Recombinant Human Integrin alpha-5/ITGA5 produced by transfected human cells is a secreted protein with sequence (Phe42-Tyr995) of Human ITGA5 fused with a polyhistidine tag at the C-terminus.
纯度
> 95 % as determined by reducing SDS-PAGE.
过滤
0.2 μm filtered
内毒素水平
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
缓冲液
Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.
注意事项
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
储存条件
4 °C/-20 °C/-80 °C
储存方法
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.
Integrin alpha-5 belongs to the Integrin alpha chain family and contains 7 FG-GAP repeats. Integrin alpha-5 joins with Integrin-beta1 to form a fibronectin and laminin receptor which recognizes the sequence R-G-D in its ligands. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions. It is expressed on fibroblasts, endothelial cells, peripheral T cells and platelets. Integrin alpha-5 undergoes post-translational cleavage in the extracellular domain to yield disulfide-linked light and heavy chains. In addition to adhesion, ITGA5 participates in cell-surface mediated signalling.
