CD32A Protein, Human, Recombinant (His Tag): Product Information

Purity
> 95 % as determined by SDS-PAGE
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Activity
Measured by its ability to bind Human IgG2-Fc (Native) (Cat:13504-HNAH) in a functional ELISA.
Protein Construction
A DNA sequence encoding the extracellular domain (Met 1-Ile 218) of human CD32a (P12318-1) was expressed with a C-terminal polyhistidine tag. It is identical to FCGR2A131H/R in the reference.
Accession#
Expressed Host
HEK293 Cells
Species
Human
Predicted N Terminal
Gln 34
Molecule Mass
The recombinant human CD32a consists of 196 amino acids after removal of the signal peptide and predicts a molecular mass of 22 KDa. It migrates as an approximately 30 KDa protein due to glycosylation by SDS-PAGE under reducing conditions.
Formulation
Lyophilized from sterile PBS, pH 7.5
Please 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 COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
