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 ...
An example of nutritional hypoproteinemia is Kwashiorkor, a type of protein energy malnutrition affecting young children. Malabsorption , often caused by celiac disease or inflammatory bowel disease Liver disease can also cause hypoproteinemia by decreasing synthesis of plasma proteins like albumin.
The kell protein is tightly bound to a second protein, XK, by a disulfide bond. Absence of the XK protein (such as through genetic deletion or through a single point mutation within the coding region of the XK gene [ 7 ] ), leads to marked reduction of the Kell antigens on the red blood cell surface.
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 ...
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.
Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine. Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury .
The protein CD55 (also called decay-accelerating factor) helps to regulate the complement cascade, part of the innate immune system, by regulating the amplification phase. When CD55 is absent, the complement system attacks red blood cells and causes them to be destroyed (hemolysis). [3] [4] [5]
