hCG is part of the fertility Gold Conjugate family. Human Chorionic Gonadotrophin (hCG) is a hormone produced in pregnancy soon after conception. It is the standard marker for early pregnancy testing. The BBI conjugate (BA.HCG40) and matched pair capture (01041131C) are designed for use in human urine, not serum. The monoclonal capture antibody (01041131C) recognises the beta chain and beta core fragment of hCG. Its purity is >95% and doesn't cross recat with with alpha hCG, FSH or TSH. The conjugate is suspended in a low molarity buffer 2mM Borax pH9.0 containing 0.095% Sodium Azide as a preservative. All gold conjugate products are available at OD10 in volumes of 5, 50, 100 or 500mls unless stated otherwise. Customised concentrations of conjugates with an OD other than OD10, are available by request.
