Immunological libraries are however constructed using antibody V genes from vaccinated donors or people with the virus [93]. Synthetic and semi-synthetic libraries constructed using synthetic DNA oligonucleotides where repertoire diversity lacks the natural processes of immune maturation.
How Do You Create An Immune System?
The phage human antibody library made with combining these songs as a composite protein. With a small bacteriophage protein (gene 3 protein) (10-12). Each resulting phage has an antibody protein active on its surface. And contains a gene that incorporates antibodies into the phage genome.
What Are Therapeutic Human Antibody Library?
Immune human antibody library biopharmaceuticals widely used in the treatment of cancer. And also immunity, and inflammatory diseases or in the delivery of drugs. To target antigen, most of which are monoclonal antibodies. The antibody treatment detects and binds to the antigen receptor to activate. And also inhibit a series of biological processes that inhibit the growth of cancer cells. Or activate the immune system. The mechanical action of action (MOA) between antibody treatment and a small drug molecule. Although both directed at the same antigen site. Compared to a small drug molecule, the antibody treatment. It has the characteristics of high affinity, high specificity. And low immunity, as it is actually a monoclonal antibody. Which can detect and bind to a unique epitope.

The original monoclonal antibody (mab) produced with combining myeloma cell with stem cells to detect hybridoma secreting mab. The original therapeutic antibody usually produced on the murine host, leading to a serious human mouse-like speech called a HAMA reaction, which also interfered with the effects of the treatment. Although, the shortcomings of the short-lived component, xenogenicity and limited function gradually improved with the development of genetic engineering, in vitro cell culture technology and in-depth understanding of the function of each antibody piece. Over the past four decades, the human immune system has made great strides in the field of immune engineering. Below is a timeline of important antibodies for medical engineering and prescription drugs representing biopharmaceuticals.
5 Types of Immune System, Each with a Different Function
There are 5 types of surviving regional antibodies (immunoglobulin) and according to these types, they are classified into IgG, IgM, IgA, IgD, and IgE. They are still distributed and work differently in the body.
IgG
IgG is a major human antibody library in the blood and has a strong binding effect on bacteria and toxins, and thus plays an important role in the immune system. It is the only isotype that can pass through the placenta, and IgG transmitted from the mother’s body to protect the newborn baby.
IgM
IgM is composed of five units of Y-shaped basic structures and is widely distributed in the blood. Produced for the first time in the pathogen attack by B cells, IgM plays an important role in the first defense of the immune system.
IgA
While in the bloodstream, IgA mainly found as monomers (a Y-shape), but it also makes dimers (a combination of 2 Ys) in secretions such as intestinal fluid, nasal secretions, and saliva, preventing bacterial invasion from mucus. membrane. It is also present in breast milk and protects the intestinal tract of newborns from bacterial and viral infections.
IgD
IgD is present in the surface of B cells and reported to play a role in initiating human antibody library production and preventing respiratory tract infections.
IgE
As per research that IgE originally associated with an immune response to parasites. By binding to mast cells, IgE is believed to in resistance such as pollinosis.
