Explain the antibody reactions of agglutination?

Explain the antibody reactions of agglutination?

Antibody tests: Latex beads are coated with an antigen. You you have antibodies against that antigen, your serum may agglutinate the beads. A titer can be determined by diluting the serum. Sometimes, a high titer may not agglutinate until the serum is diluted (prozone effect). ...Read more

Antigen (Definition)

Antigens are chemicals which upon exposure to the surface or inside of the body, will cause a reaction term allergic. Many substances will do this and allergic response is the basis for immunological protection for ...Read more

What makes immune cells only attack one type of antigen, as opposed to multiple different antigens?

What makes immune cells only attack one type of antigen, as opposed to multiple different antigens?

It's complicated: When immune cells come into contact with a foreign substance (called an antigen), they engulf that substance and either start making antibodies to it or activate other immune cells to come into the area to fight off the foreign invader. Antigens are fairly specific so antibodies that form are also fairly specific. Sometimes mistakes occur however. Here's a link to more: http://bit.ly/1uy9lyG ...Read more

Does complement affect IgG and IgM reactions with antigens?

Does complement affect IgG and IgM reactions with antigens?

Complement: Complement is a serum protein that works with IgM and some igg subtypes to destroy foreign invaders. Persons with complement deficiency can have an increased frequency of infections. ...Read more

Does a monoclonal antibody reactive with the o139 antigen of e.Coli would cross react with v.Cholera o139?

Apparently not.: This does not seem likely because first that the v cholera is usually found in india and bangladesh while ecoli is usually in the U.S., mexico, and south america. Second, the mechanisms are different because the genes for toxicity on the e coli strains are not present in the v cholera. Third, there seems to be no information on any cross reaction of these two o 139 strains. ...Read more

Does HIV DNA PCR have different assays for the strains of hiv1 and hiv2?

Does HIV DNA PCR have different assays for the strains of hiv1 and hiv2?

Yes, but complicated: Trying to tell whether a person has HIV-1, HIV-2, or both, can get complicated. If a person has high risk exposures or has symptoms, he can see an HIV Infectious Disease doctor and trust the advice, but follow-up as instructed. There are many different tests (usually by various manufacturers) in different parts of the world, which happen to have different prevalences for various HIV strains. ...Read more

What type of antibody is associated with ABO group types?

What type of antibody is associated with ABO group types?

ABO blood groups: Not sure i understand your question. Abo antigens are glycoproteins (sugar-like molecules) found on the surface of red cells. There are 4 common types: groups a, b, ab, and o. People with type a blood have antibodies against b. Those with type b have antibodies against a. Those with type ab don't have any antibodies at all, while those with type o have antibodies against both a and b. ...Read more

Hi Doctor, I did blood testing of Liver. the result are Anitibody anti HBe or Aniticorp anti HBe : Reaction Positive & Antigene HBe Reaction Negative.

Hepatitis B tests: An antibody means that your body reacted to something and tried to fight it off. That's your immune system doing what it's supposed to. An antigen is something like a piece of virus that shouldn't be there. Your test report shows you were exposed to Hepatitis B but luckily your body fought it off. This HepBe test helps prove if you developed immunity from natural infection or from the vaccine. ...Read more

Describe polyclonal and monoclonal antibody production?

Cells vs, animals: A monoclonal antibody is produced by in-vitro manipulation by expoanding a single cell making a desired antibody. Polyclonal antibodies are usually derived from immunizing an animal and colletcting its blood/serum containing the antibody. Polyclonal antibodies are a mixture of a large number of different cells. ...Read more

How CRP (c-reactive protein) can be marker of the immune system?

How CRP (c-reactive protein) can be marker of the immune system?

Marker of : Inflammation. Elevated CRP is an indicator of inflammation, including that due to infections. It is one of the acute phase reactants. It helps in clearing some of the microbes. High sensitivity CRP test is used to assess risk of cardiac disease. ...Read more

Are hypersensitivity reactions are caused by the cross linking of antibodies?

Are hypersensitivity reactions are caused by the cross linking of antibodies?

On the cell surface.: Ige mediated allergic reactions involve 2 ige antibodies directed against the same allergens in close proximetry on the surface of mast cells or basophils. The antibody then fits in between the 2 ige antibodies. That activates the cell to release mediators (chemicals) that directly or indirectly by activating other cells resulting in allergy symptoms. The ige antibodies themselves do'nt cross link. ...Read more

Does ELISA HIV test detect type o or other type of hiv?

Does ELISA HIV test detect type o or other type of hiv?

HIV screening: An ELISA is often done as an initial HIV screening test. It is designed to have high sensitivity for most types of HIV in the gene real population, but does have some false positives. That being said, there are some types of HIV, e.g. type O, that are unusual outside of Cameroon or West Africa, but are not recognized by usual antibody tests. Check with an I.D. specialist for your area and test. ...Read more

Immunifixation identifies m spike as IGg Kappa polyclonal gamma globulin to consist mainly of IGg Kappa n Lamda with fair amounts of Iga means what?

Immunifixation identifies m spike as IGg Kappa polyclonal gamma globulin to consist mainly of IGg Kappa n Lamda with fair amounts of Iga means what?

?? Chronic Infection: M spike of polyclonal IgG (kappa & lambda) globulin mostly suggest chronic infectious or inflammatory process & rarely hematologic malignancies. You need a complete work up for ch. liver disease, hepatitis B/C, ch.bacterial, viral & fungal infection, HIV, autoimmune diseases & if negative then evaluate for hematological disorder.

What is hepatitis b surface antigen in general?

What is hepatitis b surface antigen in general?

Infection is active: If you are surface antigen postive = protein on the surface of the virus is in its active form which is still floating in your blood and indicates active/on going infectious state. This protein triggers body to produce antibody which can help rid off the infection or preventing it as in case of hepb vaccines. In your case, no antibody or not enough to rid of the antigen. Consult doc. Good luck. ...Read more

What are antigens and antibodies, in relation to hepatitis?

Hepatitis AG & AB: The most common forms are hepa, hepb, and hepc. When testing for these forms you will do a blood test that will show antigens (ag) and/or antibodies (ab) for hepatitis. Hepa and hepc only have one ag which will result in one ab to fight if off. Hepb has both a surface ag (hbsag) and e ag (hbeag) resulting in hbsab, hbeab and hbcab (with results from infection of hepb). ...Read more
