General description
Protein A is a 42 kD, highly stable cell surface receptor isolated from Staphylococcus aureus which binds selectively and with high affinity to the Fc portion of IgG from various species[1][2].Protein A-gold is an electron dense, non-fading marker and can be used as a probe in electron microscopy (TEM and SEM), light microscopy and blotting. Protein A - 20 nm colloidal gold reacts specifically with IgG of human.
Application
Protein A-Gold can be used in dot blot. It can also be used to detect immunoglobulins.
Other Notes
Protein A, extracellular (P 6031), adsorbed to colloidal gold.
Physical form
Suspension in 0.02 M Tris-buffered saline, containing 1% bovine serum albumin, 30% glycerol, and 15 mM sodium azide.
