Tabula (game) Tabula were reconstructed in the 19th century by Becq de Fouquières based upon this epigram. The game was played on a board nearly identical to a modern backgammon board with 24 points, 12 on each side. Two players had 15 pieces each, and moved them in opposing directions around the board, according to the roll of three dice. A piece resting alone in a space on the board was vulnerable to being hit. Hitting a blot, reentering a piece from the bar, and bearing off, all had the same rules as today. The only differences with modern backgammon were the
Northwestern blot then transferred to a filter membrane for detection. Detection occurs as bands become visible on the membrane and correlate with a particular molecule of interest. Subsequently, other similar blotting techniques were created with similar nomenclature to detect different molecules or interactions between molecules. These techniques include the Western blot (protein detection), the Northern blot (RNA detection), the Southwestern blot (DNA-protein interaction detection), the Eastern blot (post translational modification detection) and the Northwestern blot (RNA-protein interaction detection). Running a Northwestern blot involves separating the RNA binding proteins by gel electrophoresis, which will separate the RNA binding proteins based upon their size
