Recombinant EGF-like domain (Thr 176-Lys 246) of human NRG1 isoform beta1 (Q02297-6) was fused with the Fc region of human IgG1 at the N-terminus.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured by its binding ability in a functional ELISA.2. Immobilized Rhesus ErbB3 at 2 μg/mL (100 μl/well) can bind human NRG1 (isoform Beta1), The EC50 of human NRG1 (isoform Beta1) is 0.58 μg/mL.3. Immobilized human ErbB3 at 2 μg/mL (100 μl/well) ca
The recombinant human NRG1(aa176-246)/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 331 amino acids and has a calculated molecular mass of 36.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh NRG1/Fc monomer is approximately 38 kDa.
< 1.0 EU per μg of the protein as determined by the LAL method.
>86 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
