What is bound to the surface of a B cell?
Antibodies are bound to the surface of a B cell. These antibodies serve as receptors that allow the B cell to recognize and bind to specific antigens. This binding process helps initiate the immune response by activating the B cell to differentiate into plasma cells that secrete antibodies.
How cold is liquid helium?
Solid Helium is difficult to produce; at normal atmospheric pressure it will not solidify, even at 00 Kelvin. ( aka Absolute zero, or -2730C )Exactly how cold Helium must be to solidify depends on the pressure it is under. The standard way to show the numbers is on a phase diagram. These can be found on Google. Since we can't put diagrams on Wiki Answers, you will only get one of the possible answers here.If you cool Helium to 20 K, it will solidify at about 2.5 MPa. This is about 25 atmospheres or a little under 400 p.s.i. 2.5 MPa is close to the lowest pressure at which Helium will solidify.Note. Helium has more than one isotype; the numbers above are for the common isotope Helium 4.
Are proteins antibodies?
Yes antibodies are protien.Antibodies (also known as immunoglobulins,abbreviated Ig) are gamma globulin proteins that are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses. They are typically made of basic structural units-each with two large heavy chains and two small light chains-to form, for example, monomers with one unit, dimers with two units or pentamers with five units. Antibodies are produced by a kind of white blood cell called a plasma cell. There are several different types of antibody heavy chains, and several different kinds of antibodies, which are grouped into different isotypes based on which heavy chain they possess. Five different antibody isotypes are known in mammals, which perform different roles, and help direct the appropriate immune response for each different type of foreign object they encounter.Though the general structure of all antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with slightly different tip structures, or antigen binding sites, to exist. This region is known as the hypervariable region. Each of these variants can bind to a different target, known as an antigen. This huge diversity of antibodies allows the immune system to recognize an equally wide diversity of antigens. The unique part of the antigen recognized by an antibody is called an epitope. These epitopes bind with their antibody in a highly specific interaction, called induced fit, that allows antibodies to identify and bind only their unique antigen in the midst of the millions of different molecules that make up an organism. Recognition of an antigen by an antibody tags it for attack by other parts of the immune system. Antibodies can also neutralize targets directly by, for example, binding to a part of a pathogen that it needs to cause an infection.The large and diverse population of antibodies is generated by random combinations of a set of gene segments that encode different antigen binding sites (or paratopes), followed by random mutations in this area of the antibody gene, which create further diversity. Antibody genes also re-organize in a process called class switching that changes the base of the heavy chain to another, creating a different isotype of the antibody that retains the antigen specific variable region. This allows a single antibody to be used by several different parts of the immune system. Production of antibodies is the main function of the humoral immune system.
