GB003: A general purpose blotting paper (0.8 mm) made from pure raw materials with a high absorbency used as a membrane gel support. A thick paper recommended for the lysis / denaturation of colony or plaque lifts and Western blots. GB005: A thick (1.5 mm) highly absorbent paper recommended for applications where fewer layers of blotting paper must still ensure a high capacity. Recommended for semi-dry blotting of proteins. - Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind. Ensures that no contamination will occur during the transfer steps. - Manufactured and tested specifically for chromatographic and blotting techniques. Ensures the wicking capability and uniformity of capillary action that are important in obtaining clean and even transfers during blotting. - Convenient sizes available in sheets precisely cut to the most popular gel and transfer membrane sizes. Allows 'out-of-the-box' usage and eliminates sheet-to-sheet variations.
