Experiment 2: Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins

Natural disasters are often not natural disasters‚ but are in fact human disasters. Discuss this statement in relation to seismic events. The word ‘natural’ indicates that humans have not caused the disaster. However‚ human activity can certainly interfere with nature‚ which in turn may either cause a natural disaster or make its effects much worse. Earthquakes can affect people in many different ways in countries all over the world. They are a product of intense seismic activity where plates are

Natural resource Natural resources (economically referred to as land or raw materials) are naturally forming substances that are considered valuable in their relatively unmodified (natural) form. A natural resource’s value rests in the amount and extractability of the material available and the demand for it. The latter is determined by its usefulness to production. A commodity is generally considered a natural resource when the primary activities associated with it are extraction and purification

Titration is a method used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately

Determining Sample Size In the business world‚ sample sizes are determined prior to data collection to ensure that the confidence interval is narrow enough to be useful in making decisions. Determining the proper sample size is a complicated procedure‚ subject to the constraints of budget‚ time‚ and the amount of acceptable sampling error. If you want to estimate the mean dollar amount of the sales invoices‚ you must determine in advance how large a sampling error to allow in estimating the population
