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.
PCR is short for polymerase chain reaction and is a method we can use to clone sequences of DNA. We often want to clone these sequences a whole bunch (on the order of a billion copies of a single sequence!), so technology is obviously involved. This is how it works: DNA is collected from somewhere.
