B-Cells and T-Cells

These specialized cells are a critical part of the bodies humoral immune system. They recognize foreign antigens or invaders and mount a quick response. B-cells act quickly by developing antibodies to the antigen epitopes. T-cells react based on what serological class they are in. If it is a CD8 T-cell, its cytotoxic and can quickly … Continue reading B-Cells and T-Cells

Enzyme-Linked Immunosorbent Assays (ELISA)

The first step in any ELISA assay is the immobilization of the antigen within the sample to the wall of the wells within a microtiter plate. These microtiter plates are usually 96-wells. This is by direct adsorption to the plates surface or by using a capture antibody. The capture antibody has to be specific to … Continue reading Enzyme-Linked Immunosorbent Assays (ELISA)

Vaccinations

Inoculation, or vaccination, is a critical method in preventing disease. Vaccination dates back to 1000 CE where the Chinese utilized smallpox inoculation to prevent a future occurrence of the disease (History of Vaccines, 2017). A well-known use of vaccination was performed in 1796 where Edward Jenner inoculated a 13 year- old boy with cowpox to … Continue reading Vaccinations

Erythropoietin (EPO)

The role of red blood cells is to carry oxygen. Just like anything in the body, this is tightly regulated by a mechanism that monitors whether or not there is adequate oxygen getting to tissues and other cells. Hypoxia is detected by the peritubular fibroblasts of the kidneys which causes erythropoietin (EPO) to be released. The EPO geneContinue reading Erythropoietin (EPO)

Donath-Landsteiner Antibodies

The history of the DL antibody goes back to the 1900's. It was one of the first recognized forms of immune mediated hemolysis and responsible for inducing Paroxysmal Cold Hemoglobinuria (PCH). PCH is a transient condition, meaning that it comes on when immunoglobulins (Antibodies) are formed in response to a viral, bacterial, or spirochete infection. … Continue reading Donath-Landsteiner Antibodies
