Antisera is produced by injecting an animal (such as horses, rabbits, or goats) with specific antigens. The animal's immune system responds by producing antibodies against those antigens. The blood containing the desired antibodies is then collected and processed to obtain antisera, which contains a high concentration of specific antibodies for use in diagnostic or therapeutic applications.

Why antisera AB is colourless?
Antisera AB is often colorless because it lacks pigment-producing compounds. It is designed this way to prevent interference with colorimetric assays or reactions that rely on changes in color to detect the presence of specific antibodies or antigens. The absence of color makes it easier to accurately interpret results during laboratory testing.
What are the three main types of blood cells and special liquid?
The three main types of blood cells are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). The special liquid that makes up blood is called plasma, which carries the blood cells, nutrients, hormones, and waste products through the body.
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 are some practical applications of Quellung Reaction?
Quellung reaction is commonly used in microbiology for identifying and classifying specific bacteria based on their capsule thickness. It is also used in clinical settings to diagnose bacterial infections and in vaccine development to understand the variability of capsules. Furthermore, it can be applied in veterinary medicine for disease diagnosis in animals caused by encapsulated bacteria.
What the cell made up of muscles?
cell made a group and made a tissue and tissue together and made a musle
Does antiserum A when added to type O blood make blood clot?
No. Type O blood does not have the surface antigen that Type A antisera binds to. Only type A blood will clot when type A antisera is added.
Will type A blood react with anti-A antisera?
No because type A blood has antibody for B

How do you do blood group in autoagglutination?
Instead of using antisera for blood grouping , pooled known RBCs are used. the process is serum typing.so serum of patient whose Rbcs are auto aggluting is used.
Why is anti-sera A blue in color?
Anti-sera A can be blue in color due to the presence of certain dye molecules or other colorants that are added during the production process to help with identification and visualization of the anti-sera. Blue coloration does not impact the functionality or effectiveness of the anti-sera.
Why are horses used for antisera production?
Since horses are such big animals they can produce more antibodies and are more cost effective. And I have never seen a regular sized saddle horse. The companies that do this use draft horses, because once again, the animals are quite large.
Why is aN ANTI tetanus vaccination given?
Antisera is given to patients because it contains specific antibodies to the tetanus toxin. By binding, antibody to toxin, the toxin is neutralized. Otherwise, the toxin will cause tetanic musscle contractions seen in patients. This antisera causes a much faster response than the toxoid that is used as a vaccination. In this senario, a innactive form of the tetanus toxin (which is a toxoid) is introduced to healthy individuals. This toxoid causes the body (specifically B-cells) to produce antibodies and most importantly memory cells. Individuals who have circulating levels of antibody are considered immune to tetanus because the body will combat the pathogen before it has a chance to produce toxins.

Difference between anti sera and serum?
Antisera is blood serum containing antibodies against a specific antigen, used to treat or provide immunity to a disease. It is extracted from an animal that has immunity to a particular disease. Serum is the fluid obtained when whole blood is separated into its solid and liquid components after it has been allowed to clot. It is clear and yellow in color.
Why is anti sera B yellow in color?
Anti-sera B is yellow in color due to the presence of phenol red, a pH indicator that turns yellow in acidic conditions. This allows for visual detection of acid production in the presence of bacteria that utilize lactose as a carbon source.
