人EGF蛋白产品状态&运输说明：
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.


质控检测
纯度：
> 92 % as determined by SDS-PAGE.
生物活性：
Measured in a cell proliferation assay using Balb/C 3T3 mouse embryonic fibroblasts. (Rubin, J.S. et al. 1991, Proc. Natl. Acad. Sci. USA 88:415.)
The ED50 for this effect is typically 20-100 pg/mL.

预测N端：
Met 1
分子量：
The recombinant human EGF consisting of 54 amino acids and has a calculated molecular mass of 6.3 kDa as estimated in SDS-PAGE under reducing conditions.

缓冲液：
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.


使用指导
储存方法：
Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

复溶条件：
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.人EGF蛋白
