VS 8 is shown to be a pro-oxidant molecule that enhances the ROS level in Hep G2 cells^[1].
VS 8 inhibits wound healing and migration of MCF-7 cancer cells^[1].
VS 8 downregulates human vascular endothelial growth factor (hVEGF) and hVEGFR-2 expression in HUVECs^[1].

Cell Proliferation Assay^[1]

Cell Line:

MCF-7, MDA-MB-231, Hep G2, and HUVECs cells
Concentration:

0.01, 0.1, 1, 10, 50, and 100 µM
Incubation Time:

24 h
Result:

Showed significantly potent anti-proliferative activity against all the selected cell lines in a dose-dependent manner, with IC₅₀ values of 953.30, 1413, 257.80, and 1954 nM against MCF-7, MDA-MB-231, Hep G2, and HUVECs cells.

Apoptosis Analysis^[1]

Cell Line:

MDA-MB-231, Hep G2, and HUVECs cells
Concentration:

1413, 257.80, and 1954 nM for MDA-MB-231, Hep G2, and HUVECs cells, respectively.
Incubation Time:

72 h for MDA-MB-231 cells; 24 h for Hep G2 and HUVECs cells
Result:

Resulted in high population of early apoptotic MDA-MB-231 cells (68.34 ± 0.18%). A significant increase in % apoptotic index (~86.66%) was observed in Hep G2 cells. The percentage of early apoptotic cells were found to be ~37.53% in HUVECs cells.

Cell Cycle Analysis^[1]

Cell Line:

CD44+ and CD133+ CSCs isolated from Hep G2 cells
Concentration:

257.80 nM
Incubation Time:

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
