설명

일반 설명

Nicotinamide adenine dinucleotide (NAD) is a cofactor containing an adenylic acid and a nicotinamide-5′-ribonucleotide group linked together by a pyrophosphate moiety. It is ubiquitously found. In NAD⁺ complexes, the enzyme-cofactor interactions are highly conserved.

애플리케이션

NAD has been used in boiled-blood agar plate as a supplement for the growth of Actinobacillus pleuropneumoniae colony.

생화학적/생리학적 작용

Nicotinamide adenine dinucleotide (NAD) acts as an electron carrier and significantly participates in enzyme-catalyzed oxido-reduction processes and many genetic processes. NAD cycles between the oxidized (NAD⁺) and reduced (NADH) forms to maintain a redox balance necessary for continued cell growth. This cofactor is also involved in microbial catabolism. β-NAD acts as a substrate for various enzymes in several cellular processes.

제조 메모

Storage conditions (working solution): An aqueous solution in a concentration of 10 mg/ml (pH 2.5 to 3) maintains > 99% of its NAD content after 8 weeks of storage at 2 to 8 °C.
The stability of an aqueous solution in a concentration of 40 mg/ml is not expected to differ from that of a solution in a concentration of 10 mg/ml.

An aqueous solution in a concentration of 50 mg/ml (pH 2.0) maintains 97% of its NAD content after 2 days, 94% after 6 days and 91% after 10 days of storage at 2 to 8 °C and about 83% after 10 days of storage at 33 °C.

An aqueous solution in a concentration of 1.38 mg/ml shows a decrease of NAD content of 4% after 8 weeks of storage at 2 to 8 °C, stored at -15 to -25 °C the stability is expected to be > 6 months. A solution of NAD in triethanolamine buffer (pH 5.0) maintians 90% of its NAD content after
10 days of storage at 2 to 8 °C and 80% after 10 days of storage at 33 °C.
