Divide 1 by the result from Section 2, Step 3 to calculate the actual value of Vmax. Determine the concentration of the enzyme in the original assay (see the raw data). Note: the enzyme concentration is the same for all of the test tubes; only the substrate concentrations vary in the a...
Scientists and technicians often need to calculate the concentration of cells in a suspension. For example, when a patient gets his blood drawn at a doctor’s office, the laboratory can use certain methods to look for the amount of white blood cells in a given volume of blood. This gives ...
How do we calculate the distances to stars? What units do we use, and what are the limitations (if any) of the method used for such calculations? Explain how to determine global average temperatures during the past million years or so. Describe how the effectiveness of a chemical agent can...

Calculation of free vitamin D metabolites Because of the difficulty in measuring the free hormone, some investigators have used the association constants of DBP and albumin for the vitamin D metabolites along with measurements of total metabolite, DBP, and albumin levels to ...

To calculate EC50 in the ISO dose-response assay, data were scaled to 100 for the entire dataset, and values obtained with and without GRK2 were fit to a sigmoidal curve (four-parameter logistic equation) with a variable slope. For the assay of the RH domain mutants, the transfected GRK2...

The function ‘cor’ can calculate the correlation on the scale of 0 to 1, in a pairwise fashion between all samples, then visualise on a heatmap. There are many ways to create heatmaps in R, here I use ‘pheatmap’, the only argument it requires is a matrix of numeric values. ...
