Mouse Fc gamma RI/CD64 Protein

产品信息(Product Info)

Recombinant Mouse Fc gamma RI/CD64 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Glu25-Pro297.[Accession | P26151-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 31.5 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result.


Less than 1EU per ug by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.


Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Mouse Fc gamma RI on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


The purity of Mouse Fc gamma RI is greater than 95% as determined by SEC-HPLC.

SPR Data

Trastuzumab captured on CM5 Chip via Protein A can bind Mouse Fc gamma RI, His Tag with an affinity constant of 87.0 nM as determined in SPR assay (Biacore T200).


The Fc gamma Rs have been divided into three classes based on close relationships in their extracellular domains; these groups are designated Fc gamma  RI (also known as CD64), Fc gamma  RII (CD32), and Fc gamma  RIII (CD16). Each group may be encoded by multiple genes and exist in different isoforms depending on species and cell type. The CD64 proteins are high affinity receptors (~10e-8-10e-9 M) capable of binding monomeric IgG, whereas the CD16 and CD32 proteins bind IgG with lower affinities (~10e-6-10e-7 M) only recognizing IgG aggregates surrounding multivalent antigens.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lypholized powder.
