ブラストサイジンSは、ストレプトミセスグリセオクロモ遺伝子から単離されたヌクレオチド抗生物質です。これは細菌や真核生物におけるタンパク質合成の強力な阻害剤であり、真菌類、線虫、腫瘍細胞に対しても有効です。ブラストサイジンSは、放出因子によって誘発されるペプチジル-tRNAの加水分解を阻害することで作用し、ペプチド結合形成を阻害します。哺乳類細胞と細菌細胞の両方で選択試薬として使用されます詳細を見る

ブラストサイジンSは、ストレプトミセスグリセオクロモ遺伝子から単離されたヌクレオチド抗生物質です。これは細菌や真核生物におけるタンパク質合成の強力な阻害剤であり、真菌類、線虫、腫瘍細胞に対しても有効です。ブラストサイジンSは、放出因子によって誘発されるペプチジル-tRNAの加水分解を阻害することで作用し、ペプチド結合形成を阻害します。哺乳類細胞と細菌細胞の両方で選択試薬として使用されます。推奨される使用濃度は、細胞株に応じて1~30 µg/mL、細菌の選択には25–100 µg/mLです。細胞死は急速に起こり、ブラスティチジン耐性の安定した哺乳類細胞株は1週間未満で生成できます。

ブラストサイジンSに対する耐性は、セレウス菌K55-Sおよびアスペルギルステルレウスからそれぞれ分離されたBSRおよびBSDによりもたらされます。BSR耐性遺伝子はブラストサイジンSデアミナーゼをエンコードします。これはブラストサイジンSのdeaminohydroxyblasticidin Sへの変換を触媒します。Deaminohydroxyblasticidin Sは生物学的に不活性なブラストサイジンSの誘導体であり、原核生物と真核生物のいずれのリボソームにも作用または阻害しません。また、BSD耐性遺伝子はブラストサイジンSデアミナーゼをエンコードし、これはBSRデアミナーゼと同様の反応を触媒します。細菌の選択を目的とした場合、LB培地の塩含有量は低く(<90 mM)、pHは7.0を超えないようにして、ブラストサイジンSの活性を維持する必要があります。耐性のない細胞を死滅させるためにもっとも効率の低いブラストサイジンS濃度を決定するために、殺菌曲線を推奨します。

よくあるご質問(FAQ)

Which of your antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for stable selection in mammalian cells?

All of our antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for making multiple stable cell lines. However, kill curves will need to be performed for each combination of antibiotics since sensitivity to a given antibiotic tends to increase when combined with other antibiotics.

What are the recommended concentrations of antibiotics to use for selection in prokaryotes and eukaryotes?

For best results, optimal concentrations for selection should be determined empirically in each unique experiment through dose response curves. However, to get a general idea of concentrations that have worked for individual cell types, please click on the following url: http://www.thermofisher.com/us/en/home/life-science/cell-culture/transfection/selection.html or type in “Selection Antibiotics” into our main search on www.thermofisher.com.

What is the mode of action on the following antibiotics: Blasticidin, Geneticin (G418), Hygromycin, and Zeocin?

Blasticidin: Nucleoside Inhibits protein synthesis in prokaryotic and eukaryotic cells by interfering with peptidyl transfer reaction of protein synthesis, causing early termination of translation.

Geneticin (G418): Aminoglycoside Blocks protein synthesis in mammalian cells by interfering with ribosomal function.

Hygromycin: Aminocyclitol Inhibits protein synthesis by disrupting translocation and promoting mistranslation.

Zeocin: Intercalates with DNA and cleaves it.

What is the optimal pH of low salt LB for LB + blasticidin plates?

We recommend a pH of 7 or less and half the normal amount of NaCl in your LB media or plates.

See the following paper for details on optimal conditions: Yamaguchi et al (1965) Inhibition of Protein Synthesis by Blasticidin S. Journal of Biochemistry (Tokyo) Volume 57: pp 667-677.

How long can Blasticidin be stored at 4 degrees C after thawing? Does the unused portion have to be discarded after thawing?

Blasticidin is stable for 6 months when stored at 4 degrees C. Discard remaining material after this time.

'Functional genomics approaches can overcome limitations-such as the lack of identification of robust targets and poor clinical efficacy-that hamper cancer drug development. Here we performed genome-scale CRISPR-Cas9 screens in 324 human cancer cell lines from 30 cancer types and developed a data-driven framework to prioritize candidates for cancer therapeutics.

Kinetochores act as hubs for multiple activities during cell division, including microtubule interactions and spindle checkpoint signaling. Each kinetochore can act autonomously, and activities change rapidly as proteins are recruited to, or removed from, kinetochores. Understanding this dynamic system requires tools that can manipulate kinetochores on biologically relevant temporal and ... More
