Commonly used buffer.
Save time and simplify your buffer preparation step by using concentrated Fisher BioReagents 10X PBS solution - simply dilute as needed.
10X solution contains 1.37M NaCl, 0.027M KCl and 0.119M phosphates.
pH of a 1X solution made from this concentrated solution is ∼7.4.
To prepare a 1X solution, mix one volume of Fisher BioReagents 10X PBS solution with 9 volumes of ultrapure water.
Filtered and tested for the absence of DNase, RNase, and protease.
PBS is used in many biochemical applications to maintain pH.
Intended for laboratory research use only.
