Discussion above was valid for two color indicators, however, there are also indicators that have only one color - like phenolphthalein. 0.1 M strong monoprotic acid titrated with 0.1 M strong monoprotic base in the presence of the phenolphthalein. Note that while only color change area is marked on the plot, solution is colorless for lower pH and pink for higher pH.
Many different types of chemotherapy drugs are used to treat breast cancer. Common types of chemotherapy drug classes include: Anthracyclines include doxorubicin (Adriamycin) and epirubicin (Ellence). Anthracycline-based combination regimens are often used to treat early-stage breast cancer, as well as advanced cancer.
Tetracyclines (tetracycline, doxycycline, minocycline, oxtetracycline, ...) are antibiotics which inhibit the bacterial growth by stopping protein synthesis.They have been widely used for the past forty years as therapeutic agent in human and veterinary medicine but also as growth promotor in animal husbandry.everal tetracycline resistance determinants are currently used in molecular biology. The most encountered are the tetA genes of classes A (RP1, RP4 or Tn1721 derivatives), B (Tn10 derivatives) and C (pSC101 or pBR322 derivatives) encoding a tetracycline efflux system.
