Size zero Size zero Size zero or size 0 is a women's clothing size in the US catalog sizes system. Size 0 and 00 were invented due to the changing of clothing sizes over time (referred to as vanity sizing or size inflation), which has caused the adoption of lower numbers. For example, a 2011 size 0 is equivalent to a 2001 size 2, and is larger than a 1970 size 6 or 1958 size 8. Modern size 0 clothing, depending on brand and style, fits measurements of chest-stomach-hips from 30-22-32 inches (76-56-81 cm) to 36-28-36 inches (90-71½-90 cm). Size 00 can
Molecular-weight size marker a fluorophore). This derivitization with a fluorophore permits both separation on a gel under the desired circumstances and fluorescence imaging of the gel. In this case, a polyacrylamide gel is used. As with DNA, RNA, and protein electrophoresis, markers are run alongside the samples of interest in carbohydrate gel electrophoresis. The markers consist of oligosaccharides of known molecular weight. Like the samples of interest, the marker is also derivitized with a fluorophore (usually with 8-aminonapthalene-1,3,6-trisulfonic acid (ANTS) or 2-aminoacridone). Molecular-weight size marker A molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a
