| Description | Chloroplast 3-phosphoglycerate kinase (PGK) is a key enzyme in the Calvin cycle. Detection Principle: Chloroplast 3-phosphoglycerate kinase catalyzes the reaction of 3-phosphoglyceric acid and ATP to produce 1,3-bisphosphoglyceric acid. The latter, under the action of glyceraldehyde-3-phosphate Chloroplast 3-phosphoglycerate kinase (PGK) is a key enzyme in the Calvin cycle. Detection Principle: Chloroplast 3-phosphoglycerate kinase catalyzes the reaction of 3-phosphoglyceric acid and ATP to produce 1,3-bisphosphoglyceric acid. The latter, under the action of glyceraldehyde-3-phosphate dehydrogenase and NADH, produces glyceraldehyde-3-phosphate and NAD⁺. The enzyme activity of 3-phosphoglycerate kinase is determined by measuring the decrease in NADH.Component96TStorageExtraction Buffer 1100 mL2-8℃Extraction Buffer 2100 mL2-8℃Reagent 11EA-20℃.

Sample Extraction (Chloroplast Isolation)Weigh approximately 0.1 g of plant tissue sample. Add 1 mL of Extraction Buffer 1 and homogenize rapidly in an ice bath. Centrifuge at 1,600 rpm, 4°C for 5 minutes. Discard the pellet. Take the supernatant and centrifuge again at 5,000 rpm, 4°C for 15 minutes. Discard the supernatant and keep the pellet. Add 1 mL of Extraction Buffer 2 to the pellet. Vortex vigorously for 15 seconds. Place on ice (or in a refrigerator) and incubate at 4°C for 15 minutes. Centrifuge at 13,000 rpm, 4°C for 5 minutes. Collect the supernatant for assaying the chloroplast 3-phosphoglycerate kinase (PGK) enzyme activity.Important: The entire chloroplast extraction process must be maintained at 4°C.Note: If increasing the sample amount, maintain a tissue mass (g) to Extraction Buffer volume (mL) ratio between 1:5 and 1:10.2. Assay Steps2.1 Preheat the microplate reader for 30 minutes. Set the wavelength to 340 nm and the temperature to 25°C.2.2 Thaw all reagents to room temperature (25°C).2.3 Add reagents sequentially to a 96-well plate:ReagentTest Well (µL)Sample20Reagent 110Reagent 210Reagent 310Reagent 4140Mix well and incubate at room temperature (25°C) for 10 minutes.Reagent 510Mix gently. Under room temperature (25°C) conditions, read the absorbance at 340 nm at 30 seconds (A₁) and then again after 10 minutes (A₂). Calculate ΔA = A₁ - A₂.注：Notes:(1) If ΔA is close to zero, the reaction time can be appropriately extended to 20 minutes before reading A₂. If the reaction time is changed, the new time (T) must be substituted into the calculation formula. Alternatively, the sample volume can be increased (e.g., to 40 µL, with a corresponding decrease in Reagent 4 volume); the new sample volume (V₁) must then be substituted into the calculation formula.(2) If the decrease trend is unstable, read the absorbance every 20 seconds and select a linearly decreasing time period for calculation. The corresponding A values for this period should be used to calculate ΔA and substituted into the formula.(3) If the initial absorbance A₁ is too high (e.g., >2, as in dark green plant leaves with high pigment content), consider appropriately reducing the sample volume; the new sample volume (V₁) must be substituted into the calculation formula. Alternatively, add a small amount of activated carbon to the sample, mix, let stand for 5 minutes, then centrifuge at 12,000 rpm, 4°C for 10 minutes, and use the supernatant for assay.(4) If ΔA is greater than 0.5, reduce the reaction time (e.g., to 5 minutes) or reduce the sample volume (e.g., to 10 µL). The changed reaction time (T) and/or sample volume (V₁) must be substituted into the calculation formula.3.

We also have transposase library construction kits for 50 ng and 1 ng of human genomic DNA starting, in order to get a higher quality library, it is recommended to use different kits for different starting amount of DNA. Products IntroductionThis kit is developed for Illumina's high-throughput sequencing platform and provides the enzyme premix system and reaction buffer for genomic DNA library construction, including all components except PCR primers. Compared with the traditional library construction kits, this kit adopts the new transposase method for library construction, which can complete DNA fragmentation, end repair and junction reaction in one simple enzymatic reaction, significantly reducing the amount of template, reducing the number of experimental steps, and shortening the time of library construction; it adopts the high-fidelity DNA polymerase for library enrichment, and the preference-free PCR amplification can expand the coverage area of the sequence, which can be used for efficient and effective sequencing. The use of high-fidelity DNA polymerase for library enrichment and preference-free PCR amplification broadens the coverage area of the sequence and enables efficient preparation of DNA libraries for Illumina's second-generation sequencing platform. The kit is suitable for use with a starting template DNA input of 5 ng, and all reagents in the kit have been subjected to stringent quality control and functional validation to maximize the stability and reproducibility of library construction. Product Features● DNA fragmentation and junction ligation in one step.● Ultra-fidelity amplification minimizes amplification preference.Provide your own instruments, kits and consumables1. Magnetic frame: DynaMagTM-2 is recommended.2. DNA purification and recovery kit: It is recommended to use DNA purification and recovery kit by magnetic bead method.3. Library PCR primer kit: It is recommended to use transposase method for second generation sequencing multi-sample primer kit.4. Anhydrous ethanol, deionized water (pH between 7.0 and 8.0).5. Reaction tubes: It is recommended to use low adsorption PCR tubes and 1.5 ml centrifuge tubes. Tips: It is recommended to use high quality filter tips to prevent contamination of kits and library samples. Pre-experiment Preparation and Important Notes1. Avoid repeated freezing and thawing of reagents.2. PCR products are easily contaminated due to improper operation, resulting in inaccurate results. It is recommended to isolate the PCR reaction system preparation area from the PCR product purification area, and to use special pipettes to clean the experimental areas at regular intervals.3. Bead purification: the beads should be equilibrated to room temperature before use, all operations on the beads should be carried out at room temperature, 80% ethanol should be dispensed freshly, the beads should be rinsed and dried until the surface is free of liquid reflections and has a frosted appearance, insufficient drying of the beads will cause ethanol residue that will affect the subsequent experiments, and over-drying of the beads will affect the efficiency of DNA recovery.4. The kit is suitable for human genomic DNA library construction, if the DNA sample is a PCR product, it should be ensured that its length>.500 bp, since transposases do not work on DNA ends, it is recommended to extend the PCR product by 50-100 bp at each end of the PCR product to avoid low coverage of the ends for sequencing. Sample PreparationDNA purity requirements: A260/A280 = 1.8-2.0. Sample DNA: dissolve in ultrapure water. DNA Quantification: Too much or too little DNA will affect the quality of the library. It is recommended to use Nano to test the purity of the genomic DNA and then use Qubit to test the concentration of the genome (do not use any absorbance-based assay for template quantification).

Library quality controlDetermination of library concentrationIn order to obtain high-quality sequencing results, accurate quantification of DNA libraries is required, and the first recommendation is to use Real-timePCR methods are used for absolute quantification of DNA libraries. Additionally, fluorescent dye methods such as the Qubit method or the fluorescent dye picogreen method can be used; do not use quantification methods based on absorbance measurements here. The following approximate formula can be used to convert the molar concentration of the DNA library.
