1. What are the 4 types of chromatography?
- Affinity Chromatography
- Ion Exchange Chromatography
- Size Exclusion Chromatography (Gel Filtration)
- Thin-Layer/Column Chromatography
2. Affinity Chromatography
- Separates based on specific binding interactions
3. Ion Exchange Chromatography
- Separates based on charge; cation exchange binds positive molecules, while
anion exchange binds negative ones
4. Size Exclusion Chromatography (Gel Filtration)
- Separates based on size; larger molecules elute first because they don't enter
small pores in the stationary phase
5. Thin-Layer/Column Chromatography
- Separates based on polarity; nonpolar compounds travel farther in a nonpolar
solvent, while polar compounds stick to the stationary phase
6. Serial Dilution Formula
- Cf = Ci (1/dilution factor)^n
, - Cf = final concentration
- Ci = initial concentration
- n = number of dilution steps
7. Step = n
- Fold = dilution factor
8. King Henry Died By Drinking Chocolate Milk
- Kilo (k) → Hecto (h) → Deca (da) → Base → Deci (d) → Centi (c) → Milli
(m)
- Each movement over is a factor of 10
9. Dilution Formula
- C1×V1 = C2×V2
- C1 = Initial (stock) concentration
- V1 = Volume of stock needed
- C2 = Final (desired) concentration
- V2 = Final volume
10. Math Percentage Questions
- Mass = Percentage × Volume
11. Math Mass Questions Given Concentration and Volume
- Mass = Concentration × Volume
12. Beer-Lambert's Law
, - A=εcl
- A - absorbance
- ε - molar absorptivity
- c - concentration
- l - path length
13. BSA Standard Curve
- X-axis: BSA Concentration (µg/mL or mg/mL)
- Y-axis: Absorbance
- Scatter plot of absorbance vs. concentration and fit a linear regression line
- Used to determine the protein concentration of unknown samples by plugging
in their absorbance values
14. Molarity
- M = moles of solute/liters of solution
15. What legislation prohibits bias that is based on information derived from DNA
testing?
- Genetic Information Nondiscrimination Act
16. General good workplace safety behavior
- Following safety protocols and reporting unsafe conditions to a supervisor
17. Safety Shower Location
- Toxic or Poisonous Materials
- Biohazard
