To find the volume needed, we need to use the equation:
volume (in ul) = amount of protein (in micrograms) / concentration of protein (in mg/ml).
Given that the concentration of protein is 1.9 mg/ml and the amount of protein needed is 30 micrograms:
volume (in ul) = 30 micrograms / 1.9 mg/ml.
To convert the units, we need to convert micrograms to milligrams:
1 microgram = 0.001 milligrams.
Therefore, 30 micrograms = 0.03 milligrams.
Substituting these values into the equation:
volume (in ul) = 0.03 mg / 1.9 mg/ml.
Simplifying the equation:
volume (in ul) = 0.03 / 1.9 ml.
Converting milliliters to microliters (1 ml = 1000 ul):
volume (in ul) = (0.03 / 1.9) * 1000 ul.
Calculating the result:
volume (in ul) = 15.789473684210527 ul.
Therefore, you would need approximately 15.79 microliters of the sample to have exactly 30 micrograms of protein.
If the sample has 1.9 mg/ml protein, how many microliters (ul) would you need in order to have exactly 30 micrograms of protein?
