How does the purification of water work? How does it get cleared as "purified"? What is the process of mass spectrometry? Explain. How can you synthesize ethanedioic acid in the laboratory? why is sand an magnesium sulphate added in chromatography of the leaf why is sand an magnesium sulphat...
Question: Explain the purpose of using a washing buffer in RNA extraction, and explain how an elution buffer differs from a washing buffer. RNA: RNA stands for ribonucleic acid, and one type is formed from DNA by a process of transcription...
which can be a silica gel in the case of mini-prep columns, but usually beads that can be covalently linked to antibodies or other ligand molecules. “Solid phase” does not necessarily mean a standing column; it can be beads
Your Western blotting experiments start long before you begin to work with your membrane. If your gel is sloppily made or you run it at an excessive voltage, your final results will suffer. If you cast your own gels, take extra care to ensure uniformity in their makeup. Select the right...

cell lysis, which can cause lower DNA yields to due to aggregation and degradation. The other components of the buffer also contribute to the osmolarity of the solution, but glucose, being a non-electrolyte, is a good choice because it does not interfere with the solution's buffer properties...
Naturally, your daily laboratory routine does not consist exclu- sively of sample separation. Preliminary work steps, for example, cell cultivation in shakers, incubators and/or fermenters, are also immensely important. The selection of the right equipment can always ease your daily routine to a...
In aggregate, this work reports the high-resolution structure of the most critical piece of the flagellar motor in three states. The structure suggests mechanisms for torque transmission and directional switching during chemotaxis in Salmonella and related bacteria. This structure also allows a large bo...
Also after some experiments with the home made TDR it became clear that this kind of analysis does not work well with cables shorter than two or three meters. With short cables the reflection arrived within the so called blind spot [79] and was close to invisible within the rising edge of...
assert.equal(eventEmitted, true, "sending an IPFS request does not emit an event") }) }) So we run our test by running the following: $ truffle test It tests our contract with the files in thetestfolder and shows the number of passed and failed tests. For this tutorial, we should ...
