Recombinant Human Endothelial Cell-Specific Molecule 1/ESM-1 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (W20-R184) of Human ESM1 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.
ESM-1, short from Endothelial cell-specific molecule 1, is expressed in lung, on the vascular capillary network within alveolar walls, and also at lower level in kidney. It is a secretory protein, and can be inducted by TNF and IL1B/interleukin-1beta, but not IL4/interleukin-4. This protein plays great roles in angiogenesis, sprouting, and may have potent implications in lung endothelial cell-leukocyte interactions.
