XpressAffinity Protein G provides a fast and convenient method for affinity based isolation of proteins using the magnetic method. Protein G is immobilized on magnetic nanoparticles (size range: 10-20nm) using a patented technology. The blocking step during preparation of the resin minimizes non- specific binding of other contaminating proteins present in the biological samples and also minimizes leaching of the immobilized protein from the matrix.
The product is provided as 10mg magnetic particles in 1 ml of phosphate buffer (pH 8) containing 0.05% Tween-20 and 0.05% sodium azide. Recommended storage temperature is 4ºC. Do not freeze the product.
