   Enzyme assay

   These types of assay can be extremely sensitive, since the light produced can be captured by photographic film over days or weeks, but can be hard to quantify, because not all the light released by a reaction will be detected. ... Radioactivity is usually measured in these procedures using a scintillation counter.
2. close

   Comet assay

   The individual strands of DNA lose their compact structure and relax, expanding out of the cavity into the agarose. ... The comet assay is an extremely sensitive DNA damage assay.
3. close

   Measuring instrument

   Time-points in the past can be measured with respect to the present of an observer. ... Blood-related parameters are listed in a blood test.
4. close

   Semen quality

   A man's sperm are mixed with hamster eggs that have had the zona pellucida (outer membranes) removed, and the number of sperm penetrations per egg is measured. ... Sperm chromatin assay
5. close

   Enzyme kinetics

   Spectrophotometric assays are most convenient since they allow the rate of the reaction to be measured continuously. ... On the left is shown a typical progress curve for an enzyme assay.
6. close

   Telomere

   Telomere Length Assay ... Researchers measured serum vitamin D concentrations in 2160 women aged 18-79 years (mean age: 49.4) from a large population-based cohort of twins.
7. close

   MELISA

   The level of reactivity is measured as a Stimulation Index (SI), against the naïve lymphocytes from the unexposed sample (negative control). ... The T-cell proliferative assay in the diagnosis of Lyme disease.
8. close

   Military parade

   At Ease: a modified position of attention in which the left foot is moved to shoulder width (typically measured as exactly 12 inches) and the hands are placed behind the back with arms fully extended. ... Member may relax their muscles and make minimal movements.
9. close

   Enzyme inhibitor

   Enzyme assay ... BindingDB, a public database of measured protein-ligand binding affinities.
10. close

    Magnesium in biology

    All ions passing across the membrane contribute to the measured current. ... "Development and use of chlorotetracycline fluorescence as a measurement assay of chloroplast envelope-bound Mg2+".
