LBA4404菌株为Ach5型背景,核基因中含有筛选标签---利福平抗性基因Rif。为了便于转化操作,此菌株携带一无自身转运功能的章鱼碱型Ti质粒pAL4404,此质粒含有vir基因(vir基因是T-DNA插入植物基因组必需的元件,pAL4404质粒自身的T-DNA转移功能被破坏,但可以帮助转入的双元载体T-DNA顺利转移)。pAL4404型Ti质粒含有筛选标签:Strep,赋予LBA4404菌株链霉素抗性,适用于菸草、番茄、烟草等植物的转基因操作。
产品用途:根瘤农杆菌菌株
原核抗性:Rif+、Str+
基因型: Ach5 (rifR) Ti pAL4404 (strepR) Octopine
培养基: LB培养基
培养条件: 28-30℃,有氧
产品规格:200μL 甘油菌
菌株扩增: 取100-200μl甘油菌,接种至3-5ml新鲜LB培养基(Rif+、Str+双抗性)中,28-30°C过夜摇菌即可。也可以先用甘油菌划板,然后挑单克隆,再过夜摇菌。
The LBA4404 strain has an Ach5-type background, with a screening marker—the rifampicin resistance gene Rif—in its nuclear genome. To facilitate transformation operations, this strain carries an octopine-type Ti plasmid pAL4404 that lacks self-transport functionality. This plasmid contains vir genes (which are essential components for the insertion of T-DNA into the plant genome; although the T-DNA transfer function of the pAL4404 plasmid itself is disrupted, it can assist in the smooth transfer of T-DNA from the introduced binary vector). The pAL4404-type Ti plasmid contains a screening marker: Strep, which endows the LBA4404 strain with streptomycin resistance and is suitable for transgenic operations in plants such as tobacco, tomato, etc.
Product Usage: Agrobacterium tumefaciens strain
Prokaryotic Resistance: Rif+、Str+
Genotype: Ach5 (rifR) Ti pAL4404 (strepR) Octopine
Culture Medium: LB Medium
Culture Conditions: 28–30°C, aerobic
Product Specification: 200 μL Glycerol Stock
Strain Amplification: Take 100–200 μL of the glycerol stock, inoculate it into 3–5 mL of fresh LB medium (with Rif+ and Str+ double resistance), and incubate with shaking overnight at 28–30°C. Alternatively, you can first streak the glycerol stock on an agar plate, then pick a single colony, and incubate with shaking overnight.
