应用

(+)-Abscisic acid has been used:
  • as a supplement for the germination of Arabidopsis thaliana seeds
  • as a component of buffered nodulation medium to check its effects on lateral root density (LRD) in leguminous and non-leguminous plants
  • as a standard to study its effects on root meristem defects in Medicago truncatula latd mutant

生化/生理作用

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. What solvents can be used with Product A4906, (+)-Abscisic acid?

    Abscisic acid, Product No. A4906, is soluble in ethanol (10 mg/mL), yielding a clear, colorless solution. For plant cell culture, it can be solubilized in a small amount of 1 N NaOH and diluted with water or medium.

  5. How is Product A4906, (+)-Abscisic acid, prepared?

    This product is synthetic. This isomer is isolated from the racemic mixture.

  6. How should Product A4906, (+)-Abscisic acid solutions be stored?

    A solution of (+)-Abscisic acid should be stored in single use aliquots at -20°C.

  7. What concentration of Product A4906, (+)-Abscisic acid, is used in plant cell culture?

    (+)-Abscisic acid is used at 0.1 to 10 mg/L for plant cell culture.
