摘要： Methods and apparatus are provided for serving ice cream with a chemically-heated ice cream scoop. The scoop comprises a bowl and a handle with an interior cavity filled with a nontoxic, supercoolable salt solution. The salt solution may be selectively crystallized by triggering an activator in fluid communication with the solution. Crystallization evolves a significant amount of heat that is used to elevate the temperature of the scoop bowl, thereby decreasing the cutting force required to separate a serving of ice cream from a storage container and reducing adherence of the ice cream within the scoop bowl. After use, the scoop may be recharged by elevating the temperature of the crystallized solution above its crystallization temperature. The process of crystallization, melting, and supercooling may be repeated indefinitely.

摘要： An isolated protein which is at least partially encoded by a polynucleotide sequence encoding a novel sulfotransferase is provided together with a composition which includes the isolated protein. A transgenic organism transformed by a polynucleotide encoding a protein which is at least partially encoded by a novel sulfotransferase is also provided. The invention also includes a process for in-vivo and in-vitro making a sulfated polysaccharide from an unsulfated polysaccharide or increasing the sulfur content of an already sulfated polysaccharide.
