  2. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...

  3. Condensation reaction - Wikipedia

    en.wikipedia.org/wiki/Condensation_reaction

    The reaction may otherwise involve the functional groups of the molecule, and is a versatile class of reactions that can occur in acidic or basic conditions or in the presence of a catalyst. This class of reactions is a vital part of life as it is essential to the formation of peptide bonds between amino acids and to the biosynthesis of fatty ...

  4. Henderson–Hasselbalch equation - Wikipedia

    en.wikipedia.org/wiki/Henderson–Hasselbalch...

    A simple buffer solution consists of a solution of an acid and a salt of the conjugate base of the acid. For example, the acid may be acetic acid and the salt may be sodium acetate . The Henderson–Hasselbalch equation relates the pH of a solution containing a mixture of the two components to the acid dissociation constant , K a of the acid ...

  6. DNA condensation - Wikipedia

    en.wikipedia.org/wiki/DNA_condensation

    Condensed DNA often has surprising properties, which one would not predict from classical concepts of dilute solutions. Therefore, DNA condensation in vitro serves as a model system for many processes of physics, biochemistry and biology. [2] In addition, DNA condensation has many potential applications in medicine and biotechnology. [1]

  7. TE buffer - Wikipedia

    en.wikipedia.org/wiki/TE_buffer

    TE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. "TE" is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg 2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.

  8. Phosphate-buffered saline - Wikipedia

    en.wikipedia.org/wiki/Phosphate-buffered_saline

    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. The buffer helps to maintain a constant pH.

  9. Condensation - Wikipedia

    en.wikipedia.org/wiki/Condensation

    Condensation forming in the low pressure zone above the wing of an aircraft due to adiabatic expansion. Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
