What process involves antibodies cross-linking cells or particles into large aggregates?
The process is called agglutination. It occurs when antibodies bind to specific antigens on the surface of cells or particles, causing them to clump together or aggregate. Agglutination is commonly used in laboratory tests to detect the presence of specific antigens or antibodies.
What is direct immunoflorescence?
Direct immunofluorescence is a technique used in pathology to detect the presence of specific antibodies or antigens in tissue samples. It involves labeling antibodies or antigens with fluorescent dyes to allow visualization under a microscope. This technique is particularly useful in diagnosing autoimmune diseases and dermatological conditions.
What is neutralizing antigen?
Its the antigen in a particular foreign body or pathogen that the body recognizes as "allo" or unfamiliar.. Maybe even harmful. So antibodies are produced against these antigens. And since they are 'neutralizing antibodies' it follows that the antigens they bind to are 'neutralizing antigens'
A method of tagging antibodies with a fluorescent dye to detect or localize antigen-antibody combinations is known as?
Immunofluorescence staining. This technique involves binding a fluorescent dye to antibodies, which can then be used to detect and visualize specific antigens in a sample.
What does humoral immunity involves?
The cells which are involved in the production of antibodies are known as B cells. These are effector cells which will secrete anybodies and activate the antigens.
A test used to detect anti-Rickettsia antibodies in a patient is the?
Indirect immunofluorescence assay (IFA) is commonly used to detect anti-Rickettsia antibodies in a patient. This test involves exposing the patient's serum to Rickettsia antigens and then using fluorescently labeled antibodies to detect any bound antibodies. Positive results indicate a past or current infection with Rickettsia bacteria.
What is a difference between passive and active agglutination?
The only difference between the two is with active agglutination you have a particulate Ag + Ab, since the Ag is particulate, large, when a complex is formed it is visable. In passive agglutination the Ag is soluble so it must first be attached to something like latex beeds or a carrier so when agglutination occurs it can be seen with the naked eye.
When an antigen enters antibodies are produced but when a spermforeign particleenters a female why antibodies are not produced?
yours logic is right but here the sperms are not at all considered as antigens see friend whats the meaning for antigen? a foreign paticle which able to generate antibodies is nothing but antigen. here sperm doesn,t involves in antigen-antibody complex because of the lack of antibodys.
What is reverse agglutination?
Reverse agglutination is a technique used in laboratory diagnostics to detect specific antigens. It involves attaching antigens to latex beads, which will bind to antibodies present in a patient sample, causing visible clumping. This is a rapid and sensitive method for identifying the presence of certain pathogens or substances in a sample.
Which immune response involves antibodies?
Specific response
A function of the blood that involves circulating antibodies to combat infection?
One of the function of the blood is to circulate antibodies to combat infection.
What type of vaccine involves host synthesis of viral antigens?
A nucleic acid vaccine
