FCGRT & B2M-1249M
Recombinant extracellular domain (Met 1-Ser 297) of human FCGRT (P55899) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; Recombinant human B2M (P61769) (Met 1-Met 119) constructed the plasmid 2. The two plasmids were co-ex
Predicted N Terminal:
Ala 24 & Ile 21
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
Measured by its ability to bind human IgG1 in functional ELISA.
The recombinant heterodimer of human FCGRT / B2M comprises 385 ( 285 + 100 ) amino acids and has a calculated molecular mass of 43.5 ( 31.8 + 11.7 ) kDa. The apparent molecular mass of rh FCGRT / B2M heterodimer is approximately 35 & 12 kDa respectively in SDS-PAGE under reducing conditions
< 1.0 EU per μg of the protein as determined by the LAL method.
>95 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
