D-Tryptophan is used for human embryonic kidney cell (HEK-293, ATCC: CRL-1573) culture. The product is a sweetener used to study the release of incretins from enteroendocrine cells triggered by sugar but not by sweeteners.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
D-Tryptophan is used for human embryonic kidney cell (HEK-293, ATCC: CRL-1573) culture. The product is a sweetener used to study the release of incretins from enteroendocrine cells triggered by sugar but not by sweeteners.
Solubility
Soluble in 0.5M hydrochloric acid (50 mg/ml), water (11 mg/ml at 20°C), hot alcohol, and dimethyl sulfoxide. Insoluble in chloroform.
