Protein Construction
A DNA sequence encoding the human SPINK2 (NP_066937.1) (Met1-Cys84) was expressed with the Fc region of human IgG1 at the C-terminus.
Expressed Host
HEK293 Cells
Predicted N Terminal
Gln 24
Molecule Mass
The recombinant human SPINK2 consists 299 amino acids and predicts a molecular mass of 33.6 kDa.
Formulation
Lyophilized from sterile PBS, pH 7.4.
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please
contact us for any concerns or special requirements.
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 -70℃
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 COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
