DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human CPNE1 Protein Product Information
Synonym:CPNE1, CPN1
Protein Construction:A DNA sequence encoding the human CPNE1 (Q99829) (Met1-Ala537) was fused with the SUMO tag at the N-terminus.
Expressed Host:Baculovirus-Insect Cells
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.
Human CPNE1 Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Met
Molecule Mass:The secreted recombinant human CPNE1 consists of 656 amino acids and predicts a molecular mass of 72.7 KDa. The apparent molecular mass of the protein is approximately 73 KDa in SDS-PAGE under reducing conditions due to glycosylation.
Formulation:Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.0, 10% gly
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.

Copine I / CPN1 Background

Copine I, also known as CPN1, is a member of the copine family. Copine I is a calcium-dependent membrane-binding protein which has a wide tissue distribution. Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. Copine I contains two N-terminal type II C2 domains and an integrin A domain-like sequence in the C-terminus, while it does not contain a predicted signal sequence or transmembrane domains. Copine I may function in membrane trafficking.
