Overview: Overview: Antigen-antibody reactions are commonly used in immunological assays. In a traditional agglutination assay, the end product is a visible antibody-antigen complex that settles as visible particulate matter in the solution. In other cases, the reaction is invisible and wants the use of a specific enzyme or isotopic probes that can amplify the signal created by the antigen-antibody reaction, so that they can be detected with the naked eye or an ELISA/RIA reader1. Hemagglutination is a visible antigen -antibody assay in which soluble antibodies react with antigen on the surface of (red blood cell) RBC to form a ...

Introduction

Reduction reactions are very important in chemistry as they are effective processes for synthesizing new compounds from existing ones. In organic chemistry, a compound is said to be reduced if it acquires new hydrogen. There are diverse reagents for carrying our reduction reactions. Two of these are sodium borohydride (NaBH4) and lithium aluminum hydride (LiAlH4) - the latter is a more powerful reducing agent compared to the former. In this experiment, NaBH4 was used to reduce p-Nitrobenzaldehyde to form p-Nitrobenzyl alcohol. NaBH4was used over LiAlH4 in this experiment, because LiAlH4 would also reduce the nitro group of the aldehyde.

Introduction

Resource curse has been one of the most debated economic issues for the past four to five decades. Indeed, it refers to a theoretical approach that connects certain indicators of a country’s economic growth to its reliance on natural resources such as oil, gas, and minerals. According to a general belief (termed as ‘resource curse’), the countries that are rich in natural and non-renewable resource are characterized by lower levels of democracy, economic growth, and development as compared to the countries with less or no reliance on these resources (Sachs, and Wartner, 2001). On the basis of the ...

Q. 1. Explain how gel filtration chromatography (size exclusion chromatography) separates molecules on the basis of their mass/size.

A. In gel filtration, porous beads are packed into a column. The pores are of different size. The column is then packed with a buffer solution. This buffer solution is present inside the beads as well as around it. When molecules of different size pass through the columns, the smaller molecules pass through the pores and take a longer path. The larger molecules, however, travel around the beads. Thus, larger molecules travel faster than the ...

Protein degradation is a regulatory process of all living beings that helps to weed out proteins that are faulty in nature. The fault maybe in their sequence or folding. The proteins are degraded via ubiquitin-proteasome system (UPS). The proteasome is made up of an outer activating module and an inner core particle (CP), which in turn is made up of outer α subunits and inner β subunits. The α subunits guard a N-terminal gates pore, which open up when proteasome activators (PA) binds to it. The β subunits have the active sites that can broadly accommodate different faulty proteins for degradation. ...

Approach to reading a chest radiograph

An initial assessment is done to ensure that the radiograph belongs to the patient. According to Moskowitz (2011), once the initial assessment is done, the technical quality of the radiograph is determined. This entails assessing parameters such as rotation of the patient, exposure of the film and inspiratory effort of the patient. Moskowitz (2011) notes that rotations may in most cases symbolize abnormalities in the cardiac contour and can result in erroneous diagnoses. To make certain that the patient is not rotated the position of the medial ends of the clavicles needs to be equidistance from the spinous process. ...

Introduction

The discovery of restriction enzymes (REs), bacterial transformation, and agarose gel electrophoresis caused the sudden increase of popularity of molecular biology in the 1970s. Restriction enzymes allow the manipulation of specific sites of an organism’s genes and are commonly used in many laboratories worldwide. Restriction enzymes cut DNA in many different ways and can produce sticky ends and blunt ends (Weaver, 2012). The most abundant type of restriction enzymes is Type II, which require magnesium cations as cofactor (Pingoud et al., 2005). Aside from their popularity is recombinant DNA technology as a “cut and paste” tool, estriction enzymes can ...
