This product is suitable for the Tris-Glycine electrophoresis system and contains premixed solutions for preparing the concentrated gel (upper gel) and the separated gel (lower gel). During the gel preparation process, there is no need to calculate the amount of each component, no need for dilution, and no need to add TEMED. Just mix the upper gel solution with the upper gel buffer and the lower gel solution with the lower gel buffer in a 1:1 ratio respectively and add the coagulant to gel, simplifying the operation steps for preparing SDS-PAGE gel. Multiple gels can be quickly poured, making the gel-making process more convenient. The upper layer of tape is colored, making the sample loading holes clearly visible and facilitating sample loading. The dry powder form of the coagulant provided with this product should be stored at 2-8℃, and after dissolution, it should be kept at -20℃.
