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

Measured by its ability to inhibit mIFNB1-mediated protection of L929 mouse fibroblast cells infected with vesicular stomatitis virus (VSV) to viral lysis.
The ED₅₀ for this effect is typically 0.2-1μg/mL.

蛋白构建

A DNA sequence encoding the extracellular domain of mouse IFNAR1 (NP_034638.2) extracellular domain (Met 1-Thr 429) was expressed, with a polyhistidine tag at the C-terminus.

NP No.

分子量

The recombinant mouse IFNAR1 consists of 414 amino acids and has a predicted molecular mass of 47 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm IFNAR1 is approximately 55-60 kDa due to glycosylation.

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.

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.
