Protein and a functioning immune system.
No
Vaccines stimulate production of antibodies.
Antibodies
Plasma donors are greatly needed to provide researchers with the antibodies needed to make positive controls in diagnostic tests for patients seeking diagnosis.
No they do not. B cells synthesize the antibodies.
Antibodies are made in the lymph nodes.
Treating dissociated cells with certain antibodies can disrupt cell-cell adhesion molecules or signaling pathways that are necessary for cells to reaggregate properly. This can prevent the cells from recognizing each other and forming the correct interactions needed for reaggregation.
Function of antibodies is to neutralizes the antigens that enters.
antibodies fight infections
The blood cells detect the pathogen The pathogens release toxins The blood cells make antibodies to fit the toxins ( they have to be a specific shape) The antibodies stick the bacteria together ready to be engulfed by he white blood cells The White blood cells remember the antibodies needed for that pathogen so they can make antibodies quicker next time the pathogen invades
Antibodies will eventually form but it takes 7-10 days for that to happen.
antibodies are produced by plasma cells of B-cells.
