Storage fluid information
10mM Tris-HCl(pH 8.4) 10mM EDTA 0.02% BPB 5% glycerinumThe product concentration is about 130μg/ml Please store at 4℃ (please store at -20℃ for long-term storage)The 1Kb DNA Ladder is composed of 13 double strands of DNA, and the doubled concentration of 1kb and 5kb is helpful to distinguish different bands. Below 1kb, three bands of 250bp, 500bp, and 750bp are added, and the size of the short fragment can be roughly calculated based on this. The concentration of the four bands of 6kb, 7kb, 8kb, and 10kb is halved, which is beneficial to obtain a better separation effect. This product already contains 1× Loading Buffer. You can take 2-6μl for direct electrophoresis according to the needs of the experiment. The electrophoresis image is clear, convenient and practical. The 13 bands of this product from small to large are: 250bp, 500bp, 750bp, 1kb, 1.5kb, 2kb, 3kb, 4kb, 5kb, 6kb, 7kb, 8kb, 10kb. If the loading volume is 5μl, 1kb and 5kb bands are 100ng; 6kb, 7kb, 8kb, and 10kb bands are 25ng; and the remaining bands are 50ng.
