antigens and antibodies

The foreign matter that enters the body and elicits a specific immune response by lymphocytes is an antigen (anti - antibody gen - generating) It stimulates the immune system to produce protective chemicals or special cells to destroy the antigens. These protective che..

An antigen is any chemical substance that, when introduced into the body, causes the body to produce specific antibodies, which can react with the antigen. Chemically a vast majority of antigens are proteins , nucleoproteins, lipo proteins etc. The entire bac..

Monoclonal antibodies are pure, high affinity, antigen specific, proteinaceous bodies derived outside the organism from clonal cultures of hybrid cells called hybridoma..

An antibody is a protein produced by the body in response to the presence of an antigen. Anti bodies belong to a group of proteins called globulins and they are also known as Immunoglobulins (Ig..

Monoclonal antibodies are pure, high affinity, antigen specific, proteinaceous bodies derived outside the organism from clonal cultures of hybrid cells called hybridomas. Being very specific and reproducible, antibodies are able to be conjugated to toxic drugs and inje..

Antibodies are proteins. Most antibodies contain 4 pairs of polypeptide chains. Two of the chains are identical to each other and are called Heavy chains or H chains and they are long chains. the other 2 chains, also identical to each other, are called Light or L chains and..

Organ transplantation is defined as the transfer of organs (like kidneys, heart liver etc) from one person to another. An organ transplant always involves a donor - who donates an organ and a recipient - who receives the organ. For an organ transplantation, the donor and the recipient should be gen..

, a German Biochemist, discovered the ABO blood grouping. ABO blood groups are determined by the gene I (for Isoagglutinin). There are 3 alleles, I A , I B and I o of this gene. Proteins produced by the I A and I B alleles are known as A and B antigens respectively. Individuals with ..

There are four types of blood among the humans. These are called the blood groups . The blood groups are classified based on the presence or absence of certain proteins and antibodies. In human blood, the membranes of the Red blood Corpuscle have certain proteins called the antige..

Antibodies that neutralize toxins produced in the body like bacterial toxins or introduced from outside like snake venom are called antitoxins. They are produced artificially these days. The antigen for e.g., snake venom is injected in low doses into an animal like horse or rab..
