- Why does polyacrylamide gel have small pores?
- Polyacrylamide gel with small pores helps to examine smaller molecules better since the small molecules can enter the pores and travel through the gel while large molecules get trapped at the pore openings. As with all forms of gel electrophoresis, molecules may be run in their native state, preserving the molecules' higher-order structure.
- How are polyacrylamide gels characterized?
- Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best separation and resolution for the proteins of interest.
- What is the difference between agarose gel and polyacrylamide gel?
- Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1−1000 base pairs, based on the concentration used (Figure 1). These gels can be run with or without a denaturant. Gels that are run without a denaturant are referred to as native gels.
- How do you determine the pore diameter of polyacrylamide gels?
- The average pore diameter of polyacrylamide gels is determined by the total concentration of acrylamides (% T with T = Total concentration of acrylamide and bisacrylamide) and the concentration of the cross-linker bisacrylamide (%C with C = bisacrylamide concentration).
