All globulins fall into one of the following three categories : Alpha globulins; Beta globulins; Gamma globulins (one group of gamma globulins is the immunoglobulins, which are also known as "antibodies") Globulins can be distinguished from one another using serum protein electrophoresis. Globulins exert oncotic pressure. Their deficiency ...
Gamma globulin injections are usually given in an attempt to temporarily boost a patient's immunity against disease. Injections are most commonly used on patients having been exposed to hepatitis A or measles, or to make a kidney donor and a recipient compatible regardless of blood type or tissue match.
Fibrinogen from plasma samples will be seen in the beta gamma region. Fibrinogen, a beta-2 protein, is found in normal plasma but absent in normal serum. Occasionally, blood drawn from heparinized patients does not fully clot, resulting in a visible fibrinogen band between the beta and gamma globulins. [citation needed]
Contrary to popular belief, haemoglobin is not a blood protein, as it is carried within red blood cells, rather than in the blood serum. Serum albumin accounts for 55% of blood proteins, [1] is a major contributor to maintaining the oncotic pressure of plasma and assists, as a carrier, in the transport of lipids and steroid hormones.
Alpha-1 and Alpha-2 globulins are formed in the liver and play an important role in mineral transport and the inhibition of blood coagulation. [14] An example of beta globulin found in blood plasma includes low-density lipoproteins (LDL) which are responsible for transporting fat to the cells for steroid and membrane synthesis. [15]
These gamma globins bind to form hemoglobin Barts. [1] It is produced in the disease alpha-thalassemia and in the most severe of cases, it is the only form of hemoglobin in circulation. In this situation, a fetus will develop hydrops fetalis and normally die before or shortly after birth, unless intrauterine blood transfusion is performed. [2]
In inflammatory conditions, fibrinogen, other clotting proteins, and alpha globulin are positively charged, thus increasing the ESR. [9] ESR begins to rise at 24 to 48 hours after the onset of acute self-limited inflammation, decreases slowly as inflammation resolves, and can take weeks to months to return to normal levels.
All plasma proteins except Gamma-globulins are synthesised in the liver. [1] Human serum albumin, osmolyte and carrier protein; α-fetoprotein, the fetal counterpart of serum albumin; Soluble plasma fibronectin, forming a blood clot that stops bleeding; C-reactive protein, opsonin on microbes, [2] acute phase protein; Various other globulins
