It is electron dense marker and has a wide application in electron microscopy, light microscopy, blotting procedures. 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. Concentration: approximately 0.01% A520 =approximately 0.75.

Quantum dots (QDs) are inorganic semiconductor nanocrystals that have tunable fluorescence properties. QDs have high quantum yields, broad absorption spectra, narrow size-tunable emissions, and are resistant to photobleaching as well as to chemical degradation. Quantum dots (QDs) have the potential to become a new class of fluorescent probes for many biological and biomedical applications. Our quantum dots are water soluble and they can be applied directly for conjugation of biomolecules
