DLL4 Protein, Mouse, Recombinant (His Tag): 产品信息
纯度
> 96 % 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
1. Measured by its binding ability in a functional ELISA. Immobilized mouse DLL4-his (Cat:50640-M08H) at 10 μg/mL (100 μL/well) can bind biotinylated mouse NOTCH1-his. The EC50 of biotinylated mouse NOTCH1-his is 30 ng/mL.
2. Measured by the ability of the immobilized protein to enhance BMP2-induced alkaline phosphatase activity in C3H10T1/2 mouse embryonic fibroblast cells. The ED50 for this effect is typically 1-5 μg/mL in the presence of 500 ng/mL recombinant human BMP2.
蛋白构建
A DNA sequence encoding the extracellular domain of mouse DLL4 (NP_062327.2) (Met 1-Pro 525) was expressed, with a C-terminal polyhistidine tag.
分子量
The secreted recombinant mouse DLL4 comprises 509 amino acids and has a calculated molecular mass of 55.7 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 68 kDa band in SDS-PAGE under reducing conditions.
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.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
