XBLOT P100 is a temperature controlled hybridization system useflul for Western (W), Northern (N) and Southern (S) Blots analysis. The pressing and spreading device allows the uniform distribution of the reagents on nytrocellulosa o di nylon (PVDF) filters. The filters consist of transferred elctrophoresed proteins (W) DNA (S) or RNA (N); each filter is perfectly sealed in a plastic folder containing the proper reagents for each application. Small quantities of reagents are needed (sufficient amounts to keep the filter wet). The continuous rolling movement facilitates the binding of the antibody to the antigen on the filter (W) or labelled probe for DNA or RNA (S and N). Multiple filters can be handled simultaneously.
