Polyunsaturated lipids are susceptible to an oxidative attack, typically by reactive oxygen species, resulting in a well-defined chain reaction with the productionLipid peroxidation is the degradation of lipids that occurs as a result of oxidative damage and is a useful marker for oxidative stress. Polyunsaturated lipids are susceptible to an oxidative attack, typically by reactive oxygen species, resulting in a well-defined chain reaction with the production of end products such as malondialdehyde (MDA). Lipid peroxidation may contribute to the pathology of many diseases including atherosclerosis, diabetes, and Alzheimer′s.Lipid peroxidation (MDA) assay kit has been used to determine the levels of malondialdehyde (MDA).Suitability: Suitable for the measurement of malondialdehyde (MDA) in a variety of samples including tissue, cells and plasmaPrinciple: In this kit, lipid peroxidation is determined by the reaction of MDA with thiobarbituric acid (TBA) to form a colorimetric (532 nm)/fluorometric (λex= 532/λem= 553 nm) product, proportional to the MDA present...

Firefly Product introduction：Reporter gene detection is an important tool for analyzing the interaction between potential cis elements (such as promoters, enhancers and silencers) and trans acting factors in the flanking region of structural genes in the field of modern molecular biology. Firefly luciferase is widely used in gene regulation and drug screening. Firefly luciferase is a protein with a molecular weight of about 61 KD. In the presence of ATP, magnesium ions and oxygen, it can catalyze the production of oxyluciferin from luciferin. In the process of luciferin oxidation, it will produce a light signal. The optical signal of this kit is a kind of instantaneous light, which needs to be detected immediately after adding the working solution. The half-life of optical signal is about 5 min.Instruction：1.Working fluid configuration ( 1 ) Restore all components to room temperature. ( 2 ) The component B ( stock solution ) was fully diluted with component A to prepare a 0.2 mg / mL firefly luciferase working solution, which was vortexed and shaken to ensure full mixing. Note : The firefly luciferase working solution cannot be repeatedly frozen and thawed. If the dosage of a single experiment is small, it is recommended to subpackage according to a single dosage. At room temperature, the activity decreased by about 10 % after the working solution was configured for 3 h, and the activity decreased by about 25 % after 5 h. 2.chemiluminescence value detection ( 1 ) The cell culture plate was taken out from the incubator and incubated at room temperature for 20 min to restore it to room temperature ( 22-25 ° C ). ( 2 ) Add the same volume of firefly luciferase working solution with the medium to the culture plate and mix well. ( 3 ) Incubation at room temperature for 5 min. Note : The incubation time can be adjusted according to cell type and cell number. ( 4 ) The values were read by multifunctional microplate reader or chemiluminescence instrument ( instrument parameters : the determination time was 10 s, the determination interval was 2 s ).Matters needing attention：1. please centrifuge the product to the bottom of the tube immediately before use, and then conduct subsequent experiments. 2. the strongest wavelength of bioluminescence catalyzed by firefly luciferase is 560 nm. 3. to prevent interference between holes, it is recommended to use white opaque orifice plate.Recommendation：Component B is recommended to use sterile water in advance to configure 2 mg / mL storage solution, A component and B component configured as storage solution, and small batch packaging according to the experimental requirements. The detection working fluid is recommended to be used now to avoid repeated freezing and thawing. Component：One-Step Firefly Luciferase Assay Buffer；D-Luciferin Scope of application：Mainly used for ADCC detection... Read More | Inquire |
