Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method

Activity

1. Immobilized Human ERBB3 His at 2 μg/ml (100 μl/well) can bind Human NRG1 Fc, the EC50 of Human NRG1 Fc is 8-40 ng/mL. 2. Immobilized Rhesus ERBB3 His at 2 μg/ml (100 μl/well) can bind Human NRG1 Fc, the EC50 of Human NRG1 Fc is 20-80 ng/mL.

Protein Construction

A DNA sequence encoding the N-terminal fragment (Ser 2-Lys 246) of human NRG1 isoform beta1 (Q02297-6) was fused with the Fc region of human IgG1 at the N-terminus.

Molecule Mass

The recombinant human NRG1（aa2-246）/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 505 amino acids and has a calculated molecular mass of 55.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of the protein is approximately 75 kDa due to glycosylation.

Formulation

Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Shipping

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.

Stability & Storage

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.

Reconstitution

A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
