1 Slate can start as low as $1-$3 a square foot for basic floor tiles. 2  Depending on size, finish, thickness and color, higher quality slate tiles can cost $4-$10 a square foot, while mosaics and other specialty tiles (usually used as accents) can be $8-$35 a square foot for just the tiles. Slate sealer costs $10-$30 a gallon. 2  For a shiny or matte finish or if the slate is relatively porous (tending to stain), the slate should be sealed before and after installation, and then every one to two years, depending on the amount of traffic and wear on the floor.
Save. Amylase and lipase are digestive enzymes produced by the pancreas. Amylase and lipase tests are used to distinguish acute appendicitis from acute pancreatitis. Both tests are done on blood, but amylase may also be tested from a urine sample.
A lipase is any enzyme that catalyzes the hydrolysis of fats. Lipases are a subclass of the esterases. Lipases perform essential roles in the digestion, transport and processing of dietary lipids in most, if not all, living organisms. Genes encoding lipases are even present in certain viruses. Most lipases act at a specific position on the glycerol backbone of a lipid substrate. For example, human pancreatic lipase, which is the main enzyme that breaks down dietary fats in the human digestive sy
