The present inventors have found that certain preparations containing LPS andor lipid A variants, derivatives, andor analogs demonstrate non-pyrogenic properties and exhibit anti-viral activities. Using these spin editing techniques, magnetic resonance signals of one or more unwanted chemicals chemicals can be suppressed, so that the signal of a first set of chemicals can be obtained without signals from the one or more unwanted chemicals. 05 mm and a ten-point mean roughness of equal to or smaller than 5. The interconnect also includes support members configured to physically contact the component, to prevent flexure of the component due to pressure exerted by the force applying mechanism.
