摘要:
Described herein are methods and devices for ligating nucleic acids or nucleic acid fragments as well as methods for transforming or transfecting cells with exogenous DNA. The methods and devices generally involve exposing the nucleic acids, nucleic acid fragments, and/or cells to an electromagnetic field, for example, a mini-current electromagnetic field, while performing the steps of ligation or transformation. The methods and devices provide numerous advantages over conventional ligation and transformation techniques and systems such as reduced reaction times, no heating requirements, and reduced amounts of reagents. Finally, as shown in the examples below, the methods and devices described herein are more effective compared to conventional ligation and transformation techniques and systems.
摘要:
Described herein are glucose and insulin sensors. The sensors are composed of host cells with DNA specifically designed to produce fluorescence when the cells come into contact with glucose and/or insulin in the sample. Once the fluorescence has been quantified, it can be correlated with the amount of glucose and/or insulin present in the sample.
摘要:
Described herein are devices and methods for simultaneously expressing amyloid precursor protein and TonB protein. For example, the biological devices and methods described herein increase the production of these two proteins while also reducing the cost, making these proteins more widely accessible for medical research purposes, including for the development of diagnostic tests for Alzheimer's disease. The amyloid precursor protein and TonB protein produced by the devices and methods described herein, as well as the devices themselves, can be used in experiments designed to model the interactions between metals and β-amyloid that are characteristic of Alzheimer's disease.
摘要:
Described herein are methods for enhancing the production of phenolic compounds from Theobroma cacao. For example, the devices and methods described herein increase the production of phenolic compounds from cocoa plants, which has industrial and economic value. The phenolic compounds produced by the devices and methods do not require the ultra purification that is common in conventional or commercial methods. The devices and methods described herein also enhance the growth rate of plants.
摘要:
Methods and devices for amplifying nucleic acids generally involve exposing the nucleic acid to an electromagnetic field, for example a mini-current magnetic field, while performing the steps of PCR. The PCR methods and devices provide numerous advantages over conventional PCR techniques and systems such as reduced reaction times, no heating requirements, and reduced amounts of reagents (e.g., optional use polymerases and primers). Additionally, the PCR methods and devices require significantly shorter reaction times (e.g., less than one hour) compared to conventional PCR techniques and systems (minimum 2 hours). Finally, as shown in the Examples, the PCR methods and devices amplify significantly more DNA compared to conventional PCR techniques and systems. Accordingly, the PCR methods and devices provide a more efficient and cost-effective way to perform PCR when compared to conventional PCR techniques and systems.
摘要:
Described herein are compositions and methods for effectively removing from soil samples. By isolating the oil from the soil sample, it is possible to accurately evaluate the different properties of the oil in the sample.
摘要:
A safe, environmentally-friendly anti-microbial composition is provided. The composition comprises an extract of barley and chelated mineral ions. A grape or lemon extract is optionally included. The composition is useful as a surface decontaminant or as a feed component.
摘要:
Described herein are biological devices and methods for using the same to produce oxidized zinc. The biological devices include microbial cells transformed with a DNA construct containing genes for producing a zinc-related protein, an alkaline phosphatase, and an alcohol dehydrogenase. In some instances, the biological devices also include a gene for lipase. The oxidized zinc compositions produced herein have numerous applications.
摘要:
