NanoVan

NANOVAN™ is a negative stain for electron microscopy specially tailored for use with NANOGOLD™ antibody conjugates, not available elsewhere. It is based on vanadium, which has a lower atomic number (23) than other elements commonly used as negative stain reagents such as uranium (92), tungsten (74) or lead (82). NANOVAN™ is recommended for visualization of all samples labeled with NANOGOLD™, and may be used in other applications where a relatively light stain is required.1 It produces a light, uniform negative stain. NANOVAN™ is stable, non-volatile in the beam and will not denature protein samples.

NANOVAN™ is supplied ready-to-use, as a 2 % solution in water at pH 8.0. It is recommended that this product not be used at pH values lower than 7 since precipitation may occur.

NANOVAN™ should be refrigerated upon receipt, and stored at 2 - 8oC.
