The theory goes that these weren't normal rocks but rather the equivalent of cosmic sponges, loaded with water that was released on impact. While astronomers have confirmed that some asteroids and comets hold water, some scientists think the theory doesn't.
Western blot using an antibody that recognizes proteins modified with lipoic acid. The western blot (sometimes called the protein immunoblot) is a widely used analytical technique used to detect specific proteins in a sample of tissue homogenate or extract.It uses gel electrophoresis to separate native proteins by 3-D structure or denatured proteins by the length of the polypeptide.he name western blot was given to the technique by W. Neal Burnette and is a play on the name Southern blot, a technique for DNA detection developed earlier by Edwin Southern.
Results from a Western blot test are usually reported in terms of titers which is a measure of the amount of dilution a sample needs before no antibodies remain detectable. A high titer means, therefore, a high level of antibodies and is likely to indicate a major response by the body to a current or recent infection.he Western blot test for Lyme disease is usually used following a positive or indeterminate ELISA (or IFA) test which is more sensitive, but less specific, than the Western blot.
