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.
Oh ya! But if you donât quantify your Western blots correctly youâll find yourself in an unpleasant, unrepeatable and totally meaningless place. And while some scientists are okay dwelling in a meaningless place, I hope you are not. Review these important concepts about how to correctly quantitate your next Western blot. 1. Find the Linear Range. For quantitate analysis of an image you must ensure your image was captured in a manner sensitive enough to detect change, in what we call the âlinear rangeâ.
