoprotein that is a member of the nectin-related family of adhesion proteins within the immunoglobulin superfamily. It binds other molecules including vitronectin, Nectin3, DNAM1, CD96, and TIGIT, but does not bind homotypically. CD155 includes a 28 aa signal sequence, a 318 aa extracellular domain (ECD) with one N-terminal V-type and two C2-type Ig-like domains, a 24 aa TM segment and a 38 aa cytoplasmic tail. Epithelial, endothelial, and many immune cells show low CD155 expression. It is up-regulated on endothelia by IFNγ, and is highly expressed on immature thymocytes, lymph node dendritic cells, and tumor cells of epithelial and neuronal origin. On migrating cells, it is concentrated at the leading edge, where it binds basement membrane vitronectin, recruits Nectin-3-expressing cells, and cooperates with PDGF and integrin αvβ3 to promote cell migration. Binding of monocyte DNAM-1 to endothelial cell CD155 promotes transendothelial migration. Enhanced CD155 expression in tumor cells contributes to loss of contact inhibition and increased migration, but also allows tumor cell recognition and killing by DNAM-1or CD96 expressing NK cells.
