Goal

To extract protein samples from the bacterial host, run them through an SDS-PAGE gel, and use antibodies to detect specific proteins in the size-separated protein samples. This technique is useful for confirming the presence of a particular protein inside or outside of the bacterial host.

Protocol

Day 1

Induction and Overnight Incubation of Bacterial Culture

Obtaining Supernatant and Lysate Samples from Bacterial Culture

Running an SDS-PAGE on Supernatant/Lysate Samples

Transferring the SDS-PAGE Gel to the Membrane

Day 3

Primary Antibody Staining (Overnight)

Day 4

Secondary Antibody Staining
