Popis

General description

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards

Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

8-methoxypsoralen (8-MOP) plus ultraviolet A (UVA) irradiation induces monoadducts and interstrand cross-links in DNA and therefore can be used to study DNA repair and recombination mechanisms. Cultured normal human melanocytes treated with 8-methoxypsoralen and irradiated with ultraviolet A (UVA) formed 8-methoxypsoralen-phospholipid photoadducts that could be substituted for diacylglycerol to activate protein kinase C in a cell-free system. 8-MOP is an inactivator of purified reconstituted cytochrome P450. It also inhibits substance P-induced histamine release from substance P-activated rat peritoneal mast cells by suppressing the rise in [Ca²⁺].

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
