Name :
Recombinant Human CD32B/Fcgr2b Protein (ECD, His Tag), HPLC-verified
Biological Activity :
Background :
Biological Activity :
Measured by its ability to bind biotinylated human IgG2 (Cat: 13504-HNAH) in functional ELISA.
Expression Host :
Human
Source :
HEK293 Cells
Tag :
Protein Accession No. :
NP_001002274.1
NCBI Gene ID :
Synonyms :
Synonyms :
Fc fragment of IgG, low affinity IIb, receptor (CD32)
Amino Acid Sequence :
Molecular Weight :
The recombinant mature human CD32b consists of 183 amino acids after proteolytic removal of the signal peptide and predicts a molecular mass of 20.8 kDa. By SDS-PAGE under reducing conditions, it migrates as an approximately 25-30 kDa protein due to glycosylation.
Purity :
≥ 95 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.
State of Matter :
Product Concentration :
Storage and Stability :
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.
Endotoxin Level :
< 1.0 EU per μg of the protein as determined by the LAL method
Protein Construction :
A DNA sequence encoding the extracellular domain (Ala 46-Pro 217) of mature human CD32b (NP_001002274.1) protein was expressed with a N-terminal signal peptide and a C-terminal polyhistidine tag.
Buffer Solution :
Lyophilized from sterile PBS, pH 7.4.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 hardcopy of datasheet.
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.
Redissolution :
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
