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
Western blot antibody. The secondary antibody is visualised through various methods such as staining, immunofluorescence, and radioactivity, allowing indirect detection of the specific target protein. Other related techniques include dot blot analysis, quantitative dot blot, immunohistochemistry, and immunocytochemistry where antibodies are used to detect proteins in tissues and cells by immunostaining, and enzyme-linked immunosorbent assay (ELISA). The name "western blot" is a play on the eponymously-named Southern blot, a technique for DNA detection developed earlier by Edwin Southern. Similarly, detection of RNA is termed northern blot and was developed by James Alwine, David Kemp, and George Stark at Stanford. The term "western
