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.
Western Blotting. Western blot analysis can detect one protein in a mixture of any number of proteins while giving you information about the size of the protein.It does not matter whether the protein has been synthesized in vivo or in vitro.ou will use this antibody as a probe to detect the protein of interest. Western blotting tells you how much protein has accumulated in cells. If you are interested in the rate of synthesis of a protein, Radio-Immune Precipitation (RIP) may be the best assay for you.
