PANSORBIN^® Cells, Standardized

Heat-killed, formalin-fixed Staphylococcus aureus cells (Cowan I strain) that bear a high cell-surface density of protein A and have been pickled by the method of Kessler. Useful as a solid-phase IgG-binding reagent due to the high-affinity interaction of protein A with the Fc domain of IgG. PANSORBIN cells work best when the antibody is human (IgG₁, IgG₂, IgG₄), rabbit IgG (all isotypes), or mouse (IgG_2a, IgG_2b, IgG₃).

PANSORBIN Cells are heat-killed, formalin fixed Staphylococcus aureus cells that have a coat of protein A and have been pickled by the method of Kessler. Useful for mitogenic stimulation of B lymphocytes and for immunoprecipitation.

Most common applications include immunoprecipitation and mitogenic stimulation of B lymphocytes.

Supplied as a ≥10% (w/v) Staphylococcus aureus cell suspension in PBS, 0.1% sodium azide, pH 7.2.
