Ziege IgG anti-Human IgM (µ)-Gold 4nm, MinX keine

Based on immunoelectrophoresis and/or ELISA, the antibody reacts with the Fc5µ portion of the human IgM heavy chain but not with human IgG, IgA, or the light chains of human immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody may cross-react with IgM from other species.

Since signal intensity is relatively independent of particle size when silver enhancement is used, Jackson ImmunoResaerch offers 4 nm particles because this size may penetrate tissues better than larger particles.

The 4 nm size may be used for electron microscopy in studies that require smaller particles since they are relatively uniform in size (coefficient of variation less than or equal to 15%), though small aggregates are not removed from this grade. Therefore, the 4 nm particles should only be used for electron microscopy with the understanding that the presence of small aggregates may give misleading results.

A detailed protocol for silver enhancement is provided with all orders for LM Grade products. All reagents involved in the light-insensitive silver enhancement reaction can be prepared easily in the laboratory. However, those who wish to use commercially available silver enhancement kits can continue to do so. All LM Grade colloidal gold-protein complexes are freeze-dried in buffer with stabilizers and a preservative. After reconstitution, they may be frozen in aliquots for extended storage
