General description
コレラ毒素とそのAサブユニットは、アデニル酸シクラーゼに影響を及ぼすため、シグナル伝達機構の研究に広く用いられています。さらに、コレラ毒素は、インターロイキン-12の産生を阻害することによりBリンパ球およびヘルパーT細胞2型応答を刺激することによってアジュバントとして作用します。非毒性Bサブユニット(CTB)は、ガングリオシドGM1に結合することにより細胞に付着するため、神経学的研究におけるミクログリア細胞の有用な標識となっています。また、免疫組織化学的方法を用いた軸索輸送研究の優れたトレーサーであることもわかっています。

Can I dilute the stock solution further with water 1:100 to get 10ng/ml ? if yes how to store it ?
1 回答-
Dilution of the cholera toxin to 10 ng/mL in water is possible. Storage is recommended at 2-8 °C to avoid freezing, as stability in solution at -20 °C has not been determined.

Hey, Can this product be reconstituted to a solution and administered to mice for systemic upregulation of immune cells?
1 回答-
This product has not been tested for use in animal models, however, the preparation does contain sodium azide as a preservative. Azide is reported to have an LD50 of 19 mg/kg in mouse by I.V. route. This is not a sterile preparation, solutions would require filter sterilization prior to in vitro or in vivo use. Please see the link below to review the product datasheet:
