Abstract: Methods for preparing complex multivalent immunogenic conjugates that include simultaneously reacting a plurality or immunogenic-distinct polysaccharides with at least one protein to make the complex multivalent immunogenic conjugates. The simultaneous reaction involves reaction of a hydrazide group on one reactant with an aldehyde or cyanate ester group on the other reactant.

Abstract: Methods for venting or drying (e.g., lyophilizing) samples contained in a multi-well plate. One method involves providing a multi-well plate that includes wells that each contain a sample and define an opening substantially sealed with a filter element that permits permeation of at least one gas and substantially prevents permeation of microbes. Another variant includes introducing a sample into a well via an opening defined by the well, covering at least a portion of the well opening with a filter element, and permitting gas to enter or exit the well substantially only through the filter element. An assembly is also described that includes a multi-well plate and a sheet defining a plurality of caps, wherein each of the caps includes a microbe-impermeable filter element. Another multi-well plate assembly includes a filter positioned to extend across at least a portion of the well opening.

Abstract: The present invention is a method of preventing or reducing atherosclerosis or restenosis, and a pharmaceutical preparation used therefor. In particular, it is a method of preventing or reducing atherosclerosis or restenosis after arterial injury by treatment with a low dose of a microtubule stabilizing agent such as taxol or a water soluble taxol derivative. The low dose used in the present invention prevents artery blockage while minimizing any negative side effects associated with the drug.
