Feb 16, 2024 · The sample mixture is first separated by the GC before the analyte molecules are eluted into the MS for detection. 1 They are transported by the carrier gas (Figure 1 (1)), which continuously flows through the GC and into the MS, where it is evacuated by the vacuum system (6). 1. The sample is first introduced into the GC manually or by an autosampler (Figure 1 (2)) and enters the carrier gas ...

May 10, 2024 · In 1928, Griffith proposed the “transforming principle” having observed that bacterial cells could take up foreign hereditary genetic material. 1 This led to the discovery of DNA as that genetic material, 2 a discovery that enabled great strides in science. In the 1960s, viruses were employed to transfer genetic material into animal cells in …

May 2, 2024 · Diagnostic testing is key in many areas including healthcare and preventative medicine, food safety and environmental monitoring. As such, analysts need appropriate and accurate assays suited to the sample type, analyte and testing environment that respect monetary, time and operator constraints.

Oct 28, 2024 · With these immense technological advances, the human genome project was completed in 2003. 9 In 2005, the first commercially available NGS platform, or second generation (2G) as it has become, was introduced, able to amplify millions of copies of a particular DNA fragment in a massively paralleled way in contrast to Sanger sequencing. 10 …

Apr 8, 2024 · Neuroimaging is a discipline that deals with the in vivo depiction of the structure, function and pharmacology of the central nervous system (CNS), particularly our brain, in a noninvasive manner. 1, 2 The past two decades have witnessed remarkable strides in the development of new anatomical and functional imaging techniques that can shed light on many critical aspects of human brain function ...

Feb 26, 2024 · Traditional next-generation sequencing (NGS) examines the genome of a cell population, such as a cell culture, a tissue, an organ or an entire organism.Its output is the “average genome” of the cell population. On the other hand, single-cell sequencing measures the genomes of individual cells from a cell population. 5 Nowadays, traditional methods are thus referred to as bulk sequencing to ...

Jan 24, 2024 · New to cell culture? Then look no further. Here you will find a basic overview of all things cell culture, from setting up a cell culture lab to understanding basic principles and fundamental techniques. A great starting point to springboard into the world of cellular biology.

Jan 24, 2024 · Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) are the two most common types of electron microscopy. TEM and SEM differ in how they work and what types of images they are able to capture. This article will overview SEM and TEM, including what they are, how they work, and how they compare to one another.<br /><br />

Jan 22, 2024 · What are the three types of RNA? Messenger RNA (mRNA) copies portions of genetic code, a process called transcription, and transports these copies to ribosomes, which are the cellular factories that facilitate the production of proteins from this code.Transfer RNA (tRNA) is responsible for bringing amino acids, basic protein building blocks, to these protein factories, in response to the coded ...
