Some globulins are produced in the liver, while others are made by the immune system. Globulins, albumins, and fibrinogen are the major blood proteins. The normal concentration of globulins in human blood is about 2.6-3.5 g/dL. The term "globulin" is sometimes used synonymously with "globular protein".
Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is applied to either an acetate membrane soaked in a liquid buffer, [3] or to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein ...
Fractions I, II, and III are precipitated out at earlier stages. The conditions of the earlier stages are 8% ethanol, pH 7.2, −3 °C, and 5.1% protein for Fraction I; 25% ethanol, pH of 6.9, −5 °C, and 3% protein. The albumin remains in the supernatant fraction during the solid/liquid separation under these conditions.
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. Higher drug concentrations would lead to a higher fraction unbound, because the plasma protein would be saturated with drug and any excess drug would ...
Blood plasma is the liquid component of whole blood, and makes up approximately 55% of the total blood volume.It is composed primarily of water with small amounts of minerals, salts, ions, nutrients, and proteins in solution.
Globulins make up 38% of blood proteins and transport ions, hormones, and lipids assisting in immune function. Fibrinogen comprises 7% of blood proteins; conversion of fibrinogen to insoluble fibrin is essential for blood clotting. The remainder of the plasma proteins (1%) are regulatory proteins, such as enzymes, proenzymes, and hormones.
Alpha globulins are a group of globular proteins in plasma [1] that are highly mobile in alkaline or electrically charged solutions. They inhibit certain blood proteases and show significant inhibitor activity. The alpha globulins typically have molecular weights of around 93 kDa.
All plasma proteins except Gamma-globulins are synthesised in the liver.
