PBS

PBS, or Phosphate-Buffered Saline, is a saltwater solution commonly used in biological and medical laboratories. It mimics the natural conditions of the body’s fluids, maintaining a stable pH and osmotic balance. This makes it ideal for rinsing cells, diluting substances, or transporting biological samples without damaging them. Essentially, PBS keeps cells and tissues alive and stable during experiments or procedures by providing a gentle, balanced environment similar to the body's internal fluids.
