ISRACT-01

ISRACT-01 is an integrated stress response (ISR) activator. ISRACT-01 has a K_d of 557 nM for eIF2B^Δ-latch. ISRACT-01 cooperates with eIF2-P to inhibit guanine nucleotide exchange factor (GEF) activity by specifically binding to and stabilizing the inactive conformation (I-state) of eIF2B. ISRACT-01 can be used in studies related to amyotrophic lateral sclerosis.

eIF2BΔ-latch

557 nM (Kd)

In Vitro

ISRACT-01 (2.4 μM; 5 days) protects BJ fibroblasts treated with Tunicamycin (HY-A0098) from apoptosis^[1].
ISRACT-01 (2-10 μM; 30 min-3 h) inhibits polyribosome formation and promotes the accumulation of ATF4 protein expression in wild-type mouse fibroblasts^[1].
The K_d value for the binding of FAM-ISRACT-01 (2.5 nM; 30 min) to the eIF2B^Δ-latch decamer is 557 nM^[1].

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

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.
