|
Definition
More than 1 labelled secondary antibody can bind to each primary antibody --> protein is amplified |
|
|
Term
Microscopic technique: stain preparations are examined as ordinary light passes thru |
|
Definition
|
|
Term
Microscopic technique: uses differences in refractive index of components to produce an image w/o staining, allowing observation of living cells |
|
Definition
|
|
Term
Microscopic technique: involves scanning specimen at successive focal planes w/ focused light beam (laser), producing a 3D reconstruction from images |
|
Definition
|
|
Term
Microscopic technique: uses UV light, allowing localization of probes which can be much more specific than routine stains |
|
Definition
|
|
Term
Microscopic technique: Scans e- beam across specimen coated w/ thin layer of heavy metal. Reflected and secondary e-s from specimen are produced into 3D ultrastructural image |
|
Definition
Scanning Electron Microscopy (SEM) |
|
|
Term
Microscopic technique: sends electromagnetically focused beam of e-s at very high voltage thru ultra-thin sections of tissues. Involves heavy metal ions that associate at different e- densities w/ components, improving contrast |
