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.
This study demonstrates the performance and reliability of the Precision Plus Protein WesternC standards, Immun-Star WesternC chemiluminescent detection kit, and ChemiDoc XRS imaging system when used to estimate the MW and amount (in ng) of protein samples in a western blotting experiment.
