After seroconversion, sufficient concentration of the specific antibody exists in the blood, and the serological assay will detect the antibody. The individual is now seropositive for the antibody. [14] During seroconversion, when the amounts of antibody and antigen are very similar, it may not be possible to detect free antigen or free ...
Vitellogenin provides the major egg yolk protein that is a source of nutrients during early development of egg-laying vertebrates and invertebrates.Although vitellogenin also carries some lipid for deposition in the yolk, the primary mechanism for deposition of yolk lipid is instead via VLDLs, at least in birds and reptiles.

Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...
It defines seroconversion and starts the conversation about the response to antigen and antibody formation. It also touches on the importance of the tests used to detect antibodies. Overall, the only critique I have is that it is written at a high-grade level with complex sentences and vocabulary.
A viral titer is the lowest concentration of a virus that still infects cells. To determine the titer, several dilutions are prepared, such as 10 −1, 10 −2, 10 −3, ... 10 −8. [1] The titer of a fat is the temperature, in degrees Celsius, at which it solidifies. [4] The higher the titer, the harder the fat.
Animals frequently used for polyclonal antibody production include chickens, goats, guinea pigs, hamsters, horses, mice, rats, and sheep. However, the rabbit is the most commonly used laboratory animal for this purpose. Animal selection should be based upon: the amount of antibody needed,
The following outline is provided as an overview of and topical guide to zoology: . Zoology – study of animals.Zoology, or "animal biology", is the branch of biology that relates to the animal kingdom, including the identification, structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
ANAs are found in many disorders, as well as some healthy individuals. These disorders include: systemic lupus erythematosus (SLE), rheumatoid arthritis, Sjögren syndrome, scleroderma, polymyositis, dermatomyositis, primary biliary cirrhosis, drug induced lupus, autoimmune hepatitis, multiple sclerosis, discoid lupus, thyroid disease, antiphospholipid syndrome, juvenile idiopathic arthritis ...
