HumanAngiopoietin-4/ANGPT4Protein Product Information
A DNA sequence encoding the human ANGPT4 (NP_068769.2) (Met282-Ile503) was expressed, with an N-terminal polyhistidine tag.
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.
HumanAngiopoietin-4/ANGPT4Protein QC Testing
> 80 % as determined by SDS-PAGE
< 1.0 EU per μg of the protein as determined by the LAL method
Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:
The recombinant human ANGPT4 comprises 242 amino acids and has a predicted molecular mass of 27.6 kDa. The apparent molecular mass of the protein is approximately 38 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol 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.
HumanAngiopoietin-4/ANGPT4Protein Usage Guide
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.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
