クロラムフェニコール耐性遺伝子を有するトランスフォーム細胞の選択薬として使用されます。細胞培養用途において10 ml/Lでの使用が推奨されます。
Biochem/physiol Actions
作用機序:クロラムフェニコールは、50Sリボソームサブユニットに結合してアミノアシルtRNAのリボソームへの付着を防ぐことでペプチジルトランスフェラーゼステップを遮断することにより細菌のタンパク質合成を阻害します。また、ミトコンドリアと葉緑体のタンパク質合成およびリボソームの(p)ppGpp生成を阻害して、rRNA転写を抑制します。
耐性機序:クロラムフェニコールアセチルトランスフェラーゼを使用することで、本製品はアセチル化され、不活性化されます。
抗菌スペクトル:グラム陽性菌およびグラム陰性菌に対して幅広いスペクトルを持つ抗生物質であり、主に眼科や獣医学的用途で使用されます。

Disclaimer
Stock solutions should be stored at 2-8°C and are stable at 37°C for 5 days. Aqueous solutions are neutral and stable over a wide pH range, with 50% hydrolysis occurring after 290 days. Use of a borax buffered solution reduces this number to 14%. Solutions should be protected from light as photochemical decomposition results in a yellowing of the solution. Heating aqueous solutions at 115°C for 30 minutes results in a 10% loss of chloramphenicol.
General description
Chemical structure: phenicole
Preparation Note
Stock solutions can be prepared directly in the vial at any recommended concentration. A solution at 50 mg/mL in ethanol yields a clear, very faint, yellow solution. Degradation of chloramphenicol in aqueous solution is catalyzed by general acids and bases. This rate of degradation is independent of the ionic strength and pH.

Proliferating cells require coordinated gene expression between the nucleus and mitochondria in order to divide, ensuring sufficient organelle number in daughter cells [1]. However, the machinery and mechanisms whereby proliferating cells monitor mitochondria and coordinate organelle biosynthesis remain poorly understood.

Blood transfusions are critically important in many medical procedures, but the presence of antigens on red blood cells (RBCs, erythrocytes) means that careful blood-typing must be carried out prior to transfusion to avoid adverse and sometimes fatal reactions following transfusion.

Trichosporon spp. have recently emerged as significant human pathogens. Identification of these species is important, both for epidemiological purposes and for therapeutic management, but conventional identification based on biochemical traits is hindered by the lack of updates to the species

Clostridium botulinum produces heat-resistant endospores that may germinate and outgrow into neurotoxic cultures in foods. Sporulation is regulated by the transcription factor Spo0A and the alternative sigma factors SigF, SigE, SigG, and SigK in most spore formers studied to date.
