Electron Microscopy Sciences Aurion Gold Sol, 15 nm 100 ML
To prepare a high quality (immuno)gold conjugate it is important to have particles with uniform size and highly adsorptive surfaces. Prepared according to unique production protocols, Aurion Sols have the same narrow size distribution and adsorption properties as employed in the Conventional Immunogold Reagents.
The gold particles with a diameter suited for direct electron microscopic visualization. Aurion offers a range of Conventional Immunogold Reagents which cover the majority of approaches in transmission and scanning electron microscopy.
Aurion Gold Sols (solutions of high quality unconjugated gold particles) provide opportunities for users to prepare conjugates with primary antibodies, ligands and other binding agents with the same particle characteristics as in the Conventional Immunogold Reagents.

Bioworld Bioalginate Beads, Macro (BAB), 100 mL
Bioalginate Alginate, commonly called sodium alginate, is a linear polysaccharide. The copolymer consists of two uronic acids: D-mannuronic acid (M) and L-guluronic acid (G ). Sodium alginate as well as other alkali metal alginates are water soluble, whereas the salts of polyvalent cations, e.g., calcium, nickel, copper, cobalt are water insoluble, with the exception of magnesium. Polyvalent cations bind to the polymer whenever there are two neighboring guluronic acid residues. Thus, polyvalent cations are responsible for the cross-linking of both different polymer molecules and different parts of the same polymer chain. The process of gelation, i.e. the exchange of polyvalent ions for sodium ions is carried out under relatively mild conditions. Technical specificationsMicrobeads: 150-250 µm.
