Antibody Resources

Section Overview:

Antibodies are a large family of glycoproteins produced by specialized cells of the vertebrate immune system in response to foreign molecules (antigens). The interaction of an antibody with an antigen is the foundation upon which all immunochemical techniques have been developed. In confocal microscopy, such techniques are often extremely useful, enabling the researcher to localize antigens in cell cultures and tissue sections by utilizing antibodies labeled with fluorescent dyes that can be readily visualized with a confocal microscope. Also, in order to obtain a stronger signal, oftentimes an unlabeled primary antibody is used in conjunction with a labeled secondary antibody that binds to it. The resources provided in this section include many leading and emerging producers and distributors of primary and secondary antibodies.
