strain of transgenic rnice capable of producing antibodies potentially useful in the treatment of human disorders including cancer‚ transplant rejectiory and inflammation. The idea of using rnice to produce antibodies for treating human diseases dated back to the 1970s; but only recently had therapies based on this approach passed the rigorous safety and efficacy tests necessary for regulatory approval. Many industry observers were now predicting an "antibody wave" as genornics research identified thousands

Humoral immunity From Wikipedia‚ the free encyclopedia Humoral immunity (also called the antibody-mediated system) is the aspect of immunity that is mediated by macromolecules (as opposed to cell-mediated immunity) found in extracellular fluids such as secreted antibodies‚ complement proteins and certain antimicrobial peptides. Humoral immunity is so named because it involves substances found in the humours‚ or body fluids. The study of the molecular and cellular components that comprise

maternal blood can stimulate the mother’s immune system to produce anti-Rh antibodies. The anti-Rh antibodies are not produced in significant amounts until after delivery‚ therefore‚ a woman’s first infant is not affected. During the following pregnancies‚ when fetal and maternal circulatory systems are closely intertwined‚ the mother’s antibodies may cross the placenta. Hemolytic anemia can form when the mother’s antibodies enter the fetal circulatory system. Rh incompatibility is almost completely

The Lymphatic System And Immunity The cells‚ tissues‚ and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens‚ or disease-causing organisms. Acts against environment hazards‚ various pathogens‚ and internal threats. Lymphocytes (primary cell) are vital to or overcoming infection and disease. Lymphocytes respond to invading pathogens‚ abnormal body cells‚ and foreign proteins. They act to eliminate these threats or render them harmless

LYMPHATIC SYSTEM * Carries fluid in one direction‚ from the tissues to the circulatory system. Functions of the Lymphatic System 1. Fluid Balance * Collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream. 2. Fat Absorption * Absorbs fats and other substance from the digestive tract through lymphatic vessels called lacteals located in the lining of the small intestine. * Fat enters the lacteals and pass through the lymphatic vessels

Once on the membrane‚ it must be blocked using skim milk and treated with a primary and secondary antibody in order to identify a specific protein.

After conducting the experiment I was able to identify each patients blood type by comparing the antigens and antibodies found within the blood. Materials and Methods Simulated blood‚ plastic slides‚ and antiserum were the materials used to perform this experiment. In order to specify each patients blood type it was necessary to place two drops of the simulated
