The Continental Shelf. The Continental Shelf is the gently sloping undersea plain between a continent and the deep ocean. The continental shelf is an extension of the continent's landmass under the ocean. Much of the continental shelf was exposed dry land during glacial periods.During interglacial periods, like today, the shelf is submerged under relatively shallow waters.he continental shelf is an extension of the continent's landmass under the ocean.

Indirect ELISA, conventional but efficient. Indirect ELISA is a two-step ELISA which involves two binding process of primary antibody and labeled secondary antibody. The primary antibody is incubated with the antigen followed by the incubation with the secondary antibody.However, this may lead to nonspecific signals because of cross-reaction that the secondary antibody may bring about. 1. Micro-well plates are incubated with antigens, washed up and blocked with BSA. 2.he primary antibody is incubated with the antigen followed by the incubation with the secondary antibody.

Antibody Structure. Antibodies are little glycoprotein molecules that are the major components of the humoral immune system. They aren't just little globs of nothing, however. They are highly specialized structures created to go after very specific invaders in your body.his means that when a white blood cell, called a plasma cell, produces an antibody for a specific pathogen, it will alter the variable region such that the antibody will be able to attach to a very specific pathogen, but not another.
