生物活性

Suc-Leu-Leu-Val-Tyr-AMC is a fluorogenic substrate.

体外研究
(In Vitro)

Suc-Leu-Leu-Val-Tyr-AMC (Suc-LLVY) is a membrane-permeable calpain-specific fluorogenic substrate, pteolytic hydrolysis of the peptidyl-7-amino bond liberates the highly fluorescent 7-amino-4-methylcoumarin (AMC) moiety[1]. The effect of TGF-β on hydrolysis of these substrates (e.g Suc-Leu-Leu-Val-Tyr-AMC) are assessed. Biliary epithelial H69 cells are incubated with 10, 1, 0.1, or 0 ng/mL TGF-β for 24 h. Substrate hydrolysis is then fluorometrically assessed in cytosolic extracts. Basal activity is 1.12, 8.33, and 14.52 nmol AMC/mg protein/min for suc-LLVY-AMC, z-LLE-AMC, and z-LLL-AMC hydrolysis, respectively[2].

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

Immunoprecipitation is carried out for the two sets of samples, using the same amount of protein. The 20 S and 26 S proteasome immunoprecipitates are washed with 50 mM Hepes/KOH (pH 7.5), and 50 mM Hepes/KOH (pH 7.5) containing 2 mMATP, respectively, prior to the determination of peptidase activity using 50 μM suc-Leu- Leu-Val-Tyr-AMC as substrate in these buffers[3].

生物活性

{Val1}-Exendin-3/4 is the first N-terminal 1-28 residues of Exendin-4 peptide.

体外研究
(In Vitro)

Exendin-4 is a pure GLP-1 receptor agonist. Exendin-4 peptide derivatives are structurally derived from Exendin-4 and may relates to dual GLP-1/glucagon receptor agonists. Their medical use, for example in the treatment of disorders of the metabolic syndrome, including diabetes and obesity, as well as for reduction of excess food intake. These dual GLP-1/glucagon receptor agonists show reduced activity on the GIP receptor to reduce the risk of hypoglycemia[1].
