NOTE:  It is best to turn the cams in opposite directions to each other. Do not overturn as 
this will cause the glass plates to push upwards and the assembly will be more likely to 
leak. The unit is now ready for gel preparation and pouring. 

Always reverse the silicone mat after casting to avoid indentations from persisting. Never 
leave the casting up-stand with glass plates tightened into the casting base for long 
periods of time as this will also cause indentations in the silicone mat.  

The slide clamp version omniPAGE Mini also includes screws. This system can be used 
either with the slide clamps or screws as preferred by the user. For those that prefer to use 
the screws rather than clamps, the screws can be simply inserted into the screw holes. The 
clamps can be removed by placing each clamp in the fully open position and gently 
bending the clamp upwards from the slanted end. The holding pin will then slowly release, 
and the clamp can be removed. Screw based casting is required when using the triple 
sandwich plate method. 

 

Gel Preparation 

Care should be taken when selecting the pore size of the gel to be used. The 
pore size or % of gel determines the resolving ability given different sizes of 
protein. 

Gel percentage for various protein sizes are shown below:
