Title: Isolation and purification of bovine milk α-lactalbumin. Abstract: The Bradford assay‚ a colorimetric protein assay‚ is based on an absorbance shift of the dye Coomassie Brilliant Blue G-250 in which under acidic conditions the red form of the dye is converted into its bluer form to bind to the protein being assayed. The (bound) form of the dye has an absorption spectrum maximum historically held to be at 595 nm. Objective: To determine the technique to a series of protein purification

Planning Exercise Aim To investigate the effect of phosphate on cell division in root tips. Background knowledge Phosphate ions (macronutrients) are needed large amounts by plants. They are required for root growth. For the root tips cells to divide‚ mitosis has to occur. Phosphate is needed for production of ATP which provides energy for mitosis to occur. DNA replication occurs during interphase of the cell cycle. DNA is made up of nitrogen containing base‚ pentose sugar and phosphate group

The dichloromethane was dried with about 10g of anhydrous sodium sulphate for 10 minutes after which the sodium bicarbonate was filtered using the Büchner funnel. The mass of an evaporating dish was measured and the dichloromethane placed in the evaporating dish and placed on steam bath until it evaporated into a solid

Who is affected by hearing loss? Hearing loss is the most common physical disability in the whole wide world. In the United States alone‚ about 28 million people have some level of hearing impairment that interferes with their ability to understand normal speech and participate in conversations. Another 2 million cannot hear at all. Age is the most common factor in increasing hearing loss. About 30 percent of people between 65 and 74 experience some difficulty in hearing. That percentage and the
