Hanks’ well balanced salt solution (HBSS) and phosphate buffered saline (PBS) are two types of salt solutions usually used for the upkeep of osmolality and pH in mobile culture applications. However, the formulations of both of these solution types differ. Though PBS is an easy solution containing phosphate buffer, HBSS is more complex and contains sodium bicarbonate.
This benefits from The point that the second and third terms turn into negligible at pretty reduced pH. This phrase is impartial with the existence or absence of a buffering agent.
