Clear solution
5% DMSO 95% Corn oil
0.625mg/ml Taking the 1 mL working solution as an example, add 50 μL of 12.5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 VH298 is a potent VHL (Von Hippel-Lindau, the E3 ligase) inhibitor that stabilizes HIF-α. VH298 blocks the VHL:HIF-α interaction with Kd of 90 nM in isothermal titration calorimetry (ITC) and 80 nM in a competitive fluorescence polarization assay. VH-298 can be used in PROTAC technology.
in vitro

VH298 can activate the HIF-1 signalling pathway by stabilizing both forms of HIF-1α in vitro. VH298 promotes rFb variability, migration, and synthesis of collagen and regulatory cell factors. VH298 improves the angiogenesis of hUVEC.[2]

反応時間 48 h
実験の流れ

The rFb are trypsinised and placed in flat-bottomed 96-well plates at an initial density of 5000 cells per well. After 24 h of incubation, the medium is changed to VH298-containing medium at different dosages (0 μM, 10 μM, 30 μM, 100 μM, and 200 μM). rFb are incubated at 37°C for 48 h. The proliferation is determined by the Cell Counting Kit-8 (CCK-8) assay. After incubation, rFb are treated with the CCK-8 solution at a final concentration of 10% for 2 h at 37°C, followed by measurement of absorbance at 450nm using a microplate reader.
