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.

monoclonal antibody âan antibody produced by a single B cell or its identical progeny that is specific for a given antigen. Monoclonal antibodies are used as research tools for binding to specific protein molecules and are invaluable in research, medicine, and industry.hen an antibody attaches to an antigen, it helps the body destroy or inactivate the antigen. antigen âa substance or molecule that is recognized by the immune system. The antigen can be from foreign material such as bacteria or viruses.
