Descrizione

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.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.

Physical form

Suspension in 0.02 M Tris-buffered saline, containing 1% bovine serum albumin, 30% glycerol, and 15 mM sodium azide.

Other Notes

Protein A, extracellular (P 6031), adsorbed to colloidal gold.
