The present invention provides multi-well plates and column arrays in which samples (e.g., cell lysates containing nucleic acids of interest, such as RNA) can be analyzed and/or processed. In one embodiment, the microfiltration arrangement is a multilayer structure, including (i) a column plate having an array of minicolumns into which samples can be placed, (ii) a discrete filter element disposed in each minicolumn, (iii) a drip-director plate having a corresponding array of drip directors through which filtrate may egress, and (iv) a receiving-well pla...
[ It is claimed:] [1.] A microfiltration apparatus for processing a plurality of fluid samples, comprising:a first plate having a plurality of columns, each column having (i) a first inner bore defining a lumen within the column, and (ii) an end region for receiving a filter medium within the column, said end region defining (a) a second inner bore having a diameter greater than that of the first inner bore and (b) a transition region that joins the second inner bore to the first inner bore;positioned within each column end region, adjacent said transiti...
