Notes: Cacodylic acid has been widely used in buffers for electron microscopy techniques.{36150} It has also been used to introduce arsenic into proteins for single-wavelength anomalous diffraction (SAD) phasing in protein crystallography.{36147} In rats exposed to carcinogens, cacodylic acid increases the likelihood of tumor formation in the bladder, kidney, liver, and thyroid gland at concentrations as low as 50 ppm for the bladder.{36149}
