Purpose of antibody screening
Antibodies are also called immunoglobulins which can be a largely y shaped proteins that function to spot and support to remove foreign antigens such as viruses & bacteria. Antibodies exist freely within the bloodstream or else are going to be bounded to the cell membranes, in other words these are said to be the part of the humoral immune system.
Monoclonal antibody is a laboratory produced molecule which is carefully engineered to attach to specific defects in cancer cells. NHL can be a serious affection which occurs because of the presence of B cells, a kind of white blood cells which cause severe complications like tumors. Monoclonal antibody was found safe and effective process for certain patients. This type of monoclonal antibody drugs are relatively a new innovation in cancer treatment and are identical because they are produced by one type of immune cell, all clones to a single parent.
Production of Monoclonal antibody:
• They're produced from only one cell line, for the assembly of monoclonal antibody a B lymphocyte can be fused with a tumor cell and this fused cell is known as hybridoma which has the capability of reproducing endlessly. By means of the help of this technology it is possible to produce unlimited and huge quantities of specific antibody that are used to treat diseases effectively.
Benefits of Monoclonal antibody:
• Absolute specificity
Uses:
• Monoclonal antibodies are going to be widely used as diagnostic & research reagents
The main goal of antibody screening is usually to detect unexpected clinically significant red cell antibodies. These kinds of antibodies are going to be called unexpected since only 0.3 to 2% of the overall population have positive antibody screen.
Phage display might be simply explained as practice of displaying peptides or proteins on the surface of bacteriophages. Phage display has been first explained by George P Smith in 1985. Phage display can be used for the choice of proteins, peptides or antibodies with affinity and specificity to some molecule or protein. It may also be helpful for preservation of unstable hybridoma clones & to identify molecules which may be recognized. The leading purpose of phase display is to see proteins that could interact with disease causing molecules using the intent of disarming this kind of molecules & curing otherwise weakening the disease.
Process of phage display consists of:
• Selecting binding entities by means of high affinity & high specificity to some target from the phase display libraries
• Producing and evaluating the selected binging entities to select therapeutic leads
Advantages of phage display:
• Diversity & abundance
• High speed and cost effective
• Automated parallel screening
• Rapid optimization
