PBS stands for phosphate-buffered saline, it is a common buffer used in tissue work because its pH, ionic strength and osmolarity are close to that of animal tissue fluids and serum. When you do tissue work, or excise tissue from animal to test tube, you want to bath the tissue in similar fluid that the cells are in their native environment. If you'd use buffer with pH, ionic strength or osmolarity very different from the tissue fluid, you'd risk tissue and cell damage, and hence destroying your sample. You can easily find the composition of PBS and animal tissue fluids by googling and compare them.
