Using Direct Fluorescent Antibody Technique to Test for Chlamydia 1. Describe the importance of the washing steps in the direct antibody fluorescence test. It’s very important for the washing steps in the direct antibody fluorescence test to decrease the no-specific binding. 2. Explain where the epitope (antigenic determinant) is located. The epitopes are located in the antigens for the antibodies binding. 3. Describe how a positive result is detected in this serological test. The elementary

Intracellular free calcium levels: Intracellular free calcium levels were estimated according to the method of Luo and Shi (Luo and Shi‚ 2005). Briefly‚ hippocampi were isolated from mice brains and subjected to hippocampal cells isolation as described later. The cells obtained were incubated with Fura-2 AM at 37°C with gentle shaking. The fura-2 loaded suspension was centrifuged for 10 minutes‚ pellet was washed once with Ca2+-free buffer and was centrifuged again. Aliquots of the washed suspension

Anti-NMDA receptor encephalitis is a disease where antibodies produced by the body’s own immune system attack the NMDA receptors in the brain. What NMDA receptors are? NMDA receptors are electrical impulse controllers in the brain. Their function result in all autonomic functions such as; judgment‚ perception of reality‚ human interaction‚ the formation and retrieval of memory‚ and the control of unconscious activities What encephalitis does? Antibodies are an important part of the body’s defense

Lindsay Turner 4/20/01 White Blood Cells Bacteria exist everywhere in the environment and have continuous access to the body through the mouth‚ nose and pores of skin. Further more‚ many cells age and die daily and their remains must be removed‚ this is where the white blood cell plays its role. According to this quotation‚ without white blood cells‚ also known as leukocytes‚ we would not be able to survive. White blood cells are our body ’s number one defense against infections. They

antigens (HLA) occurs (Fuggle & Martin‚ 2008). This article shows that 23% of renal patients that are awaiting transplantation are sensitized. More females than males have the HLA antigen. It also shows that first time transplants have less HLA antibodies than those that have had transplants in the past. Several approaches to transplant sensitized patients are presently used or have been used in the past. It is important to understand the different techniques but knowing why is just as important

They recognise the same protein that activated T cells. B cells produce antibodies that are the same as T cell receptors as they precisely recognise the protein belonging to the pathogen. The antibodies are then released from the B cells into the blood. They will then meet the pathogen and attach themselves onto it. Killer T cells activate as well if the pathogen is a virus. This enables

animal is born with one’s innate resistance against certain pathogen. At present‚ all immune systems require contact with antigens‚ and they acquire immunity accordingly‚ which is viewed as an outdated concept. There are three possible cases : 1.The antibodies of the parent are transmitted to their fetus through the placenta or colostrum‚ and the infant is also referred to as a passive immunity. 2.A pathogen that is toxic to other species of animals is harmless to any animal‚ for example‚ a human distemper

Human bloods have differences precisely to the presence or absence of certain protein molecules called antigens and antibodies. The antigens can be found on the surface of red blood cells and the antibodies are in the blood plasma. Individuals have different types and combination of these molecules. Blood group is like a trait which we inherit to our parents. The blood group you belong depends on what you have inherited from your parents. There are three types of antigens: A antigen‚ B antigen
