IGFBP2 Protein, Rhesus, Recombinant (His Tag): 产品信息
纯度
> 67 % as determined by SDS-PAGE
内毒素
< 1.0 EU per μg of the protein as determined by the LAL method
生物活性
Measured by its ability to inhibit the biological activity of IGFII on MCF7 human breast adenocarcinoma cells (Karey, K.P. et al. (1988) Cancer Research 48:4083.).
The ED50 for this effect is typically 0.02-0.1 μg/mL in the presence of 14 ng/mL human IGFII.
蛋白构建
A DNA sequence encoding the rhesus IGFBP2 (XP_001087071.1) (Met1-Gln324) was expressed, fused with a polyhistidine tag at the C-terminus.
分子量
The recombinant rhesus IGFBP2 comprises 300 amino acids and has a calculated molecular mass of 32.8 KDa.
缓冲液
Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
