  2. Phosphate-buffered saline - Wikipedia

    en.wikipedia.org/wiki/Phosphate-buffered_saline

    There are many different ways to prepare PBS solutions, common ones are Dulbecco's phosphate-buffered saline (DPBS) [2] and the Cold Spring Harbor protocol. [3] Some formulations of DPBS do not contain potassium and magnesium, while other ones contain calcium and/or magnesium (depending on whether or not the buffer is used on live or fixed tissue: the latter does not require CaCl 2 or MgCl 2).

    "The pH of the 10x stock solution of PBS is ~6.8, but when diluted with water to 1x PBS it should change to 7.4." This line is incorrect, surely? Buffer pH is not dependent on ion concentration, it should stay the same at 10x dilution. The 10x stocks you can buy are all pH 7.4.

  4. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    The majority of biological samples that are used in research are kept in a buffer solution, often phosphate buffered saline (PBS) at pH 7.4. In industry, buffering agents are used in fermentation processes and in setting the correct conditions for dyes used in colouring fabrics. They are also used in chemical analysis [5] and calibration of pH ...

  6. Hanks' salts - Wikipedia

    en.wikipedia.org/wiki/Hanks'_salts

    Hanks' salts is a collective group of salts rich in bicarbonate ions, formulated in 1940 by the microbiologist John H. Hanks. [1] Typically, they are used as a buffer system in cell culture media and aid in maintaining the optimum physiological pH (roughly 7.0–7.4) for cellular growth.

    en.wikipedia.org/wiki/Miles_and_Misra_method

    Phosphate Buffered Saline (PBS) or other appropriate diluent. Bacterial suspension or homogenate. Method. The inoculum / suspension is serially diluted by adding 1x of suspension to 9x of diluent. When the quantity of bacteria is unknown, dilutions should be made to at least 10 −8.

  8. Ringer's solution - Wikipedia

    en.wikipedia.org/wiki/Ringer's_solution

    Ringer's solution typically contains sodium chloride, potassium chloride, calcium chloride and sodium bicarbonate, with the last used to buffer the pH. Other additions can include chemical fuel sources for cells, including ATP and dextrose , as well as antibiotics and antifungals.

  9. Lysis buffer - Wikipedia

    en.wikipedia.org/wiki/Lysis_buffer

    RIPA buffer is a commonly used lysis buffer for immunoprecipitation and general protein extraction from cells and tissues. The buffer can be stored without vanadate at 4 °C for up to 1 year. [10] RIPA buffer releases proteins from cells as well as disrupts most weak interactions between proteins. [9] Recipe: [10] 1% (w/w) Nonidet P-40 (NP-40)
