Recombinant Human ITGAV(Phe 31 - Val 992)/ITGB3 (Gly 27 - Asp 718) Heterodimer Protein, Subunit ITGAV is fused with polyhistidine tag at the C-terminus and followed by a acidic tail and subunit ITGB3 contains no tag but a basic tail at the C-terminus was expressed in HEK293.
Integrin alpha-V/beta-3 (ITGAV:ITGB3) is a receptor for cytotactin, fibronectin, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin, vitronectin and von Willebrand factor. Integrins alpha-IIb/beta-3 and alpha-V/beta-3 recognize the sequence R-G-D in a wide array of ligands. Also, Integrin alpha-V/beta-3 acts as a receptor for herpes virus 8/HHV-8, coxsackievirus A9, Hantaan virus, cytomegalovirus/HHV-5, human metapneumovirus, human parechovirus 1 and west nile virus. Furthermore, in case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions.
Predicted N Terminal:
The predicted N-terminus is Phe 31 (ITGAV) & Gly 27 (ITGB3)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.
Has a calculated MW of 113 kDa (ITGAV) and 81.8 kDa (ITGB3). The reducing (R) protein migrates as 145 kDa (ITGAV) and 100-116 kDa (ITGB3) respectively due to glycosylation.
ITGAV(Phe 31 - Val 992)/ITGB3 (Gly 27 - Asp 718)
Less than 1.0 EU per μg of the Human ITGAV & ITGB3 Heterodimer Protein by the LAL method.
>95% as determined by SDS-PAGE.
Avoid repeated freeze-thaw cycles.No activity loss was observed after storage at:In lyophilized state for 1 year (4 centigrade); After reconstitution under sterile conditions for 3 months (-70 centigrade).
