Nicotinamide, 100 g

Nicotinamide (also called niacinamide or vitamin B3) from STEMCELL Technologies is a research-grade reagent supplied as a 100 g powder for cell culture and biochemistry workflows. The compound acts as a direct precursor to nicotinamide adenine dinucleotide (NAD⁺), supporting cellular energy metabolism and redox balance in vitro. In stem cell research it is routinely included in reprogramming media and differentiation cocktails, where it has been reported to improve the efficiency of induced pluripotent stem cell generation and to help maintain neural and organoid cultures over extended passaging. The crystalline solid dissolves readily in water, allowing convenient preparation of stock solutions at typical working concentrations of 1–10 mM for supplementation of basal media such as DMEM or RPMI.

Store the dry powder at room temperature, protected from light and moisture in a tightly sealed bottle, to preserve chemical stability across repeated aliquots. Researchers studying NAD⁺ metabolism, sirtuin signaling, PARP activity, or oxidative stress pathways will find this bulk format practical for routine benchtop use, and the reagent is suitable for cell culture, molecular biology assays, and metabolic studies where a defined source of vitamin B3 is required.
