In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  15% Cremophor EL    85% Saline

    Solubility: 10 mg/mL (27.44 mM); Suspended solution; Need ultrasonic

  • Protocol 2

Exponentially growing cells are processed in lysis buffer (20 mM HEPES, pH 7.4, 1 mM EDTA, 5 mM MgCl2, 100 mM KCl) and incubated with increasing concentrations of 17-AAG or ganetespib for 30 min at 4°C, and incubated with biotin-GM linked to Dynabeads MyOne Streptavidin T1 magnetic beads for 1 h at 4°C. Beads are washed three times in lysis buffer and heated for 5 min at 95°C in SDS-PAGE sample buffer. Samples are resolved on 4-12% Bis-Tris gradient gel and Western blots are performed using an anti-HSP90 antibody.

Cells are grown in 96-well plates based on optimal growth rates determined empirically for each line. Twenty-four hours after plating, cells are treated with the indicated compounds or controls for 72 hours. AlamarBlue is added (10% v/v) to the cells, and the plates are incubated for 3 hours and, then, subjected to fluorescence detection. For the comparative viability/apoptosis assay, NCI-H1975 cells are treated with escalating concentrations of ganetespib for the indicated time periods and subjected to viability analysis via CellTiter Fluor and apoptosis via Caspase Glo 3/7.

Mice: NCI-H1975 or HCC827 cells are cultured as above and 0.5-1×107 cells are mixed with 50% RPMI 1640/50% Matrigel and subcutaneously injected into the flanks of SCID mice. For efficacy studies, animals with 100-200 mm3 tumors are then randomized into treatments groups of eight. Tumor volumes (V) are calculated by the equation V=0.5236×L×W×T (Length, width, and thickness). Animals are treated by intravenous bolus tail vein injection at 10 mL/kg with ganetespib formulated in 10/18 DRD (10% DMSO, 18% Cremophor RH 40, 3.6% dextrose and 68.4% water). As a measurement of in vivo efficacy, the relative size of treated and control tumors [(%T/C) value] is determined from the change in average tumor volumes of each drug-treated group relative to the vehicle-treated group, or itself in the case of tumor regression. Body weights are monitored daily. For biomarker studies, mice bearing NCI-H1975 xenografts are treated with either a single dose of vehicle or ganetespib, or with 5 daily doses of vehicle or ganetespib, in groups of 3 or 8, and harvested at various time points. Tumors are excised and flash frozen in liquid nitrogen for preparation of protein lysates or fixed in 10% neutral buffered formalin for immunohistochemistry.

  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
