Cefotaxime Solution（100mg/ml）

● 产品包装：

Formula: C₁₆H₁₆N₅O₇S₂Na

MW: 477.45

Appearance: Pale Light Yellow Solution

● 产品简介：

Cefotaxime is an inhibitor of cell wall synthesis and chemically related to penicillin.  It is highly effective against Gram-negative bacteria.  Cefotaxime is often used in transformation research for the elimination of Agrobacterium tumefaciens.  Additionally, cefotaxime also has stimulatory effect.  It is founded that addition of cefotaxime to medium enhances shoot organogenesis in vitro for many plants (apple, barley, grain, maize, etc.).

A concentration of 90 μg/mL is recommended to achieve microbe toxicity. Cefotaxime concentrations should not exceed 100 μg/mL in order to avoid toxicity for plants (though plant toxicity may be higher or lower than 100 μg/mL for different plant species).
