Sandwich ELISA

The Survivin antibody is widely used in apoptosis studies, and as a cellular marker. Today, biochemists have a wide range of Survivin antibody products to choose from, suitable for use in Western Blot, Chromatin Immunoprecipitation (ChIP), Immunofluorescence and similar assays.

Enzyme-linked immunosorbent assay (ELISA) is a widely used technique for detecting concentration of proteins, using enzyme tagged antibodies with which react with dyes to produce a colorimetric or fluorescent signal. Sandwich ELISA takes this one step further, by pre-coating plastic wells with a known concentration of a "capture" antibody which reacts specifically to the antigen under test. A secondary antibody is then applied, tagged with an enzyme.

The best antibody suppliers offer far more than just individual peptides and reagents. They also supply a range of antibody kits which contain everything a scientist needs to perform a particular experiment in one convenient package.
