Typical applications include clone screening with DNA / RNA probes in Southern/northern blots and immunological screening with antibodies in western blots.
The units incorporate precision lapped surfaces to ensure uniform blotting membrane contact and a leak proof gasket. These prevent lateral transfer of samples – smudging – by ensuring that a complete vacuum is formed. Six thumbscrews ensure even and tight sealing for fast sample suck down. Dot blotters are available in 48 and 96 well versions and slot blotters in 24 and 48 well.
