Do not store together with: Oxidizing agent. 4. Contaminated or leaked out substrate solution from damaged bottles should not be used anymore and has to be destroyed.5. Use isolated containers with some cool bags for transport.6. Spontaneous decay will increase the background. If stored at room temperature, the velocity of the decay will increase. Thus, both storage and transport at room temperature should be avoided. Nevertheless, the activity of the solution is not affected by storage at room temperature. The solution still works beyond the expiry date, but some applications, especially those including visual evaluation, may be hampered by increased background. 3、Effective Components and Principle of FunctionIn different buffer solutions (pH = 9.5), with supplementation if required, the effective componentpara nitrophenyl phosphate (pNPP) is dissolved. Alkaline Phosphatase transfers the phosphate residue to an acceptor. Under alkaline conditions a yellow colour occurs, resulting from the formed nitrophenol. 4、Biosafety informationThis mixture is not classified as hazardous in accordance with Regulation (EC) No 1272/2008； 5、Advantage1. Signal yield comparable to competitor ready-to-use solutions2. Broad measurement range3. Very low background signals4. Very low blank drift during long-term storage (<0.15 AU within 24 months)5. High colour stability after reaction stop with this product and other commonly used stopping solutions 6、Instruction for usageFor bottling consider the following instructions:• Work in a dust free and darkened room.• Keep the solution as cool as possible.• Avoid contact of the solutions with any metal parts• Clean all instruments and vessels very extensively.• Wear powder-free gloves during bottling.• Close the bottles immediately to minimize the influence of light and dust.• Use clean bottles that are impermeable to light made from HDPE or PP. 7、 General Instructions for the Use in Blotting Systems Only qualified laboratory staff, who are familiar with the basics of immunological methods, are allowed to use these solutions.The substrate solutions can be used in qualitative and quantitative ELISA procedures.When using 96-well microtiter plates, adding 100 µL of substrate per well after incubation and washing is recommended. After substrate incubation the reaction can be stopped and the photometric measurement can be carried out. Using higher incubation temperatures (37° C) may shorten the incubation time. The reaction can be stopped by using the special developed solution stop. The use of other commercially available stop solutions cannot safely exclude a further increase of the signal. Addition of a stopping solution does not change the general shape of the spectrum. The unstopped and the stopped solution should be measured at 405 nm and the background correction: should be measured at 620 nm... Read More | GoldStar Probe Mixture is a premixed system specifically designed for real-time fluorescence quantitative PCR using probe methods (TaqMan, Molecular Beacon, etc.), with a concentration of 2 x, containing GoldStar Taq DNA Polymerase, PCR Buffer, dNTPs, and Mg2+. The operation is simple and convenientGoldStar Probe Mixture is a premixed system specifically designed for real-time fluorescence quantitative PCR using probe methods (TaqMan, Molecular Beacon, etc.), with a concentration of 2 x, containing GoldStar Taq DNA Polymerase, PCR Buffer, dNTPs, and Mg2+. The operation is simple and convenient. Mainly used for detecting genomic DNA target sequences and RNA reverse transcription cDNA target sequences, such as gene expression analysis, copy number analysis, SNP genotype analysis, etc., suitable for fluorescence quantification using different types of probe methods. The GoldStar Taq DNA Polymerase contained in this product is a chemically modified, novel and highly efficient hot start enzyme. It has no polymerase activity at room temperature, effectively avoiding non-specific amplification caused by non-specific binding of primers and templates or primer dimerization at room temperature. The enzyme activation requires incubation at 95 ℃ for 10 minutes. The unique combination of PCR buffer system and hot start enzyme significantly improves the amplification efficiency of PCR, with stronger fluorescence signal and higher sensitivity, which can detect single copy templates. By using this product, a wider linear range can be obtained, resulting in more accurate quantification of the target gene. Suitable for all fluorescence quantitative PCR instruments that do not require ROX as a calibration dye.ROX dye is used to correct the fluorescence signal error between wells in quantitative PCR instruments, and is generally used in Real Time PCR amplification instruments from companies such as ABI and Stratagene. The excitation optical systems of different instruments vary, so the concentration of ROX dye must be matched with the corresponding fluorescence quantitative PCR instrument.Instruments that do not require ROX calibration (CW0932): Roche LightCycle 480, Roche LightCyler 96, Bio rad iCyler iQ, iQ5, CFX96, etc.Instrument requiring Low ROX calibration (CW2625): ABI Prism7500/7500 Fast, QuantStudio ® 3 System, QuantStudio ® 5 System, QuantStudio ® 6 Flex System, QuantStudio ® 7 Flex System, ViiA 7 System, Stratagene Mx3000/Mx3005P, Corbett Rotor Gene 3000, etc.Instruments that require High ROX calibration (CW2626): ABI Prism7000/7300/7700/7900, Eppendorf, ABI Step One/Step One Plus, etc.G665832Component5 mLStorageG665832A2×GoldStar Probe Mixture5×1 mL-20℃.
