Methicillin is a narrow-spectrum β-lactam antibiotic, acts by inhibiting penicillin-binding proteins (PBPs). Methicillin is active against Staphylococcus aureus and Staphylococcus epidermidis that are resistant to other penicillins.Methicillin can be used for the research of skin infections, osteomyelitis, and endocarditis.

For research use only. We do not sell to patients.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
