Receptors that recognize the Fc portion of IgG are divided into three groups designated Fc gamma RI, RII, and RIII, also known respectively as CD64, CD32, and CD16. Fc gamma RI binds IgG with high affinity and functions during early immune responses. Fc gamma RII and RIII are low affinity receptors that recognize IgG as aggregates surrounding multivalent antigens during late immune responses. High affinity immunoglobulin gamma Fc receptor I is also known as FCGR1A, FCG1, FCGR1, CD64 and IGFR1, is a type of integral membrane glycoprotein that binds monomeric IgG-type antibodies with high affinity, which belongs to the immunoglobulin superfamily or FCGR1 family. FCGR1A / CD64 contains 3 Ig-like C2-type (immunoglobulin-like) domains. CD64 is constitutively found on only macrophages and monocytes, but treatment of polymorphonuclear leukocytes with cytokines like IFNγ and G-CSF can induce CD64 expression on these cells.

Recombinant Canine CD64, His Tag(FCA-C52H8) is expressed from human 293 cells (HEK293). It contains AA Gln 16 - Pro 288 (Accession # XP_025308990.1 ).Predicted N-terminus: Gln 16

Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 32.4 kDa. The protein migrates as 36-46 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Less than 1.0 EU per μg by the LAL method.

>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.

For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to -70°C for 12 months in lyophilized state;
-70°C for 12 months under sterile conditions after reconstitution.

Please refer to product data sheet.
