Abstract:
The present invention relates to a method for purifying, modifying and immobilizing recombinant protein. The method utilizes genetic engineering to tag a DNA sequence encoding a target protein with a specific tag and express the vector to obtain a recombinant protein. The recombinant protein is then purified and modified by an affinity column and modification reagent. After exchanging the recombinant protein with a decoupling reagent, the recombinant protein is immobilized onto a specific substrate. The method, combining steps of purification, modification and immobilization, provides convenience to using recombinant protein. The omission of the use of dialysis or molecular sieve leads to a shorter period dedicating for removing excessive reagents and the increase of efficiency of recombinant protein recovery.
Abstract:
A card with an attachment structure for a disc comprises a card and an attachment structure, in which the attachment structure is disposed on said card. The attachment structure is used to attach a disc on the surface of the card so as to form the card and the disc into one body. Thereby, a user can show his idea and feeling through words on the card and images or music in the video/audio disc.
