Endotoxin

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

Activity

Measured in a cell proliferation assay using MCF-7 cells.The ED50 for this effect is typically 2-10 ng/mL.

Protein Construction

A DNA sequence encoding the N-terminal fragment (Ser 2-Lys 246) of human NRG1 isoform beta1 (Q02297-6) was expressed.

Accession#

Q02297-6

Expressed Host

HEK293 Cells

Species

Human

Predicted N Terminal

Ser 2

Molecule Mass

The recombinant human NRG1 comprises 245 amino acids and has a predicted molecular mass of 26.8 kDa. As a result of glycosylation, it migrates as an approximately 47.7 kDa band in SDS-PAGE under reducing conditions.

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.
