<p>Disaccharide is a carbohydrate with two simple sugars. It is soluble in water and has a density of 1.621 g/ml. Disaccharides are found in the tissues of many plants and animals, where they can be hydrolyzed by various enzymes to release monosaccharides. Disaccharides are also found in certain types of lichen and algae, where they are produced through photosynthesis. The most common disaccharides are sucrose, lactose, maltose, trehalose, and cellobiose. The simplest type of disaccharide is called a monosaccharide or sugar molecule. Monosaccarides have the same chemical formula but different physical forms that depend on their molecular mass (i.e., they may be a solid or liquid). Disaccharides can be classified as either sulfuric or organic solvent-soluble depending on whether they dissolve in sulfuric acid or an organic solvent such as ethanol or</p>

<p>4-Aminobutyl 1,3-a-1,6-a-D-mannotriose is a custom synthesis that belongs to the category of oligosaccharides and polysaccharides. It is an aminotriose with a methyl group at the C4 position. The fluorinated glucose moiety and the 4-aminobutylic acid residue are in an alpha configuration. This oligosaccharide has been modified by click chemistry and features high purity. The modification was carried out by condensing the sugar with a boronic acid and then reacting this with an azide group. The resulting product is then reacted with a maleimide to create a conjugate that can be used in bioconjugation reactions.</p>

<p>The blood group antigen Sialyl Lewis X (SLeX) is an oligosaccharide which plays a vital role in cell-cell recognition processes. SLeX is a terminal residue on glycolipids that are present on the surface of white blood cells and plays a key role in inflamation processes (Collins, 2006). The inital adhesion of white blood cells to a site of injury is mediated by E-selectins which specifically interact with SLeX. Cell-cell recognition between leukocytes and endothelial cells in blood is believed to occur in part through interactions between lectins and oligosaccharide ligands (Munro, 1992).</p>

<p>A-BSA is an antibody that competes with the blood group antigen for binding to erythrocytes. The A-BSA is immobilized on a microtitre plate and incubated with the blood group antigen and human blood group antiserum. The concentration of A-BSA in the solution is determined by measuring the enzyme-linked immunosorbent assay (ELISA) signal using a spectrophotometer. This measurement is used to determine the concentration of blood group antigen in the sample.</p>
