Given 10 gram of vitamin C (E=0.18), we can make ml of isotonic Vitamin C solution.

Which of the following is NOT a unit of concentration?     All of these options are units of concentration.     mM     Moles/Liter     Molar   You gathered your data from Lab , and found the following values: Total Activity of lysozyme in HEW: 14 units Total Activity of lysozyme in carb 1: 21 units Total amount of protein in HEW: 70 mg Total amount of protein in Carb 1: 15 mg Calculate the extent of purification of lysozyme in Carb 1. A   7 fold B   150% C   15 fold D   70%

A purified protein fraction has a total sample volume of 360 µL.  The sample has a corrected A280 of 0.484, and the blank corrected A280 was 0.052.  (Both values were measured with a path length of 1.00 cm.)  If 5.00 µL of the sample was used in a reaction, calculate the mass of protein in the reaction (in µg).

List at least three test reactions for lipids. Describe its principle and its positive result

To prepare a gel sample, you want to load 50 ng total of protein/well. You have added 200 μL of protein in 800 µL reagent and measured your sample by Bradford A595 to be 0.7 mg/mL - your dilution is unaccounted for at this point. Assuming a total final volume of 20 μL, what volume of protein sample, buffer and 4X SDS PAGE Loading Dye needs to be mixed to create a final sample of 50 ng protein in 20 μL?

In quantitative determination of protein using spectrophotometer how can I plot the absorbance vs wavelength for the proteins given the transmittance values?

A spheroidal bacterium with a diameter of 1.0 μm (micrometer, 1 μm = 10-6) contains 25,000 molecules of the protein hexokinase. What is the molar concentration of the protein inside the cell?
