Description

General description

Black-Gold II is an aurohalophosphate complex which stains specifically for myelin within the central nervous system. Black-Gold II staining provides high resolution, high contrast, a short histochemical processing time, and high reproducibility. Black-Gold II is a new and improved version of its predecessor, Black-Gold (Cat # AG390). The advantages of Millipore’s Black-Gold II Myelin Staining Kit over Black Gold I are that it is more readily soluble, can be utilized at a higher concentration, produces a more uniform and consistent staining, takes less time to stain, and does not require post-staining intensification procedures.

The use of Black-Gold II is tailored to studies using formalin-fixed, non-solvent processed tissue. The technique stains large myelinated tracts dark red-brown, while the individual myelinated fibers appear black. This novel tracer can be used to localize both normal and pathological myelin. Black-Gold II can demonstrate and characterize specific myelin changes associated with exposure to diverse neurotoxicants including kainic acid, methamphetamine, acrylamide, domoic acid, 3-nitropropionic acid, Fluoro-Gold and isoniazid.

The Black-Gold II Myelin Staining Kit also comes with sodium thiosulfate and cresyl violet. The sodium thiosulfate solution is required for extracting excess Black-Gold II stain. Whereas the cresyl violet is a Nissl stain that colors cell bodies a brilliant bluish hue and is used as a counter stain with Black-Gold II.


Black Gold II Purity: No detectable amount of uncomplexed gold was found.

Black Gold II Illumination: Bright field or dark field.

Black Gold II Solubility: Freely soluble in water, saline, or dilute acids.

Components

Black-Gold II: 150mg dry powder, yellow in color.

Storage and Stability

The kit can be stored at room temperature. Ideally, the Black-Gold II powder should be kept in a desiccator, because of its hygroscopic nature. The dry powder, if unopened and stored properly, is useable for up to one year from date of receipt. Once resuspended the Black-Gold II staining solution should be stored in the dark at 4°C and is good for up to 3 months.

TOXICITY: Although the compound appears to be of low toxicity, it has not been extensively evaluated and therefore routine laboratory caution should be exercised. Not intended for human consumption.
