PBS: phosphate-buffered saline
DPBS: Dulbecco's phosphate-buffered saline
They are balanced salt solutions used to maintain cell culture media in the physiological range of 7.2-7.6. Provides cells with water and certain bulk inorganic ions essential for normal cell metabolism. They are used in washing cells before dissociation, transporting cells or tissue, diluting cells for counting, and preparing reagents.
They can be used interchangeably, but dPBS is typically slightly lower in phosphate concentration and may include calcium and/or magnesium

EDTA (ethylenediaminetetraacetic acid): A chelating agent. A chemical that binds certain metal ions, such as calcium, magnesium, lead, and iron. In experiment, EDTA helps to stop DNases from acting on the exposed DNA. In molecular biology applications, it is used to minimize metal ion contamination and prevent enzymatic activity.
EGTA(ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid), also known as egtazic acid: an aminopolycarboxylic acid, a chelating agent. Compared to EDTA, it has a lower affinity for magnesium, making it more selective for calcium ions. It is useful in buffer solutions that resemble the environment in living cells where calcium ions are usually at least a thousandfold less concentrated than magnesium.
