Human Siglec-7 & J chain Heterohexamer Protein, Human IgM Fc Tag & His Tag, produced by co-expression of Siglec-7 and J chain, has a calculated MW of 75.7 kDa (Siglec-7) and 17.5 kDa (J chain). Subunit Siglec-7 is fused with a Human IgM Fc tag at the C-terminus which self-assembles to homopentamer, and subunit Joining chain (J chain) is fused with a polyhistidine tag at the C-terminus.
