The Biuret reagent is commonly used in protein determination methods. Here are the correct statements about the Biuret reagent:

1. It contains Cu2+ ions - True. The Biuret reagent contains copper ions in a solution of sodium potassium tartrate and sodium hydroxide. The copper ions react with peptide bonds (linkages between amino acids in proteins) to produce a color change.

2. It can be used to measure DNA concentration - False. The Biuret reagent is not used to measure DNA concentration. It is used to measure protein concentration. For DNA concentration, other methods like spectrophotometry or fluorescent dye binding assays are used.

3. The solution is alkaline - True. The Biuret reagent is alkaline because it contains sodium hydroxide. The alkaline conditions are necessary for the reaction with protein to occur.

4. It contains biuret - False. Despite its name, the Biuret reagent does not actually contain biuret. The name comes from the fact that biuret, a compound with two peptide-like bonds, gives a positive reaction with the reagent.
