Applications & Customer's Feedback of Paclitaxel (Taxol):

  • Paclitaxel was purchased from Selleck.Data from RSC Adv 2011.June.

    Microscope image (406) magnification of U937 cells after exposure to SM-TNs. a) Untreated U937 cells. b) U937 cells treated with 200 nm, and 35 nm ODS empty shells. c) U937 cells treated with microcrystalline (free) Taxol prepared by sonicating Taxol in 20%H3PO4/0.8% SDS solution. d) U937 cells treated with 200 nm SM-TN. A SM-TN is seen in the middle of the picture. e) U937 cells treated with 35 nm SMTN.The nanowires are too small to see at this magnification, but their effect on the cells is clearly visible. Scale bar = 10 mm.

Biological Activity of Paclitaxel (Taxol):

Paclitaxel is a microtubule polymer stabilizer with an IC50 of 0.1 pM for human endothelial cells. It selectively inhibits the proliferation of human endothelial cells (ECs) at ultra low concentrations (0.1-100 pM), while it inhibits non-endothelial type human cells at 10(4) - to 10(5) -fold higher concentrations, with IC50 = 1-10 nM. The selectivity of paclitaxel inhibition of cell proliferation is also species specific, as mouse ECs are not sensitive to paclitaxel at ultra low concentrations. They are inhibited by higher concentrations of paclitaxel with IC50 = 1-10 nM. Inhibition of human ECs by paclitaxel at ultra low concentrations does not affect the cellular microtubule structure. Paclitaxel blocks cells in G2-M, and this may result in a schedule-dependent effect on paclitaxel cytotoxicity. [1][2][3]

Customer's Feedback
Arnaud AUTRET, Trinity College
"I would like to confirm you that everything is perfectly fine with ABT and Obatoclax we got from your company. We confirmed their activity in vitro. We notably observed their impact in an apoptotic model and results are similar to those which have been published."

Dongfeng Chen, The Rausing Lab
"Your product U0126(Cat.NO S1102) works well in our experiments. I hope I can get more excellent products from your company in future."

Dr. Alexandra Segref, CECAD Cologne,Germay
"I am very satisfied with your product and costumer service. Bortezomib works very well in our assay, it is comparably cheaper than other inhibitors that we tested is more reliable for our assays. We see a great effect by using 10nM concentration."

R.B. Cambridge
"I have used the chemical that I bought from you(Selleck,PTC-124) and it worked well.So we will eventually be ordering more."

Zhenghe John Wang Assistant Professor, Case Western Reserve University
"We have purchased LBH-589, Saha and MS-275 from you and they all worked well."

Jenny Sun
"We used the LBH-589 in our experiments. The compound is easy to use with excellent reproducibility."

Yu Wang, Harvard University
"The GDC0449 compound worked very well. The results in my hands are equally good as what's been published. Thanks for this great resource for our research."

Philip Seeman, Toronto University
"Your LY404039 compound was well synthesized, its complicated stereochemical structure confirmed by NMR spectroscopy, and was biologically excellent in acting on brain dopamine receptors."

Dung-Fang Lee
"Based on our preliminary data, I found MLN8237 and VX-680 have good effects in inhibiting Aurka-maintaining ESC self-renewal in mouse ES cells."
