   Assay

   Trofile assay: Used to determine HIV tropism. ... The number of cells which secrete those particular substances can be determined using a related technique, the ELISPOT assay.
2. close

   Enzyme assay

   Fluorometric assays use a difference in the fluorescence of substrate from product to measure the enzyme reaction. ... These assays can be used to measure reactions that are impossible to assay in any other way.

   Electrophoretic mobility shift assay

   This method is referred to as a supershift assay, and is used to unambiguously identify a protein present in the protein-nucleic acid complex.
4. close

   SNP genotyping

   Because SNP alleles only differ in one nucleotide and because it is difficult to achieve optimal hybridization conditions for all probes on the array, the target DNA has the potential to hybridize to mismatched probes. ... Several developments have extended the original Invader assay.

   DNase footprinting assay

   A DNase footprinting assay is a DNA footprinting technique from molecular biology/biochemistry that detects DNA-protein interaction using the fact that a protein bound to DNA will often protect that DNA from enzymatic cleavage. ... The gel is then used to expose a special photographic film.
6. close

   Clonogenic assay

   If the slopes of their survival curves differ significantly, then a potentiating effect may be evident and could be studied further. ... "Clonogenic assay of cells in vitro".

   Hallmark

   Systems Differ from Nation to Nation ... For this reason, and that off-cuts from sprues are often used for assay, many articles are sent unfinished to the assay office for assay and hallmarking.

   ELISA

   Enzyme-Linked ImmunoSorbent Assay, also called ELISA, Enzyme ImmunoAssay or EIA, is a biochemical technique used mainly in immunology to detect the presence of an antibody or an antigen in a sample.

   Chemotaxis assay

   For detection of cells general staining techniques (e.g. trypan blue) or special probes (e.g. mt-dehydrogenase detection with MTT assay) are used.

    Two-hybrid screening

    The considerations and methods used in the construction and delivery of these sequences differ according to the needs of the assay and the organism chosen as the experimental background.
