IETDC

IETDC is a caspase 8-responsive fluorescent probe. IETDC is cleaved by activated caspase 8 to release D-cysteine, which then reacts with 6-hydroxy-2-cyanobenzothiazole (HCBT) to form firefly luciferin in situ. IETDC must be used in conjunction with PCL-2 (HY-D3168) to detect the co-existence of hydrogen peroxide and caspase 8. IETDC is applicable to studies related to acute inflammation.

In Vitro

IETDC (5 μM; 60 min) is selectively cleaved by recombinant caspase 8 but not caspase 3 or caspase 9 to release D-cysteine, which forms luciferin with HCBT to produce a ca. 27-fold increase in bioluminescent signal, and this response is fully inhibited by a pan-caspase inhibitor^[1].
IETDC (10 μM; 60 min) acts as part of an AND-type molecular logic gate, producing an ca. 18-fold increase in bioluminescent signal only when combined with PCL-2, hydrogen peroxide, and active caspase 8, with signal blocked by inhibition of either hydrogen peroxide-mediated PCL-2 cleavage or caspase 8-mediated IETDC cleavage^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

IETDC (0.05 μmol; i.p.; single dose), co-administered with HCBT, produces an 18-fold bioluminescent signal increase in female FVB-luc+ mice with lipopolysaccharide-induced acute inflammation, which is 34% attenuated by pre-treatment with a pan-caspase inhibitor^[1].
IETDC (0.05 μmol; i.p.; single dose), co-administered with PCL-2, produces a 2.7-fold bioluminescent signal increase in female FVB-luc+ mice with LPS (HY-D1056)-induced acute inflammation, which is 30% attenuated by co-treatment with ascorbic acid and a pan-caspase inhibitor^[1].

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.
