BioVector® AD12345678(通常简称为 AD1-8)是一种专门用于研究 **ABC 转运蛋白(ATP结合盒转运蛋白)和多药耐药机制的酿酒酵母(Saccharomyces cerevisiae)**实验室工程菌株。

遗传背景与特性
该菌株的核心设计思路是通过基因工程手段敲除了酵母内源的主要 ABC 转运蛋白基因。这样可以消除背景外排干扰,使研究人员能够在一个“干净”的背景中表达并观察外源转运蛋白的功能。
  • 宿主物种: 酿酒酵母 (Saccharomyces cerevisiae)。

  • 基因型(敲除列表): 该菌株敲除了 8 个主要的转运蛋白基因:

    • yor1Δ

    • snq2Δ

    • pdr5Δ

    • pdr10Δ

    • pdr11Δ

    • ycf1Δ

    • pdr3Δ

    • pdr15Δ


主要应用与优势
  1. 高度敏感性: 由于缺失了上述基因,AD12345678 对多种异物和药物(如 罗丹明B、寡霉素、4-NQO)表现出极高的敏感性。

  2. 异源表达平台: 常被用作测试植物或人类 ABC 转运蛋白(如 AaABCG40CjMDR1)底物特异性和转运活性的首选平台。

  3. 生物化学分析: 广泛应用于 ATPase 活性测定和药物敏感性实验,用于表征如 Yor1p 等蛋白的生化特性。

BioVector®

AD12345678 (often referred to simply as AD1-8) is a specialized laboratory strain of Saccharomyces cerevisiae (yeast) engineered specifically for studying ABC (ATP-Binding Cassette) transporters and multidrug resistance.
Genetic Profile
The defining characteristic of this strain is the deletion of several major endogenous ABC transporter genes to eliminate background drug efflux activity. This allows researchers to express a single foreign or specific transporter and observe its function without interference from native yeast pumps.
  • Host Organism:Saccharomyces cerevisiae.

  • Genotype (Deletions): The strain lacks eight major transporters:

    • yor1Δ

    • snq2Δ

    • pdr5Δ

    • pdr10Δ

    • pdr11Δ

    • ycf1Δ

    • pdr3Δ

    • pdr15Δ.


Key Characteristics & Applications
  • Hypersensitivity: Due to these deletions, AD12345678 is highly sensitive to a wide range of xenobiotics and drugs that would normally be pumped out by the cell, such as rhodamine B, oligomycin, and 4-NQO.

  • Expression Platform: It is widely used as a "clean" background to test the substrate specificity and transport activity of plant or human ABC transporters, such as the Artemisia annuaAaABCG40 transporter or the CjMDR1 transporter.

  • Assay Utility: It is frequently used in ATPase activity assays and drug sensitivity tests to characterize the biochemical properties of overexpressed proteins like Yor1p.

Comparison to Related Strains
  • AD2345678: A closely related strain that retains the YOR1 gene, often used as a control for Yor1p-specific studies.
