Because of the ability to reduce disulfide bonds, DTT can be used to denature CD38 on red blood cells. DTT will also denature antigens in the Kell, Lutheran, Dombrock, Cromer, Cartwright, LW and Knops blood group systems. Conversely, the solvent exposure of different disulfide bonds can be assayed by their rate of reduction in the presence of DTT.
Serum total protein, also known as total protein, is a clinical chemistry parameter representing the concentration of protein in serum. [1] Serum contains many proteins including serum albumin, a variety of globulins, and many others. While it is possible to analyze these proteins individually, total protein is a relatively quick and ...
The most commonly used methods for measuring drug concentration levels in the plasma measure bound as well as unbound fractions of the drug. The fraction unbound can be altered by a number of variables, such as the concentration of drug in the body, the amount and quality of plasma protein, and other drugs that bind to plasma proteins.
The epithelial DNA in solution is removed and saved, while the sperm cell's DNA precipitates with the attached protamines. Differential extraction uses a chemical called dithiothreitol (DTT) to disrupt the sulfur bonds in the protamines in order to release its DNA. Once the DNA is detached from the protamines, it is prone to standard DNA ...
Hypoproteinemia is a condition where there is an abnormally low level of protein in the blood. There are several causes that all result in edema once serum protein levels fall below a certain threshold.
For substances that exhibit substantial plasma protein binding, clearance is generally dependent on the total concentration (free + protein-bound) and not the free concentration. [ 9 ] Most plasma substances have primarily their free concentrations regulated, which thus remains the same, so extensive protein binding increases total plasma ...
Radioimmunoprecipitation assay buffer (RIPA buffer) is a lysis buffer used to lyse cells and tissue for the radio immunoprecipitation assay (RIPA). [1] [2] This buffer is more denaturing than NP-40 or Triton X-100 because it contains the ionic detergents SDS and sodium deoxycholate as active constituents and is particularly useful for disruption of nuclear membranes in the preparation of ...
Despite its low concentration, TBG carries the majority of T 4 in the blood plasma. Due to the very low concentration of T 4 and T 3 in the blood, TBG is rarely more than 25% saturated with its ligand. Unlike transthyretin and albumin, TBG has a single binding site for T 4 /T 3. TBG is synthesized primarily in the liver as a 54-kDa protein.
