Abstract: A modular suspension buffer for a vehicle having customizable hardness and height to provide various combinations of initial contact softness and non-linearly increasing resistance during compression so as to improve driving stability, loading capacity, off road performance, and/or ride comfort while extending the operational lifespan of the vehicle suspension system. Specifically, a universal modular coil spring buffer having a plurality of modules arranged in different configurations adaptable to be inserted in the gap of a coil spring of a vehicle to prevent shocks. The different configurations of a primary module and a plurality of secondary modules can be employed for different vehicles with different coil spring dimensions and based on the distance between the adjacent coils. The buffer lessens the compression to the coil spring thereby minimizing oil leaks caused from the shocks.

Abstract: The invention is a method for the isolation of molecules of interest using tubes in which at least a portion of the inner walls of the tube are coated with microbeads that are coated with a capture reagent to bind the molecule of interest. The microbeads may be glass or polymer beads. The invention is a method and apparatus for preparation of the tubes for use in the method of the invention. The invention is a method for determining ratios of guanine nucleotides bound to guanine-nucleotide binding proteins.
