This product consists of 6 linear double-stranded DNA fragments, with sizes ranging from 100 bp to 2000 bp, specifically 100 bp, 250 bp, 500 bp, 750 bp, 1000 bp, and 2000 bp. The 750 bp band is highlighted with a concentration 2.5 times higher than the other bands, facilitating observation after electrophoresis.2. In 5 ul of this product, the content of the regular bands is approximately 30 ng, while the highlighted band contains about 75 ng.3. The product is preserved in 1x Loading Buffer and can be directly used for electrophoresis, making it convenient to use.4. This product is not suitable for polyacrylamide gel electrophoresis.Recommended Electrophoresis Buffer and Agarose Gel Concentration:This product is recommended to be used with 1x TAE electrophoresis buffer, with a suggested agarose concentration of 1.5% to 2.0%. For electrophoresis of smaller fragments, it is recommended to use GelRed nucleic acid dye.Usage Instructions:1. Prepare an agarose gel containing a nucleic acid dye, such as EB or GelRed.2. The concentration of the agarose gel has a significant impact on DNA electrophoresis. The recommended agarose gel concentration for this product is 1.5% to 2.0%.3. It is suggested to use 1x TAE buffer, with an electrophoresis voltage not exceeding 10 v/cm.4. For common 3.5 mm sample wells, a loading volume of 3 to 5 ul is recommended, with an appropriate increase for wider gel wells.5. Run the electrophoresis to the appropriate distance: For nucleic acid dyes such as EB, Goldview, and GRBlue, the bromophenol blue front should not exceed two-thirds of the gel, otherwise, smaller fragments may weaken due to the detachment of the nucleic acid dye from DNA. For dyes like GelRed, longer distances can be used as long as the smallest fragment does not run out of the gel. Generally, the bromophenol blue indicator band should be at least 1 cm away from the edge of the gel.6. After electrophoresis, observe the bands under a UV lamp.7. The 5x Loading Buffer included in the product is used for mixing with the samples to be tested before loading, containing both bromophenol blue and xylene cyanol as indicators.Product componentD665544Component100 T500TStorageD665544ADNA Ladder (100-2000bp)500 µL5× 500 µL-20℃.

The pre prepared PCR mixture makes the operation simpler and faster, and can minimize human error and contamination to the greatest extent Taq MasterMix is a premixed system composed of Taq DNA Polymerase, Mg2+, dNTPs, as well as PCR stabilizers and enhancers, with a concentration of 2 ×. The pre prepared PCR mixture makes the operation simpler and faster, and can minimize human error and contamination to the greatest extent possible. The original MasterMix formula results in high yield, strong repeatability, and good stability of amplified products. This product has been added with a dye (blue), and can be directly subjected to electrophoresis detection after the reaction is completed. The amplified PCR product has an "A" base attached to its 3 'end, making it suitable for direct use in T/A cloning. Mainly suitable for PCR amplification of DNA, DNA sequencing and other experiments.

Quality control:After testing, there was no exogenous nuclease activity; PCR method for detecting residual DNA without host; Can effectively amplify single copy genes from multiple genomes.Usage:The following is an example of a PCR reaction system and reaction conditions for amplifying a 1 kb fragment using human genomic DNA as a template. In practical operation, corresponding improvements and optimizations should be made based on the template, primer structure, and target fragment size.1.

The amplification efficiency of Taq DNA Polymerase in this product is 2 kb/min.3) The number of cycles can be set based on the downstream application of the amplification product. If the number of cycles is too small, the amplification amount is insufficient; If there are too many cycles, the probability of mismatches will increase, and non-specific backgrounds will be severe. So, while ensuring product yield, the number of cycles should be minimized as much as possible... Read More | Inquire | Inquire | Format:1-ComponentEnzyme:Horseradish peroxidase |
