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 2x Taq MasterMix is a premixed system composed of Taq DNA Polymerase, Mg2+, dNTPs, PCR stabilizers, and enhancers. 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 does not contain dyes. After the PCR program is completed, an appropriate amount of sample buffer can be added as needed for electrophoresis operation. The amplified PCR product has an "A" base attached to the 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: T665627Component5mlStorageT665627A2×Taq MasterMix5×1ml-20℃.

In the case of low amplification efficiency, the concentration of primers can be increased; When non-specific reactions occur, the primer concentration can be reduced to optimize the reaction system.2.

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...

The lectin has a molecular weight of 110 kDa and consists of four identical subunits of approximately 27 kDa each. PNA is a carbohydrate-free protein that displays specificity towards ?-D-Gal(1-3)-D-galNAc. It has potent anti-T activity and can be used to distinguish between human lymphocyte subsets. PNA has been used in tumour tissue determination for transitional mucosa malignancies. The lectin also agglutinates neuraminidase-treated human erythrocytes at < 0.1 µg/ml after trypsin treatment of cells and its activity is inhibited by lactose and galactose. PNA lectin is provided as a white to light yellow lyophilized powder from a buffer containing 10 mM NH4HCO3. The purity is determined by SDS-PAGE, which generates one band at 25-27 kDa.● Ultrapure quality ● Strong anti-T activity ● Sugar specificity: ?-D-Gal-(1-3)-D-GalNAc ● Agglutinates rabbit erythrocytes at < 0.1 µg/ml after trypsin treatment of the cells ● Lyophilized powderProbe in histochemistry and immuno-histochemistry;Human erythrocyte/lymphocyte studies...

It is a disulfide-linked heterodimer composed of the 40 kD cytokine receptor like subunit and a 35 kD subunit. This cytokine is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. IL12 has been found to be important for sustaining a sufficient number of memory/effector Th1 cells to mediate long-term protection to an intracellular pathogen. Recombinant human IL12 protein, fused to His-tag at C-terminus, was expressed in insect cells using baculovirus expression system and purified by using conventional chromatography techniques...
