   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. ... The detection antibody can be covalently linked to an enzyme, or can itself be detected by a secondary antibody which is linked to an enzyme through bioconjugation.
2. close

   Tetramer assay

   A tetramer assay is used to detect the presence of antigen specific T-cells. ... The tetramer can be detected by flow cytometry via the fluorescent label.
3. close

   Comet assay

   The comet assay is a versatile technique for detecting damage and with adjustments to the protocol can be used to quantify the presence of a wide variety of DNA altering lesions (damage). The damage usually detected are single strand breaks and double strand breaks.
4. close

   SNP genotyping

   If only the first probe’s fluorophore wavelength is detected during the assay then the individual is homozygous to the wild type. ... Ligation does not generally occur in the presence of a mismatched 3' base.
5. close

   Bradford protein assay

   In SDS concentrations above CMC, the detergent associates strongly with the green form of coomassie dye, causing the equilibrium to shift, thereby producing more of the green form, which causes an increase in the absorbance at 595 nm independent of protein presence. ... Assay
6. close

   AFP-L3

   The L3 isoform is specific to malignant tumors and its detected presence can serve to identify patients whom need increased monitoring for the development of HCC in high risk populations (i.e. chronic hepatitis B & C and/or liver cirrhosis). ... AFP-L3% assay
7. close

   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 cleavage pattern of the DNA in the absence of a DNA binding protein, typically referred to as free DNA, is compared to the cleavage pattern of DNA in the presence of a DNA binding protein.
8. close
   

   Electrophoretic mobility shift assay

   When these conditions are not met a second band might be seen in lane 3 reflecting the presence of free DNA or the dissociation of the DNA-protein complex. ... This method is referred to as a supershift assay, and is used to unambiguously identify a protein present in the protein-nucleic acid complex.
9. close

   Lowry protein assay

   The product becomes reduced to molybdenum/tungsten blue and can be detected colorimetrically by absorbance at 650nm. ... Presence of strong acids or ammonium sulfate can interfere with the assay.
10. close

    History of radar

    The system detected presence of ships up to 3 km, and he planned to extend its capability to 10 km. ... Eventually the Germans gave up trying to bomb them.
