Understanding Battery Types, Components and the Role of Battery ...
May 30, 2024 · Batteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 4 Nonetheless, it was not until 1749 that the term "battery" was coined by Benjamin Franklin to describe several capacitors (known as Leyden jars, after the town in which it was discovered), connected in series. The term "battery" was presumably chosen based on the analogy to existing ...
B Cells, Memory B Cells and Plasma Cells: B Cell Activation ...
Mar 19, 2024 · B cells, also known as B lymphocytes, are immune cells that drive the humoral adaptive immune response.They are one of three types of lymphocyte in the adaptive immune response – the others being T cells and natural killer (NK) cells. 1 B cells are distinguished by their ability to produce antibodies (known as immunoglobulins (Ig) when attached to B cells via a transmembrane domain), and the ...
An Introduction to Transfection, Transfection Protocol and …
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 …
Genetic Modification Techniques and Applications
Jan 4, 2024 · As mentioned, different types of genetic modification can be made, including: Gene knockout – the removal or inactivation of a target gene.; Deletion mutation – the removal of one or more nucleotides from a genetic sequence.; Insertion mutation – the addition of one or more nucleotides into a genetic sequence.; Substitution mutation – the switching out of one or more nucleotides in a ...
GC-MS Principle, Instrument and Analyses and GC-MS/MS
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 ...
Neuroimaging Techniques and What a Brain Image Can Tell Us
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 ...
An Introduction to Culturing Bacteria - Technology Networks
Jan 24, 2024 · Whichever medium is chosen, this may be in liquid form as a broth culture, or agar may be added to set the media and allow bacterial cells to be grown on a solid surface.. Culture broth. Culture in liquid media, also known as a broth culture, gives the bacteria present easy access to the available nutrients compared to static bacterial colonies.
LC-MS – What Is LC-MS, LC-MS Analysis and LC-MS/MS
Jul 30, 2024 · Coupling liquid chromatography (LC) with mass spectrometry (MS) has provided scientists with a powerful tool to meet stringent analytical demands and their versatility and efficiency means LC-MS instruments have become desirable in many laboratories. In this article, we consider how LC-MS works, what it tells us and highlight some of the technique's strengths and weaknesses.
SEM vs TEM - Technology Networks
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 />
Phagocytosis vs Pinocytosis: Definition and Function
Mar 21, 2022 · Examples of phagocytes and phagocytic cells. Phagocytes are a specialized group of cells that perform phagocytosis efficiently. This group includes immune cells such as macrophages, neutrophils and monocytes.Each type of phagocyte has a set of cell surface receptors that can initiate phagocytosis whenever they sense a target particle or pathogen.
