Anesthetic (MS222) Solution Preparation
Anesthetic Solution (Buffered MS222) is commonly used to temporarily immobilize fish and amphibians.
Carbenicillin Solution Preparation
Carbenicillin is an ampicillin analog with structure related to benzyl penicillin. It is effective against Gram-negative bacteria and exhibits limited activity against Gram-positive bacteria. Carbenicillin binds and inhibits the enzymes involved in the synthesis of bacterial cell wall. Since carbenicillin is less sensitive to β-lactamases than ampicillin, it is effective against ampicillin-resistant bacteria. It has … Read more
