Answer to Question #110715 in Molecular Biology for FRIDAY

Question

Question 7: If you have excess reagent on the weighing boat, what should you avoid doing and why?

Answer 1

If you have excess reagent on the weighing boat you should avoid putting back an excess of the reagent into the stock. This may lead to the contamination of the stock powder with other reagents present on the weighting boat. This may change the properties of the reagent if further used. For example, if the stock is contaminated, the pH or ionic strength of the solution will be modified that may lead to a significant error.
