Nonconjugated Colloidal gold

• Cat.No.: Colloidal gold-010
• Product Overview: Recently conjugates of antibodies with colloidal gold were applied for quantitative photometric determination of appropriate antigens. Colloidal gold conjugated with antibodies are applied widely also for qualitative determination of appropriate antigens in strips. Recently new ways for application of colloidal gold also were presented. Modified colloidal gold is able to bind DNA and to detect hybridization. Colloidal gold for various purposes is prepared with various sizes. We can supply the following sizes 3-5 nm, 13-15 nm, and 20 nm, 40 nm 50 nm that can be used in various research areas.
