1 Application of Timentin
Plant tissue culture is widely used in plant research, such as genetic engineering, model plants, and crop breeding. Contamination of seedlings during tissue culture is a very troublesome issue, among which Agrobacterium is a common Gram-negative bacterium found in soil. It can infect the injured parts of most dicotyledonous and gymnosperm plants under natural conditions. Cells at the injured sites secrete a large amount of phenolic compounds, which attract Agrobacterium to these cells and induce the formation of crown galls or hairy roots.
Timentin is a new type of antibiotic that effectively inhibits Agrobacterium.
2 Principle of Action of Timentin
Timentin has a broad spectrum of antibacterial activity against Gram-positive and negative bacteria, as well as aerobic and anaerobic bacteria. Its components are Ticarcillin Sodium and Clavulanate Potassium, with a ratio of 15:1 based on the effective acid content. Ticarcillin is a penicillin-like bactericidal agent, while Clavulanate is an irreversible and highly effective β-lactamase inhibitor.
Many Gram-positive (G+) and negative (G-) bacteria can produce β-lactamase, an enzyme that can destroy penicillin before it acts on the pathogen. Clavulanate blocks the action of β-lactamase, breaking down the bacterial defense barrier and restoring the sensitivity of Ticarcillin. Clavulanate Potassium has minimal antibacterial activity on its own, but when combined with Ticarcillin, it makes the product a broad-spectrum bactericidal antibiotic suitable for empirical treatment of a wide range of bacterial infections.
3 Advantages of Timentin
- Minimal impact on plant materials: Particularly minimal impact on the formation of callus tissue and plant regeneration.
- Suitable for the transformation process of difficult-to-transform materials: Timentin can be used when plants are difficult to inhibit with other antibiotics.
- Higher efficiency in inhibiting Agrobacterium: Timentin is more efficient in inhibiting common plant Agrobacterium than carbenicillin and cephalothin.
4 Preparation Method (for reference only)
- Usage concentration: In plant tissue culture, the recommended usage concentration is 200-400 mg/mL.
- Culture medium preparation: Newly prepared solid culture medium should be sterilized at high temperature and pressure at 121°C for 15-20 minutes. After sterilization, remove the culture medium (if it is pre-prepared solid culture medium, it can be heated and dissolved in a microwave oven first). When the culture medium cools to about 50°C, add 0.1% Timentin stock solution (v/v) in a laminar flow cabinet, mix well, and then pour the culture medium into sterile culture vessels for later use.
