Protein Construction

A DNA sequence encoding the human CALR (P27797) (Met1-Ala413) was expressed with the Fc region of human IgG1 at the C-terminus.

Accession#

P27797

Expressed Host

HEK293 Cells

Species

Molecule Mass

The recombinant human CALR/Fc is a disulfide-linked homodimer. The reduced monomer comprises 637 amino acids and has a predicted molecular mass of 73 kDa. The apparent molecular mass of the protein is approximately 96 and 38 kDa 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. Please refer to the specific buffer information in the hard copy of CoA.

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.
