AdipoGen X-Gal (250 mg)
X-Gal (250 mg), Adipogen Life Sciences. Chemical. CAS: 7240-90-6. Formula: C14H15BrClNO6. MW: 408.6. Molecular biology reagent. Chromogenic substrate for beta-galactosidase. Used in gene cloning together with IPTG (Prod. No. AG-CC1-0002) to indicate whether a cell expresses the beta-galactosidase enzyme, which is encoded by the lacZ gene, in a technique called blue/white screening. Distinguishes between recombinant and non-recombinant plasmids carrying the beta-galactosidase gene. Used in two-hybrid analysis. X-Gal is used to determine E. coli and coliform content in drinking water samples.
Medchemexpress LLC Luc Yellow CH dilithium | 67769-47-5 | 99.7% | 100 MG
Luc Yellow CH dilithium is a high-intensity fluorescent probe containing free hydrazyl groups that can react with fatty aldehydes at room temperature.

Medchemexpress LLC Isrib (trans-isomer) | 1597403-47-8 | 99.49% | 451.34 | 50 MG
ISRIB (trans-isomer) is a potent inhibitor of PERK with an IC50 of 5 nM. It effectively reverses the effects of eIF2α phosphorylation and reduces the viability of cells subjected to PERK-activation by chronic endoplasmic reticulum stress. This trans-isomer is 100-fold more potent than cis-ISRIB, demonstrating stereospecific interaction with its cellular target.
- Potently reverses eIF2α phosphorylation (IC50=5 nM)
- Blocks eIF2α phosphorylation-induced stress granule (SG) formation
- Increases long-term memory in rodents
- Readily crosses the blood-brain barrier
