Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate , sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate .
PBS is a balanced saline solution that will be used to wash cells to maintain osmotic balance between internal and external environment of cell. From: Methods in Cell Biology, 2023
28 sty 2019 · PBS or phosphate-buffered saline is a buffer solution that is particularly valuable because it mimic the ion concentration, osmolarity, and pH of human body fluids. In other words, it's isotonic to human solutions, so it's less likely to cause cell damage, toxicity, or unwanted precipitation in biological, medical, or biochemical research.
Phosphate buffered saline (PBS) is a buffer solution commonly used in biological research. PBS is isotonic and non-toxic to cells. It is used in several applications of tissue culture, most notably for cell washing and trypsinization.
The project-based science (PBS) model is a project-oriented instructional design model from the Project-Based Science (PBS) project, an effort that began in 1991 at the University of Michigan School of Education.
Types of projects PBS projects can be defined based on their intended stu-dent outcome: u Problem-solving projects are designed to teach problem-solving and critical-thinking skills. u Process-skill projects help students acquire science-process skills such as the ability to pose a researchable question, identify and formulate a
Project-based science (PBS) is a reform-based pedagogy that emphasizes the students themselves constructing a usable or meaningful understanding (Ausubel, 1968) of the science they are learning, as opposed to memorizing decontextualized scientific facts.
