pH = pKa + log ( [A-]/ [HA]) Proton hopping. short "hops" of protons between a series of hydrogen-bonded water molecules result in an extremely rapid net movement of a proton over a long distance. As a hydronium ion gives up a proton, a water molecule some distance away acquires one, becoming a hydronium ion. Proton hopping is much faster than ...

Paired helical filaments (PHFs) are prominent components of Alzheimer disease (AD) neurofibrillary tangles (NFTs). Rather than isolating NFTs, we selected for PHF populations that can be extracted from AD brain homogenates. About 50% of PHF immunoreactivity can be obtained in 27,200 x g supernatants following homogenization in buffers containing 0.8 M NaCl.

You determine a protein's mass as 500 kDa. You run a gel electrophoresis using SDS PAGE and observe four bands: 244, 133, 69, and 54. Using SDS PAGE with 2-mercaptoethanol, you again see 4 bands: 133, 122, 69 and 54. Determine size and number of subunits of protein and why you see different sizes using 2-mercaptoethanol.

Polyacrylamide is a hydrophilic, water-soluble polymer that can comprise nonionic, cationic, anionic, or zwitterionic charge.

Jan 12, 2022 · The word surfactant means surface active agent. As the name implies, surfactants stir up activity on the surface you are cleaning to help trap dirt and remove it from the surface. Surfactants have a hydrophobic (water-hating) tail and a hydrophilic (water-loving) head. The hydrophobic tail of each surfactant surrounds soils.

SDS-Polyacrylamide Gel Electrophoresis (PAGE) In their native form, proteins fold into a variety of shapes, some compact, some elongated. The rate of migration of native proteins through a sieving medium is therefore more a reflection of their relative compactness, and less an accurate measure of molecular weight.
