A protein has a sedimentation coefficient of 2.6S, when ultracentrifuged in a 0.1 M NaCl solution; the same protein has a sedimentation coefficient of 4.6S, when centrifuged in a 1.0 M NaCl solution. This change in the sedimentation rate at 1.0 M NaCI, most likely occurs because the protein (one word = verb).

Protein a will fold into its native state only when protein b is also present in the solution however  protein b can fold itself into native confirmation without the presence of protein a which of the following is true

Calculate the amount of protein (in mg) in Sample 1 if the measurement at A280 = 0.636, taking into account the dilution factor as per question 6 (100ul) and the total volume of extract as per question 4 (140ml). Give your answer as a number with no decimal places.

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).

Suppose you have a concentration of 356ng/uL for Sample A.  How many ng of protein will that be?

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