Objectives To be able the students to differentiate and observe what the branded antiseptics and disinfectants can do. Methodology Materials and Procedures In order to start the activity‚ we cooked agar where we cultivated the bacteria (Staphylococcus epidermis). After plating and cooling the agar inside the petri dish‚ we foreplate the bacteria by using a cotton swab. We prepared two (2) petri dishes. One is for the bacteria and the other one is by swabbing the cotton swab to any surface and then

with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin). The extracted plasmid DNA is important as it contains ampicillin-resistant gene. As such‚ E. coli cells that have taken up this plasmid DNA will be resistant to ampicillin and survive‚ hence growth of colonies will be observed on the agar plates. One of the rationales behind heat shock method is to create pores‚ allowing uptake of plasmid DNA (Panja et
