Integrin alpha 8 beta 1 Protein, Human (HEK293, Flag, His)

Integrin α-8/β-1 coordinates the recruitment of mesenchymal cells during renal organogenesis and recognizes RGD sequences in ligands such as TNC, FN1, SPP1, TGFB1, TGFB3, and VTN. It plays a role in multiple cellular interactions critical for organogenesis, including NPNT as a functional ligand in nephrogenesis. Integrin alpha 8 beta 1 Protein, Human (HEK293, Flag, His) is a recombinant protein dimer complex containing human-derived Integrin alpha 8 beta 1 protein, expressed by HEK293 , with C-10*His, C-Flag labeled tag. Integrin alpha 8 beta 1 Protein, Human (HEK293, Flag, His), has molecular weight of ~85-140 kDa.

The Integrin alpha-8/beta-1 protein plays a crucial role in organogenesis, particularly in the development of the kidney and potentially other organs, by orchestrating the recruitment of mesenchymal cells into epithelial structures. Recognizing the R-G-D sequence within a broad spectrum of ligands, including TNC, FN1, SPP1, TGFB1, TGFB3, and VTN, Integrin alpha-8/beta-1 is implicated in diverse cellular interactions critical for organ formation. In kidney genesis, NPNT is identified as its likely functional ligand. Acting as a neuronal receptor for TNC, it regulates cell-cell interactions and modulates the neurite outgrowth of sensory and motor neurons. Structurally, Integrin alpha-8/beta-1 forms a heterodimer, with the alpha subunit comprising a heavy and a light chain linked by a disulfide bond. Specifically, the alpha-8 subunit associates with the beta-1 subunit, underscoring its integral role in mediating cell-matrix and cell-cell interactions during organ development and neural processes.

Measured by its binding ability in a functional ELISA. Immobilized Human Fibronectin, at 5 μg/mL (100 μL/well) can bind Biotinylated Human Integrin alpha 8 beta 1 protein. The ED₅₀ for this effect is 428.7 ng/mL

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
