Please refer to the table below.SDS-PAGE Resolving Gel Concentration Optimal Separation Range6%50-150kD8%30-90kD10 -80kD12%12-60kD15%10-40kD2.Prepare a 10% ammonium persulfate solution with ddH2O or other high-purity water. Solution of ammonium persulfate or its substitute is prone to failure and should be prepared freshly or kept frozen for multiple uses.3.Prepare the resolving gel according to the table below. For example, add 100µl of 10% ammonium persulfate and 4µl of TEMED into 10ml of 12% SDS-PAGE Resolving Gel Master Mix, mix well, and immediately pour into gel cassette. Overlay with the top layer of water-saturated butanol, isopropanol, 0.1% SDS or distilled water. Leave at room temperature (~25℃) until fully solidified (usually within 10-30 minutes). Note: The amount of polymerization catalyst in the table below is recommended for polymerization at 25℃. It can be adjusted appropriately according to the temperature. For example, when the room temperature is lower than 20℃, add more TEMED and 10% ammonium persulfate appropriately to promote gel solidification.ReagentsVolume of each component (ml) required for different volumes of SDS-PAGE resolving gel12% SDS-PAGE Resolving Gel Master Mix5101520305010% ammonium persulfate or its substitute0.050.10.150.20.30.5TEMED 0.0020.0040.0060.0080.0120.024.After complete polymerization of the resolving gel, remove the liquid used for sealing, and then prepare the SDS-PAGE stacking gel with 's SDS-PAGE Stacking Gel Master Mix. 5.If the prepared gel is not to be used on the same day, it can be stored at 4℃ for 1-2 days...

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 | Laccase is an enzyme, produced by ericoid mycorrhiza and ectomycorrhiza fungi.

Laccase can catalyse a number of substrates including medicinal drugs and halogenated pesticides. It utilizes oxygen for its catalysis. For these reasons, it might be useful in the biological degradation of micropollutants in wastewater treatment. Laccase catalyzes the oxidation of phenol containing compounds, including lignin, through the reduction of oxygen to water. The presence of mediators will allow the oxidation of non-phenlic compounds as well. The primary function of laccase is to degrade lignin in fungi... Read More | Store at +4°C.
