Abstract: This disclosure relates to reagents, compositions, methods for stabilising RNA in an RNA-containing sample by contacting the sample with guanidine and a metal ion to form a stabilised RNA-containing composition in which the metal ion is present at a concentration which is no more than 20 mM, and the metal ion is derived from a metal other than from a Group 1 or Group 2 metal.

Abstract: Apparatus for playing a game and comprising: a board having a grid of squares marked thereon, a set of player tokens which are allocated to respective players for placing on said grid; a set of markers each having a letter marked thereon and being arranged such that each may be placed on a corresponding square of said grid; a set of game cards each having a multiplicity of squares marked thereon, whereby in use selected markers can be removed from the grid by players and placed on squares of the game cards to construct words or phrases; and a set of question cards each having marked thereon a question. Each player throws a die to determine how far he can move his token across the board. Providing that the player can correctly answer a question read to him from a selected question card, he can remove a letter from the square on which he landed and use it to construct a word or phrase on his game card.
