Abstract: The present invention provides a method of interactive gaming applied to an interactive case and a tablet, wherein the interactive case is arranged to be attached on the tablet, and the interactive case includes a transmission port arranged to communicate with the tablet and a plurality of notches. The method of interactive game includes determining whether at least one accessory medal is connected to the notch; when one of the accessory medals is connected to one of the notches, retrieving a predetermined data stored in the connected accessory medal; identifying the connected accessory medal according to the predetermined data of the connected accessory medal; and performing an application corresponding to the connected accessory medal.

Abstract: A method is provided for purifying protein having steps of loading a sample containing proteins into a column containing an ion exchanger in a first direction to allow the ion exchanger to absorb proteins; and passing a salt solution through the column in a second direction opposite to the first direction to elute a target protein from the ion exchanger. The method is proven as capable of improving homogeneity of eluted target protein without combining minute and complicated techniques for protein purification. Therefore, the method is convenient, efficient and economic for purifying proteins.
