Before use, the bottle should be removed from the refrigerator and equilibrated to room temperature and centrifuged before opening the cap for use. Samples should be restored to the sealed state as soon as possible after opening.How to use (take qPCR experiment as an example)1. Amplification template preparationThe samples to be detected were diluted with TE (10 mM Tris-Cl, pH 8.0,1 mM EDTA), and the concentration after dilution was as close as possible to the range of 0.05-10 ng/µL. The samples were placed on ice at 4°C and set aside.2. Standard dilution: according to the following table, firstly dilute Human DNA Standard 1 (100ng/uL) with TE to make 5 different concentrations of standards according to the table below. 10ng/µL of DNA Standard 1 (Std. 1) can be stored stably at -20℃ for 1 month; Std2-5 can only be used on the same day, and should be placed at 4℃ or on ice when not in use for the time being after preparation. When not used temporarily after preparation, it should be stored at 4℃ or on ice.styleCorresponding concentration (ng/µL)Minimum dilution volume (in µL)Std.11010 [100 ng/µL DNA Standard 1] + 90 TEStd.22.520 [Std. 1] +60 TEStd.30.62520 [Std. 2] +60 TEStd.40.1562520 [Std. 3] +60 TEStd.50.039062520 [Std. 4] +60 TE3. qPCR reaction system preparationThe cryopreserved reagents to be used were completely thawed and mixed by inversion several times before preparation, and then briefly centrifuged and prepared for use. 20 µL of the base reaction system was as follows.The base reaction system for 20 µL was as follows:reagents20µL reaction system2×qPCRMix10µLPrimerMixXµLProbeMixXµLTemplate4µLddH2OMake up to 20 µLNote: High Rox model: add 1 µL of 50×High Rox per 50 µL of reaction system; Low Rox model: add 1 µL of 50×High Rox per 500 µL of reaction system.Usually, better results can be obtained with a primer concentration of 0.2 µM, and 0.1-1.0 µM can be used as a reference for setting the range.The concentration of the probe used is related to the fluorescent quantitative PCR instrument used, the type of probe, and the type of fluorescent labeling substance, so please refer to the manual of the instrument or the specific requirements for the use of each fluorescent probe for the adjustment of the concentration during actual use.Prepare a sufficient amount of reaction system mixture as required. After the reaction system has been prepared and mixed thoroughly, add 16 µL per well to the reaction wells. Then add the prepared standard and diluted sample into the corresponding reaction wells, the volume of addition is 4µL/well. TE was added to the blank control tube, and the same amount of TE was added at 4 µL/well.It is recommended to use 20 µL for the reaction, if you need to perform a smaller system reaction, reduce the system components in equal proportion.4. qPCR reaction programThe following is an example of our GoldStar Probe Mixture reaction conditions, which should be improved and optimized according to the PCR product template, primer structure and target fragment size.movetemptimingcirculatepremutability95°C10min1denaturation95°C10sec55Annealing/Extension60°C30sec5Data analysis1. Standard curve productionThe standard curve was plotted with reference to the Excel sheet for data processing. The correlation coefficient R2 of the standard curve should not be lower than 0.98, and the slope should be between -3.1 and -3.6 when the Ct value is the vertical coordinate. If the parameters of the standard curve are unreasonable, it is recommended to repeat the experiment... Read More | Store at +4°C. Store under desiccating conditions.

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 | Inquire |
