Recombinant Human Integrin alpha V beta 8 Heterodimer (C-6His) (C13X)

产品说明(Description)

Recombinant Human Integrin Alpha V & Beta 8 is produced by our Mammalian expression system and the target gene encoding Phe31-Val992&Glu43-Arg684 is expressed with a 6His tag at the C-terminus.

Accession #: P06756&P26012

Known as: Integrin alpha V beta 8; ITGAV&ITGB8; Integrin alpha V beta 8 Heterodimer; Integrin Alpha V & Beta 8   

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of 50 mM Tris-HCl, 100 mM NaCl, pH 8.0.

 

质量控制(Quality Control)

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

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) 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 100μg/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)

Integrin alpha V beta 8 is one of five alpha V integrins, is expressed in yolk sac, placenta, brain perivascular astrocytes, Schwann cells, renal glomerular mesangial cells and pulmonary epithelial cells. Unlike other alpha V integrins, ITGAVB8 does not appear to assume different activation states, and the cytoplasmic tail does not connect to the cytoskeleton. It binds ligands containing an RGD motif, including vitronectin, fibrin and the latency associated peptide (LAP) of the latent TGF-beta complex. High affinity binding of alpha V beta 8 to LAP allows proteolytic cleavage by MT1-MMP, which releases active TGF-beta. This mechanism differs from that of alpha V beta 6, the other alpha V integrin which can activate TGF-beta from latency through non-proteolytic mechanisms. Downstream effects of TGF-beta activation include control of cell growth and associated vascularization. Deletion of either alpha V or beta 8 reveals that alpha V beta 8 is required for vascular morphogenesis in the embryonic brain and yolk sac.
