the Marquis test was used on a sample suspected to contain amphetamine in a “field” sample, so the sample is likely impure. The resulting color was noted as orange by the test operator . (A) Identify a suitable negative control for this test. (B) Identify a suitable positive control. (C) What properties of the sample can introduce uncertainty in the color determination? (D) How can inter-operator error be reduced in reporting the results of a test like this?

(iii) A patient sample measured using this biosensor in the diagnostic laboratory generates a signal of 142800. The coefficient of variation of the device is 5%. Explain whether the diagnostic lab would have the confidence to report that the sample has a concentration in analyte of 8 nM or…
Provide the Experimental procedure of the following: Example: Ninhydrin Test -The samples needed in this test were 1% casein solution, albumin and gelatin and the reagent used was ninhydrin (Triketohydrindenehydrate or Triketohydrin hydrate). Test tube, test tube stand, pippete, water bath, and spectrophotometer were the materials and equipment used. Ninhydrin reagent in 1-2 drops was added to 0.5 ml of the sample with care. It was mixed and heated to boiling for 1-2 minutes. Then, it was allowed to cool to record the observation. Test that needs Experimental procedure: 1. Heat denaturation Samples: Albumin, gelatin 2. Isoelectric Precipitation Samples: Casein 3. Concentrated Mineral Acids Samples: Albumin 4. Organic Solvents Samples: Albumin

You perform a Bradford assay to determine the concentration of isolated α-lactalbumin. You use 50 μL of a two-fold diluted solution of α-lactalbumin in the assay. You generate a standard curve with the following equation for the line: y = 0.163x + 0.082. The absorbance of your sample was 0.674 AU. What is the concentration of α-lactalbumin, in mg/mL, in your sample? Give your answer to three significant figures.
Imagine you are conducting an Ames test experiment. Based off your results (shown in pictures), answer these questions: 1. Generate a fully labeled graph/figure depicting the data generated in lab (minimally you should include the data from control, 2-NF, and two different test compounds.) 2. Make a bulleted list of 3 distinct and specific observations/patterns seen in your graph/figure - for each observation, indicate specifically where you should look to find the observation on your figure. 3. Write a 5 sentence minimum explanation of the results (i.e., a discussion of the hypothesis, the experimental prediction and the conclusions based on your observations from experimental data)
A nurse reconstituted a vial of 750 mg Cefuroxime Sodium Powder for Injection with 6mL of sterile water for injection. The reconstituted solution was dark amber-colored solution. The package insert states that solution colors range from clear to yellow depending on concentration, diluent, and storage conditions. The nurse was then hesitant to give the patient the solution due to its unusual dark color. Five portions were taken from a batch of cefuroxime sodium. Prior to testing in the instrument, each part was subjected to one of the following conditions: Conditions Specifications Temperature Portion 1: 8°C ± 2°C Portion 2: 30°C ± 2°C Portion 3: 40°C ± 2°C Light Portion 4: Kept in the dark Portion 5: Exposed to direct sunlight 1. Which form of the product – the powder for injection, the reconstituted product, or both – will you subject to the following conditions? Why do you think these forms can best address the problem?
