GAHM40 is part of the anti-human gold conjugate family, consisting of Goat anti Human IgM conjugated to 40nm BBI gold nanoparticles. The antibody reacts with Fc5μ portion of the human IgM heavy chain but not with human IgG, IgA or the light chains of human immunoglobulins. Suitable for use in lateral flow devices, the goat anti human IgM antibody is passively coupled to citrate capped gold nanoparticles and blocked with bovine serum albumin (BSA). The conjugate is suspended in a low molarity buffer 2mM disodium tetraborate buffer, pH9.0, containing 0.095% Sodium Azide as preservative. This buffer will maintain the activity of the antibody attached to the surface of the gold colloid, without causing particle aggregation, and can easily be substituted for a customers buffer of choice for their assay. This product can be purchased online in 5ml or 100mL volumes at OD10. For larger volumes, please discuss your requirements with our sales team. Customised concentrations of conjugates to an OD other than OD10 are also available by request.
