Cefamandole nafate is a pro-drug that is hydrolyzed by plasma esterases to produce cefamandole, second-generation cephalosporin antibiotic with bactericidal activity. Cefamandole nafate is used to study the effects of expression and inhibition of PBP 2A and other penicillin-binding proteins (PDPs) on bacterial cell wall mucopeptide synthesis. Cefamandole binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
