Cellular Effect

Cell Line	Type	Value	Description	References
HEK293	IC₅₀	10 μM Compound: 7, SK1-I	Competitive inhibition of V5-His-tagged human SphK2 expressed in HEK293 cells assessed as S1P production using sphingosine and [gamma-32P]ATP as substrate by thin layer chromatography Competitive inhibition of V5-His-tagged human SphK2 expressed in HEK293 cells assessed as S1P production using sphingosine and [gamma-32P]ATP as substrate by thin layer chromatography	[PMID: 24471412]

In Vitro

SK1-I (0-10 μM; 24 hours) attenuates cancer cell growth and survival in a TP53-dependent manner in HCT116 cells and HCT116 cells bearing TP53 null cancer^[2].
SK1-I (0-20 μM; 12 hours) induces more CASP3 cleavage in HCT116 cells, compared to HCT116 cells lacking TP53, leading to a hallmark of apoptosis^[2].

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.
