Product Information
| Description: | N-Carbamoyl-DL-aspartic acid (USA) is a pyrimidine biosynthesis intermediate that can be taken up by Saccharomyces cerevisiae when proline is the only nitrogen source, but USA uptake is inhibited when ammonium sulfate or glutamate is the nitrogen source. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
