Cell Technology's Nonmammalian-Based Blocker contains a proprietary
non-mammalian formulation based on fish proteins, plus molecular
stabilizers that provide a high degree of blocking efficiency.
EBB200 was designed for antigen-down ELISA formats, and for sandwich
assays with high background problems. This formulation is a
heterogeneous mixture of small molecules capable of blocking both
the nonspecific binding sites of the absorbed protein, as well as
the unoccupied regions of the polystyrene plate that are not
sterically accessible to larger traditional mammalian blocking
reagents, thereby reducing background noise. The small size of these
unique blockers results in minimal steric hindrance to key epitope
regions of target coated proteins, thus enhancing specific signal
generation.
EBB200 reduces the possibility of false-positives generated from
endogenous antibodies in the sample reacting with plate blocking
proteins. It is particularly useful when working with human, swine,
and bovine serum samples, as there is little interaction with the
blocking molecules resulting in lower backgrounds.
