IL-4I1, IL4I1, IL4-I1, IL4I-1
IL4I1 is a secreted L-amino acid oxidase protein that mainly catabolizes L-phenylalanine. IL4I1 eexpression is induced by the IL4 in B cells.IL4I1 is expressed in dendritic cells & macrophagesIL4I1 takes part in the immune system since it is expressed in tumor-associated macrophages and suppresses T-cell responses. IL4I1 plays a role in the binding of flavin adenine dinucleotide cofactor.
IL4R produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (26-232 a.a.) and fused to an 8 aa His Tag at C-terminus containing a total of 215 amino acids and having a molecular mass of 24.7kDa.
IL4R shows multiple bands between 28-40kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
IL4I1 protein solution (0.25mg/ml) contains 25mM MES pH-5.5, 40% glycerol and 100mM NaCl.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90% as determined by SDS-PAGE.
> 300 pmol/min/ug, defined as the amount of enzyme that oxidize 3-phenylpyruvate pH-7 at 25C.
