Ornithine

Ornithine is an amino acid which is not coded for by DNA. It is one of the products of the action of arginase on L-arginine which leads to production of urea. Ornithine is a key component in urea cycle, which allows for the disposal of excess nitrogen. Another name: (+)-(5)-2,5-diaminovaleric acid

Synthetic ornithine conjugated to BSA

store lyophilized antibodies at  4°C; after reconstitution stode at -20°C. This aliquote is stable for at least 2 years. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
