Ahomodimeric protein was found to migrate through sds polyacrilamide gel electrophoresis (sds-page) with a mobility that matched that of a 45-kda standard. what change in the experiment would increase the chances of observing the mobility expected for the 22.5-kda monomer? a. increasing the gel running timeb. adding a reducing agentc. using a higher voltaged. removing the sds

Adding a reducing agent

Explanation:

Homodimeric proteins are formed by non-covalent interactions between two identical proteins (monomers).

Some of these intermolecular interactions are mediated by disulphide bonds which can be broken by a  reducing agent like beta-mercaptoethanol (2-ME).

By adding the reducing agent to the gel, it is probable that the dimer is broken and the band observed will correspond to the two identical 22.5-kDa monomers.

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.
