Lectins are glycoproteins of 60,000-100,000 MW that are known for their ability to agglutinate (clump) erythrocytes in vitro. There are over 400,000 estimated binding sites for kidney bean agglutinin on the surface of each erythrocytes. Lectins are found in most types of beans, including soybeans.
A DNA sequencer is a scientific instrument used to automate the DNA sequencing process.Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine).This is then reported as a text string, called a read.NA sequencer manufacturers use a number of different methods to detect which DNA bases are present. The specific protocols applied in different sequencing platforms have an impact in the final data that is generated. Therefore, comparing data quality and cost across different technologies can be a daunting task.
What is DNA sequencing? Sequencing DNA means determining the order of the four chemical building blocks - called bases - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off. In addition, and importantly, sequence data can highlight changes in a gene that may cause disease.
