An antibody is identical to the B-cell receptor of the cell that secretes it except for a small portion of the C-terminus of the … Continue reading The Antibody
This article will review basic immunology principles by defining key terms and explaining different techniques and phenomenons. Key Definitions Sensitization is the basic reaction of an antigen and an antibody binding. During an antigen:antibody reaction, the antigen or the antibody can be measured using a variety of methods. Each method has its advantages and disadvantages. … Continue reading The Precipitation Curve

For more information on those two systems as a whole, review part one of the immune system. This part of the immune system … Continue reading Cells Cells Cells!
Protein electrophoresis measures the specific proteins in the body by using electrical charge to separate them. Serum proteins are either albumin or they are globulins. Globulins are then further delegated into either gamma globulins or alpha-1, alpha-2, or beta globulins. The normal ranges for each protein fraction in the serum is as follows; Albumin: 3.6-5.2 … Continue reading Serum Protein Electrophoresis (SPE)
Viral hepatitis is acute or chronic symptomatic or even sometimes asymptomatic inflammation of the liver. Usually the infection is self-limiting and clears within 12 weeks, but in immunocompromised patients it can pose serious complications and development of systemic problems. All viral hepatitities can lead to liver cirrhosis if untreated. There are important serological markers involving … Continue reading Viral Hepatitis
