Methods and compositions are provided for forming complexes between dsDNA and novel DNA-binding polymers comprising N-terminal thiophene-containing moieties which exhibit selectivity for T-A base pairs. They comprise a liquid medium with a water content of up to 15 wt. One embodiment of the method comprises coupling the memory blocks to repeaters; and reading from the memory blocks. To install the skirt guard the hook is inserted into the skirt base channel alongside the bottom of the skirt and the hook fastens the skirt guard in the channel. The first portion and the second portion sealingly and movably abut against the first chamber and the second chamber respectively. The effect of the inhibitor is preserved to provide a more accurate determination of CETP activity in the fluid.
