| methyl aldehyde | <chemical> Commonly used fixative and antibacterial agent. As a fixative it is cheap and tends to cause less denaturation of proteins than does glutaraldehyde, particularly if used in a well buffered solution (buffered formalin, formal saline). Old formaldehyde solutions usually contain cross linking contaminants and it is therefore often preferable to used a formaldehyde generating agent such as paraformaldehyde. Formalin fumes, particularly in conjunction with hydrochloric acid vapour, are potently carcinogenic. (20 Jun 2000) |

| methyl blue | A sulfonated triphenylrosaniline dye used as a stain for cytoplasm, collagen, and Negri bodies, and as an antiseptic. (05 Mar 2000) |
| methyl bromide | <chemical> A volatile, toxic, colourless gas or liquid that is frequently used as a fumigant, it is similar in structure to chloroform. It is known to be a powerful ozone-destroying chemical, but it is broken down by some bacteria, thereis much scientific debate on how much danger methyl bromide poses to the ozone layer.
