chromatography, we know, is vital to the efficiency of a separation process. Protein A chromatography by virtue of its incredible ability to achieve high purity of biopharmaceutical products has made itself indispensable for downstream purification of biomolecules (Hammond et al.) Even though many variations of different chromatographic separations have been employed as ‘capture’ steps over the years, Protein A affinity chromatography has come to be used as the method of choice for direct ‘capture’ and

such as affinity chromatography, ion exchange chromatography, and gel filtration chromatography (also known as size-exclusion chromatography). In our experiment, the size-exclusion method was applied. This method uses a buffer to dissolve the biomolecules in a column that separates the protein by their size. The bigger molecules pass by miniscule beads that are condensed into a column, and the smaller molecules pass through the pores of the beads. This insures that the bigger molecules will go through

high rates of contamination by other microorganisms such as bacteria, fungi and other algae species. PBRs are stable environment for the growth of many organisms including algae. Moreover, photobioreactors offer the ability to produce specific biomolecules such as vitamins, lipids, and biopharmaceuticals. However, photobioreactors are expensive, requires special sophisticated equipment’s and not easy to construct. There are different types of PBRs such as vertical tubular, bubble column, flat panel

A scientific revolution is underway that promises to spare millions of animals from suffering and death. Countless animals are used every year in the United States and abroad to assess the potential health hazards of cosmetics, soaps, household cleaners, pesticides, drugs, and other chemicals and products to which people might be exposed. In these assessments, chemicals are applied to the animals’ eyes and skin or injected into their bodies, or the animals are forced to ingest or inhale them. Crude

INTRODUCTION * Cholesterol is the major sterol in the animal tissues. * Cholesterol is present in tissues and in plasma either as free cholesterol or as a storage form, combined with a long-chain fatty acid as cholesteryl ester. * In plasma, both forms are transported in lipoproteins * Plasma low-density lipoprotein (LDL) is the vehicle of uptake of cholesterol and cholesteryl ester into many tissues. * Free cholesterol is removed from tissues by plasma high-density lipoprotein

chemical reactions whose kinetics have been studied, some of the most interesting and complex are those which take place in living organisms. These reactions, when studied under non-biological conditions (lack of organisms and their various biomolecules), are often exceptionally slow: often hours or days, and sometimes even years are required before equilibrium is reached. Yet life requires seconds or even fractions of seconds to produce the same results, and it does this through the use of

The Sphingolipidoses are a group of Lysosomal Storage Disorders (LSDs), which individually are considered rare diseases; however, their collective incidence is approximately 1 in 5000-9000 live births. This number is dependent on the location and population, with some regions presenting a much higher proportion of cases than others. These diseases consequently together comprise a vast proportion of the healthcare system and therefore there is a need to investigate novel treatments as well as more

What is cholesterol? Cholesterol is an organic molecule part of the classification of biomolecules known as lipids. It is a sterol, or steroid alcohol, that is extremely important as it is a major structural component of the cell membrane in animal cells and also a precursor for the production of steroid hormones (oestrogen and testosterone), bile salts, bile acids and vitamin D. Cholesterol is a waxy substance with the chemical formula C27H46O, it consists of three 6-memebered rings and one 5-membered

Karen Bleile Genetic Report for Designer Babies Biology 111-112 / J. Thomson October 30, 2012 In the 21 century the term designer babies made the transition from sci-fi movies into the real world where it is defined as “a baby whose genetic makeup has been artificially selected by genetic engineering combined with invitro fertilization to ensure the presence or absence of particular genes or characteristics.” (Oxford University, 2005) Breeders of animals and plants

asddsaProteins (/ˈproʊˌtiːnz/ or /ˈproʊti.ɨnz/) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and
