What are the serotypes of antibodies Why are there so many serotypes? Food immunology for answers.

The serum works on the antibodies inside, so it should be the type of antibody in the serum, not the serotype of the antibody. Immunologically immunogenic macromolecules (in fact, almost all macromolecules are more or less immunogenic) can induce the production of antibodies to form the corresponding serum, so the serotypes are endless.

In food immunology, antibodies are made to the surface characteristic proteins of bacteria that may contaminate food, and the corresponding serum is formed to determine the type of pathogenic microorganisms in food.

Serotype of immunoglobulin.

Immune proteins are macromolecular proteins, which have various properties of antigens, and are good antigens for xenografts, allogeneics, and even the host itself, and are antigenic complexes with a variety of antigenic determinants. This heterogeneity of Ig molecules reflects the hereditary differences in antibody-forming cells and represents the genetic variability of antibody molecules at different levels; It is usually detected by serological methods, which divide Ig and its peptide chains (H and L) into different serotypes.

Hello, is there any other tumor or elevated inflammatory marker?

Antibodies to antigens in red blood cells vary from person to person.

The more important blood group systems in medicine are ABO, RH, MNSS, etc.

ABO blood group is classified based on the presence or absence of A and B antigens on the red blood cell membrane. Those with only A antigen on the red blood cell membrane are type A; Those containing only B antigen are type B; Those who contain both A and B antigens are AB blood group; Those who do not have either antigens A or B are type O.

People with different blood types have different antibodies in their serum, but they do not contain antibodies that correspond to their own red blood cell antigens. In the serum of people with blood type A, only anti-B antibodies are contained; People with blood type B have only antibodies to antibodies in their serum; There are no anti-A and anti-B antibodies in the serum of blood type AB; On the other hand, the serum of type O blood contains anti-A and anti-B antibodies.

The specificity of the various antigens of the ABO blood group system is determined by the glycoproteins or glycolipids contained on the erythrocyte membrane.

In the Rh blood group, those who have a D antigen on red blood cells are usually called Rh-positive, and those who lack a D antigen on red blood cells are called Rh-negative.

The Rh blood group is characterized by the absence of natural antibodies against Rh in the human serum, and only when Rh-negative people receive Rh-positive blood, they will produce anti-Rh immune antibodies through humoral immunity.

Immunoglobulin E is within the normal range, don't worry, I wish the baby a healthy and happy life
