Popis: USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.

Popis: ALAS-1 (EC 2.3.1.37) is a nuclear-encoded mitochondrial matrix enzymecatalyzing the condensation of glycine with succinyl-CoA to form delta-amino levulinate, CO2 and CoA. It regulates the first and rate-limiting step of heme biosynthetic pathway. It is one of the two isoforms of ALAS and is a pyridoxal-5 phosphate dependant housekeeping enzyme. It is ubiquitously expressed and is responsible of providing heme for cytochromes and other hemoproteins. ALAS1 in liver undergoes negative feedback regulation by heme. Transcription of ALAS1 gene is stimulated by cAMP and respiratory uncoupling whereas Phorbol esters and insulin repress ALAS1 gene expression. ALAS1 is suggested to be involved in reciprocal regulation of Heme biosynthesis and circadian clock suggesting a potential target for treatment of circadian disorders. ALAS1 gene expression is down regulated in Acute Liver failure resulting in altered heme metabolism and liver function.
