纯度
> 95 % as determined by Tris-Bis PAGE,> 95 % as determined by HPLC
过滤
0.22 μm filtered
内毒素水平
Less than 1EU per μg by the LAL method.
Biological Activity Comment
The affinity constant of 0.96 μM as determined in SPR assay (Biacore T200). See testing image for detail.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/mL is recommended. Dissolve the lyophilized protein in distilled water.
缓冲液
Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.
储存条件
-20 °C,-80 °C
储存方法
-20 to -80°C for 12 months as supplied from date of receipt., -80°C for 3-6 months after reconstitution., 2-8°C for 2-7 days after reconstitution., Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Alkaline phosphatase can be considered "our favorite enzyme" for reasons apparent to those who diagnose and treat metabolic bone diseases or who study skeletal biology. Few might know, however, that alkaline phosphatase likely represents the most frequently assayed enzyme in all of medicine. Elevated activity in the circulation is universally recognized as a marker for skeletal or hepatobiliary disease.
分子量
54.5 kDa. Due to glycosylation, the protein migrates to 63-73 kDa based on Tris-Bis PAGE result.
