What else can I help you with?
Which test involves placing samples of an unknown bacterium in saline adding different antisera and checking for clumping?
The test you are referring to is called the slide agglutination test. In this test, samples of an unknown bacterium are mixed with different types of antibodies (antisera) and observed under a microscope. If the antibodies react with the bacteria, clumps or aggregates will form, indicating a positive result.
What is the Name of the method to speed up sedimentation process?
The method used to speed up the sedimentation process is called "flocculation." This technique involves adding flocculants, which are chemicals that help small particles clump together into larger aggregates, or flocs. These larger particles settle more quickly due to their increased mass, thereby accelerating the sedimentation process. Flocculation is commonly used in water treatment and various industrial applications.
Which type of immunity involves natural transfer of readymade antibodies?
The type of immunity that involves the natural transfer of ready-made antibodies is called passive immunity. This occurs when antibodies are transferred from one individual to another, such as from mother to infant through breast milk or the placenta. Unlike active immunity, which develops through exposure to pathogens or vaccination, passive immunity provides immediate but temporary protection.
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.
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 the difference between aggregation and agglutination?
Aggregation involves clumping of platelets while agglutination involves clumping of particles in the presence of antibodies.

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.
How could an antibody cause a problem in a transplant?
Antibodies can cause rejection of the donor organ/ tissue within minutes if the person receiving the organ already had antibodies against the donor. Rejection of donated blood involves antibodies which form the basis of the immune response triggered by the donation. Rejection of a donated kindey or heart involves both antibodies and cell mediated immunity.
How are antibodies made in the lab?
Antibodies are made in the lab through a process called hybridoma technology. This involves fusing a specific type of immune cell with a cancer cell to create a hybrid cell that can produce antibodies. These antibodies can then be harvested and used for various purposes, such as in diagnostic tests or as treatments for diseases.
Digestion in lower animals is which involves food particles directly the cell?
Digestion in lower animals is _____ which involves food particles directly the cell
What part of matter does electricity involve?
Electricity involves charged particles. An electric current involves the movement of charged particles. These charged particles MAY be electrons, and often are; but it is possible to have an electric current with many other types of charged particles.

Which process involves antibodies covering surface receptors on a virus or toxin molecule thereby disrupting their activity?
Neutralization

What is passive and active in articifial immunity?
In artificial immunity, active immunity involves the introduction of antigens into the body, prompting the immune system to produce its own antibodies. This can occur through vaccination, leading to long-lasting protection. In contrast, passive immunity involves the direct transfer of antibodies from one individual to another, such as through intravenous immunoglobulin or maternal antibodies passed to an infant, providing immediate but temporary protection.
