An assay is a procedure in molecular biology for testing and/or measuring the activity of a drug or biochemical in an organism or organic sample. A quantitative assay may also measure the amount of a substance in a sample. Bioassays and immunoassays are among the many varieties of specialized biochemical assays. Other assays measure processes such as enzyme activity, antigen capture, stem cell activity, and competitive protein binding. Assay varietiesThis section does not cite any references or sources.

Q. Besides keeping volume of solutions, timing, temperature constant. Thank you. Asked by sky_blue - Mon Sep 3 08:20:07 2007 - - 1 Answers - 0 Comments A. Besides volume of solutions, timing, and constant temperature, one important step that should be taken is to have a good standard curve. A good standard curve should show a mathematic relationship between the concentrations of enzyme used and the colorimetric readout. A good standard curve can be used as a good internal control for many differing variables. As absorption of light will be measured, the spectrophotometer should be calibrated, or rather, steps should be taken to make sure it is working as expected. A good standard curve can tell you if it is working properly. The experiment should contain 'zeros' in which no enzyme is added at all. You mentioned time as a variable which was already considered. This can be an especially… [cont.] Answered by cl3v3r boy - Mon Sep 3 09:55:19 2007 How does methylation interference assay works? Q. I'm reading a paper where they used this assay to determine which nucleotides participate in binding of a transcription factor. I, however, have not previously learned about this assay and don't seem to find a good description and explanation of its principles online. Can you explain in or direct me to a site where it is explained? Asked by Kaytee - Mon Feb 26 14:46:21 2007 - - 1 Answers - 0 Comments A. Answered by ger - Mon Mar 5 16:01:58 2007 Why do we need to dilute proteins for the Bradford Assay?
Q. What is the reason we dilute the proteins and not just use the original cell fractions? Do we need a solution that has more or less protein in it to get a good absorbance? Asked by ruz - Mon Jul 6 15:25:29 2009 - - 3 Answers - 0 Comments A. Beer's Law breaks down at high concentrations. Dilute samples give a reaction on the linear portion of the curve. One of the disadvantages of the assay is that it has only a fifty- to one-hundred-fold working range. Answered by novangelis - Mon Jul 6 15:35:37 2009 From Yahoo Answer Search: "Assay" |
