A reinforced bulk bin, and methods for making same, wherein a collapsible bulk bin, preferably fabricated from paper, paperboard andor corrugated paperboard, is provided with a reinforcing plastic sleeve, which is placed on the bin while in its collapsed configuration. Such radiation is of detectable amplitude and contains sufficient information to determine the time-dependence of the strain wave with unprecedented subpicosecond, nearly atomic time and space resolution. Spontaneous coupling of the carbohydrate and the protein components under very mild conditions provided glycoconjugates containing up to 37 carbohydrate hapten units per carrier protein molecule.
