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.

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...

In the Purity:>90%, by SDS-PAGE visualized with Coomassie® Blue Staining.Description: DCX (doublecortin, N-GST chimera)contains 2 doublecortin domains and belongs to the doublecortin family. It is highly expressed in neuronal cells of fetal brain, but not expressed in other fetal tissues. In the adult, it is highly expressed in the brain frontal lobe, but very low expression in other regions of brain, and not detected in heart, placenta, lung, liver, skeletal muscles, kidney and pancreas. DCX is a microtubule-associated protein required for initial steps of neuronal dispersion and cortex lamination during cerebral cortex development. It may act by competing with the putative neuronal protein kinase DCAMKL1 in binding to a target protein. DCX may in that way participate in a signaling pathway that is crucial for neuronal interaction before and during migration, possibly as part of a calcium ion-dependent signal transduction pathway. It may be part with LIS-1 of a overlapping, but distinct, signaling pathways that promote neuronal migration. Defects in DCX are the cause of lissencephaly X-linked type 1 and subcortical band heterotopia X-linked... Read More |
