Gold (Au)
Gold is found as a free metal in nature, occurs in veins and alluvial deposits, and is associated with tellurides, quartz, and pyrite.
In pure form, it's an attractive metallic yellow color, but can be black, ruby, or purple in smaller quantities. As the most malleable and ductile metal, gold is typically alloyed for strength. It conducts heat and electricity, reflects infrared rays, and is mostly unaffected by air and chemicals. Some of gold's 18 isotopes are used in medicine to treat cancer and arthritis.

Electron Microscopy Sciences Alpha/Numeric Index Grid, Gold
By employing a rectangular mesh, the support value of the grid has been increased, offering a value intermediate between the most commonly used grid (200 Lines) and (300 Lines). Each grid rectangle is asymmetrical having different outlines in all four corners. This allows for the orientation of the grid to be determined at microscopic levels. The index feature enables the position of each grid to be identified with reference to the letters A-O along the horizontal axis and the numbers 1-15 along the vertical axis. The logo in the rim allows for precise orientation and aids in the identification of each side.

Sigma Aldrich Fine Chemicals Biosciences Aflatoxin B1 BSA Conjugate5MG
Aflatoxin B1 is the most toxic aflatoxin. Aflatoxins are hepatotoxic metabolites that are produced by molds such as Aspergillus flavus and Aspergillus parasiticus. Aflatoxins contaminate human food and animal feed. They are linked to liver cancer immune system suppression reduced growth rates losses in feed efficiency and death. They are naturally found toxic carcinogens and the most widely known mycotoxins. They mainly contaminate fruits vegetables and grains.
