特美汀对革兰阳性菌、阴性菌、好氧及厌氧菌均有抑制作用。其组分为替卡西林钠及克拉维酸钾 (Ticarcillin Sodium and Clavulanate Potassium),替卡西林钠与克拉维酸钾的比例为 15:1,替卡西林钠是青霉素类杀菌 剂,克拉维酸则是一种不可逆性高效 β-内酰胺酶抑制剂。多种革兰氏阳性菌 (G+)和阴性菌 (G-) 都能产生 β-内酰胺酶,这类酶能在青霉素作用于病原体之前将其破坏。克拉维酸钾通过阻断 β-内酰胺酶破坏细菌的防 御屏障,恢复替卡西林钠的杀菌作用。克拉维酸钾单独抗菌作用甚微,但与替卡西林钠配合使用后使其成为具有广谱杀菌作用的抗生素,适用于多种细菌感染性疾病的治疗。在植物转基因试验中常用于抑制农杆菌生长,同时对植物愈伤的副作用较小,特别适合在多种植物的愈伤组织农杆菌侵染试验后期的筛选培养基中使用,能 获得很好的抑菌效果,同时不影响阳性苗的分化。

使用方法:
1、储存液的配制 (200mg/ml):称取 3.2g 特美汀加入 16ml 无菌的去离子水,摇晃混匀溶解,0.22um 滤膜过滤除菌,分装 成单次使用的小包装,-20℃ 可稳定保存两年。
2、常用筛选浓度:特美汀常用于植物转基因试验中农杆菌共培养后的筛选步骤,用于在分化培养基中抑制农杆菌生长,其工 作浓度要根据植物物种、农杆菌侵染液中农杆菌浓度、共培养时间进行调整,一般番茄:300 ug/ml;烟草:200 ug/ml;油菜:350 ug/ml。
3、特美汀溶液不耐高温,在使用时若需加热培养基,需等待培养基温度降低到 55℃ 以下,再加入适量特美汀储存液,混匀 后使用。

Timentin exerts inhibitory effects against Gram-positive bacteria, Gram-negative bacteria, aerobic bacteria and anaerobic bacteria. It is composed of Ticarcillin Sodium and Potassium Clavulanate at a ratio of 15:1. Ticarcillin Sodium is a penicillin bactericidal agent, while clavulanic acid acts as an irreversible and high-efficiency β-lactamase inhibitor.A wide range of Gram-positive (G+) and Gram-negative (G-) bacteria can produce β-lactamase, which degrades penicillin antibiotics before they take effect on pathogenic bacteria. By inhibiting β-lactamase, Potassium Clavulanate blocks this bacterial resistance mechanism and restores the bactericidal activity of Ticarcillin Sodium. Potassium Clavulanate alone has negligible antibacterial activity, but when combined with Ticarcillin Sodium, the mixture becomes a broad-spectrum bactericidal antibiotic applicable to the treatment of various bacterial infectious diseases.In plant transgenic experiments, Timentin is commonly used to suppress the growth of Agrobacterium with minimal side effects on plant callus. It is especially suitable for addition to screening medium in the later stage of Agrobacterium-mediated transformation of callus tissues from various plant species, delivering excellent bacteriostatic performance without interfering with the differentiation of positive transgenic seedlings.

Product Composition and Formula:
|
Usage Method:
1. Preparation of stock solution (200 mg/mL): Weigh out 3.2 g of Timentin powder and dissolve it in 16 mL of sterile deionized water by shaking thoroughly. Sterilize the solution via filtration with a 0.22 μm membrane filter, aliquot into single-use portions, and store at -20 °C for up to 2 years with stable performance.
2. Routine screening working concentration: Timentin is widely applied in the screening stage after Agrobacterium co-cultivation during plant transgenic experiments to inhibit Agrobacterium growth in differentiation medium. The working concentration should be adjusted according to plant species, Agrobacterium concentration in infection suspension and co-cultivation duration. Typical concentrations are listed as follows: 300 μg/mL for tomato, 200 μg/mL for tobacco, and 350 μg/mL for rapeseed.
3. Timentin solution cannot withstand high temperature. If the culture medium needs to be heated prior to use, cool the medium down below 55 °C before adding the required amount of Timentin stock solution and mix evenly for subsequent use.
Remarks:
Solid Timentin is a white powder freely soluble in water. Freshly prepared Timentin solution appears colorless and transparent. After frozen storage at -20 °C and repeated freeze-thaw cycles, the solution will darken to a tan-yellow hue, which does not impair its effectiveness.
Precautions:
1. Neither solid Timentin nor Timentin solution is autoclavable.
2. Solid Timentin and its aqueous solution shall not be stored at room temperature for long-term preservation; low-temperature storage is required.
3. Strictly follow aseptic operation to prevent contamination. This product is hazardous to human bodies. Handle with caution and take proper protective measures to avoid direct skin contact or inhalation.
4. This product is for research use only by professional researchers and shall not be adopted for clinical diagnosis or medical treatment.
5. Wear a lab coat and disposable nitrile gloves during operation for personal safety and health
