General description

Hermansson described the use of natural proteins immobilized onto a silica support for chiral separations in 1983 (1). Proteins contain a large number of chiral centers of one configuration, and many other sites that contribute to the general retention process. CHIRALPAK AGP has the broadest range of selectivity of all protein phases currently available. CHIRALPAK AGP phase uses α1-acid glycoprotein (AGP) as the chiral selector immobilized on spherical 5 μm silica particles. Bonded AGP is a very stable protein that tolerates pure organic solvents, elevated temperatures and pH values from 4 to 7. Operated in reversed-phase mode, CHIRALPAK AGP column separates enantiomers of an extremely broad range of drug substances, such as acids, amines and neutral compounds. The enantioselectivity and retention can easily be regulated by mobile phase pH and ionic strength, and the nature and concentration of the organic modifier.

Features:

  • Direct reversed phase resolution of chiral molecules
  • Stable with a variety of organic modifiers
  • Available in analytical and semi-preparative sizes

Application


  • Enantiomeric methadone quantitation on real post-mortem dried matrix spots samples: Comparison of liquid chromatography and supercritical fluid chromatography coupled to mass spectrometry.: This study explores the application of enantioselective liquid chromatography techniques, including the use of CHIRALPAK® AGP, for the quantitation of methadone enantiomers on dried matrix spots, contributing to forensic toxicology and analytical chemistry (Mueller et al., 2021).

  • Enantiomeric Separation of Dioxopromethazine and its Stereoselective Pharmacokinetics in Rats by HPLC-MS/MS.: This research demonstrates the utility of chiral stationary phases, such as CHIRALPAK® AGP, for separating enantiomers of pharmaceutical compounds, providing insights into stereoselective pharmacokinetics critical for drug development and clinical pharmacology (Lun et al., 2021).

  • Evaluation of R- (-) and S- (+) Clenbuterol enantiomers during a doping cycle or continuous ingestion of contaminated meat using chiral liquid chromatography by LC-TQ-MS.: This article details the application of chiral liquid chromatography, potentially involving CHIRALPAK® AGP columns, to distinguish between therapeutic use and contamination sources of clenbuterol, addressing challenges in sports doping analysis (Dolores et al., 2019).

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
