The effects that combining SBPE to chemotherapy drugs Gemcitabine and Paclitaxel have on cancer cell viability.

<p>(a) A549 tumor cell viability analysis after the administration of Gemcitabine. After 1 μM, 5 μM, 10 μM, 50 μM, and 100 μM of Gemcitabine was administered for 24 and 48 hours, the MTS reagent was used to detect their activities. Secondly, after 6 hours of treatment with 10 mg/mL of SBPE; Gemcitabine was added for 24 hours (b), 48 hours (c) and 72 hours (d). (e) A549 tumor cell viability analysis after treatment with 1 μM, 5 μM, 10 μM, 50 μM, and 100 μM of Paclitaxel and incubated for 24 and 48 hours. The MTS reagent was used to detect their activities. Secondly, after 6 hours of treatment with 10 mg/mL of SBPE; Paclitaxel treatment was added for 24 hours (f), 48 hours (g) and 72 hours (h).
