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 blot tests take only one day to perform, but some laboratories may not run the test every day. Results from rapid tests done in the doctor's office or at other points of care are usually available in 15-20 minutes. If the rapid test is positive, it is still necessary to send blood to a laboratory for a Western blot to be sure the rapid test result is correct. Home tests are mailed to a laboratory, and results return in one to two weeks. RNA testing results usually take a few days to a week, depending on the lab.
