What else can I help you with?
Are anitgens proteins?
Yes. An antigen is a substance that stimulates an animal in order to produce an antibody reaction to counteract the substance by a specific binding antibody-antigen. Most of the times this antigen is a molecule of protein.
What type of protein helps identify foreign cells?
An antibody is a highly specific protein that attaches itself to a foreign substance.
What is a substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
What is the different between polyclonal antibody and antiserum?
polyclonal antobody is the antibody produced for many or non specific antigens but antiserum is the antibody for a specific antigen
What is a phatogen?
A substance that when introduced into the body stimulates the production of an antibody.
What does an active antibody look like?
An active antibody is a Y-shaped protein molecule that is produced by the immune system in response to the presence of a foreign substance (antigen) in the body. The two arms of the Y-shaped antibody can bind to specific antigens, marking them for destruction by other immune system cells.
What is a disease-fighting protein created by the immune system in response to the presence of a specific antigen?
Antibody - produced by B lymphocytes.
What is an antigen made of?
An antigen may be made of either a bacteria or a virus. An antigen refers to a toxic or a foreign substance that once in the body attracts and is bound to a respective and specific antibody.
What individual hypersensitivity to a substance usually antibody-antigen reaction is known as?
It is an allergy
How many types of antigens can bind to a single antibody?
An antibody can typically bind to one specific type of antigen.
An antigen stimulates B cells to produce a specific what?
An antigen stimulates B cells to produce a specific antibody. This antibody is capable of recognizing and binding to the antigen that stimulated its production, marking it for destruction by other components of the immune system.
Suppose a fixed number of joules of energy as heat is added to 1 kg of substances listed below. Which substance will the rise in temperature be the least?
The substance with the highest specific heat capacity will experience the smallest rise in temperature with the same amount of heat energy added. Water has the highest specific heat capacity among common substances, so it will experience the least rise in temperature when a fixed amount of energy is added.
