FAQ
What is sodium chloride used for in molecular biology?
Sodium chloride is commonly used in molecular biology procedures, such as DNA extraction, protein precipitation, and as a component in multiple buffers and media.
How is sodium chloride typically used in DNA extraction?
In DNA extraction, sodium chloride is often used in combination with other components to precipitate DNA from solution, allowing for separation from other cellular components.
What role does sodium chloride play in protein precipitation?
Sodium chloride is often used to precipitate proteins out of solution, allowing for easy isolation and purification of the proteins of interest.
What are some common buffers and media that contain sodium chloride?
Sodium chloride is a common component in buffers such as phosphate-buffered saline (PBS) and Tris-buffered saline (TBS), as well as in cell culture media and bacterial growth media.
Are there any precautions to be aware of when working with sodium chloride in molecular biology?
Users should be aware of the corrosive nature of sodium chloride and take proper precautions to avoid contact with skin and eyes. Additionally, sodium chloride should be stored in a dry environment to prevent clumping and contamination.
