What are the differences between TBST and PBST solutions used in laboratory experiments?

TBST and PBST are both commonly used solutions in laboratory experiments, but they have different compositions. TBST contains Tris-buffered saline and Tween-20, while PBST contains Phosphate-buffered saline and Tween-20. These solutions are used for washing and blocking steps in experiments, with TBST being more commonly used in protein-related experiments and PBST being more commonly used in nucleic acid-related experiments.
