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.

An antibody produced by a clone or genetically homogeneous population of hybrid cells (i.e., hybridoma); hybrid cells are cloned to establish cell lines producing a specific antibody that is chemically and immunologically homogeneous; a mainstay of immunologic research and medical diagnosis.ny of a class of highly specific antibodies produced by the clones of a single hybrid cell formed in the laboratory by the fusion of a B cell with a tumor cell and widely used in medical and biological research.
