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 .
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.
8 lip 2019 · PBS and dPBS are the abbreviations of phosphate-buffered saline and Dulbecco’s phosphate-buffered saline, respectively. They are well-known buffer solutions that are commonly employed in biological research to maintain a consistent pH (between 7.2-7.6).
21 wrz 2024 · The human body is the physical substance of the human organism. Characteristic of the vertebrate form, the human body has an internal skeleton with a backbone, and, as with the mammalian form, it has hair and mammary glands. Learn more about the composition, form, and physical adaptations of the human body.
3 lis 2023 · The human body is a biological machine made of body systems; groups of organs that work together to produce and sustain life. Sometimes we get lost while studying about cells and molecules and can’t see the forest for the trees.
But one fundamental aspect is the atoms making up your body. At the basic level, you are made of just four types of particles, which have been around for the majority of the lifetime of the Universe. In one sense this is very reductionist. You might rightly argue that you are far more than a collection of particles.
The human body is a complicated, highly organized structure that consists of trillions of parts that function together to achieve all the functions needed to maintain life. The biology of the human body incorporates: The body’s structure, the study of which is called anatomy.
