The mixing of liquids is critical in microfluidic analytical systems and is often taking place inY-shaped junctions as seen in Figure Q4b. The inlets are 50 μm wide and 50 µm high, andthe outlet is 50 μm wide and 50 μm high. The aim of the device is to analyse IgG with adiffusion coefficient of 4-10 cm²-s¹. Determine the shortest length of the channel to ensurecomplete mixing when the flowrate in each of the inlet channels is 1 µl/h.

The isoelectric point of eIF4a is 5.02. Students are given a sample of cell lysate containing eIF4A at pH 7.4. They are also provided with two buffers of pH 7.4 to use for ion exchange chromatography. One buffer has a very high salt concentration (1 M), the other has a low salt concentration (0.1 M). Mariela decides to use an anion exchange column, while Ashok chooses a cation exchange column. Who made the better decision? Provide a detailed explanation of why one student will end up with a purer sample of eIF4A. Which buffer will you use while washing away impurities (high or low salt), and which would you use to remove eIF4A from the column? Explain your choice.

In this problem, you will design a filter system for a flow cytometer. The four fluorescent dyes are FITC,PE, PE-TR,and PE-Cy5. Their emisison spectra are provided below. Detectors are arranged as shown in thefigure below. The FITC signal is detected from Filter 1, the PE signal from Filter 2, the PE-TR signal fromFilter 3 and the PE-Cy 5 signal from Filter 4. Part 4.1Provide a rationale for the order in which the filters are arranged with respect to the unfiltered signal. Part 4.2You are given 9 candidates from which you have to choose 4 for the filters in the diagram above.

Protein concentration can readily be determined using the Beer-Lambert law: A = e l c where A = absorbance e = molar absorption coefficient (M-1cm-1) l = light path length (cm) c = concentration (M) If the molar absorption coefficient at 280 nm for yeast ADH is 48860 M-1cm-1 and a 10 mL solution of the protein has an absorbance at 280 nm of 0.4 (as measured by a spectrometer with pathlength 1 cm), then what is the concentration of the protein solution (in μM)? i.e. concentration = ______ μM If the molecular weight of the protein is 36849, what is its concentration in mg/mL? i.e. concentration = _______ mg/mL For each part of the question, show your calculations to arrive at your answers.
Phosphate buffered saline (PBS) is a physiological buffer often used in biology experiments. Because the concentrations are very low and small amounts are difficult to weigh out, it is often prepared as a 10X stock solution meaning that it is prepared at 10 times the working concentration which is 1X. 1X PBS is made up of Na2HPO4 10 mM (MW 141.9 g.mol-1); KH2PO4 8 mM (MW 136.08 g.mol-1), NaCl 137 mM (MW 58.44 g.mol-1) and KCl 74.5 mM (MW 74.5 g.mol-1). You decide to prepare a 1 L 10X solution of PBS. What is the Molar (M) concentration of each of the components in you 10X stock. Write your answers in the table below. How much of each of the components should you weigh out to prepare 1L of the 10X stock solutions. Write your answers in the table below.
