Application

This analytical standard was used as follows:
  • Identification and quantification of amino acids in the proteins extracted from two cricket species— A. domesticus and G. bimaculatus, using an amino acid analyzer based on ion-exchange chromatography with Ninhydrin for post-column derivatization
  • Free amino acid analysis of plasma samples using an amino acid analyzer to evaluate the effect of induced changes in testosterone levels on protein turnover for a group of 30 healthy human males
  • Plasma analysis for amino acids using ultra high-performance liquid chromatography coupled to a single quadrupole mass detector (QDA)
  • Determination of 26 clinically essential amino acids in plasma samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS) following amino acid amine derivatization
  • To spike samples in the liquid chromatography-mass spectrometry (LC-MS) method-based determination of 39 amino acids and related compounds in plasma and urine samples using a mixed-mode (MM) column

Other Notes

Amino acids listed are 2.5 μmoles per mL except L-cystine at 1.25 μmoles per ml.

Questions

1–3 of 3 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
