HY-W014504

*DL-Kynurenine*	Endogenous Metabolite	Metabolic Disease
DL-Kynurenine is a key metabolite in the tryptophan metabolic pathway and can cross the blood-brain barrier. DL-Kynurenine has a bidirectional regulatory effect on neural excitability. DL-Kynurenine can enhance the convulsive and lethal effects caused by strychnine. DL-Kynurenine is the precursor of Kynurenic acid (HY-100806), which is an antagonist at the glycine site of NMDA receptors and can counteract excitatory toxins. DL-Kynurenine can be used for research on neurotoxicity .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
