STAINING, PRACTICAL AND THEORETICAL 



MATAMOUNT 



(Edward Gurr) 



This mountant was designed for mounting cellulose acetate 

 strips in electrophoresis. Its use is described by Bodman (i960). 

 Cellulose strips processed by Bodman's technique are rendered 

 completely transparent and can be used as lantern slides for 

 projection purposes. 



MEEDOL BALSAM 



(Edward Gurr) 



Refractive index 1*515 



A xylol miscible mountant, pale amber in colour and hardly 

 distinguishable in appearance from Canada balsam in xylol. This 

 is one of the least costly of all resinous synthetic mounting media. 

 Unlike Canada balsam, but like the other synthetic mountants 

 described in this paragraph, Meedol balsam has the advantage of 

 remaining neutral indefinitely under normal conditions of storage 

 and handling. 



MICHROME MOUNTANT 



Refractive index 1*515 



A synthetic neutral mountant miscible with alcohol and with 

 xylol. Sections may be mounted directly from 95% alcohol if 

 desired. It does not cause the fading of stains even after several 

 years. However, Clearmount, which is odourless, is perhaps to be 

 preferred. 



S.Q.D. BALSAM 



(Edward Gurr) 



Refractive index 1*515 



An exceptionally quick-drying, synthetic, xylol miscible, 

 synthetic mountant, similar to Meedol balsam.
