The Mini Protein G spin column is the ideal tool for screening antibody expression and for small-scale purification of antibodies for solution-state immuno-assay, immuno-histochemical and immuno-fluorescence studies, Western blotting and immuno-precipitation studies. Antibodies are purified using a powerful, patented affinity spin column using a microfuge common to all biochemistry and immunology laboratories. The binding capacity per use (3x) is typically 1 mg human IgG. The resin bed volume is 0.23 ml, the maximum volume is 0.65 ml. Contains 16 Mini Protein G Spin Columns and enough ready-to-use buffers for 48 mini preps.
