Application

L-Ornithine monohydrochloride has been used to study the blocking effect of L-ornithine on the transport system that carries L-arginine for the overproduction of nitric oxide during lipopolysaccharide induced endotoxemia in rat model.[1] It has also been used in decarboxylation test of amino acids.[2]

Biochem/physiol Actions

L-Ornithine is a product of arginase degradation and plays an important role in ammonia metabolism via the urea cycle. In mammals, ornithine serves as a precursor for polyamines and proline biosynthesis. Spermine synthesized from ornithine, is an abundant polyamine observed in tumors such as breast carcinomas.[3] Administration of L-ornithine is known to improve subjective index of sleep quality. L-ornithine reduces the cortisol/DHEA-S (dehydroepiandrosterone) ratio, that is associated with stress. In mice, L-ornithine is found to affect the levels of plasma growth hormone, corticosterone and melatonin levels in mice.[4]

Proline-rich antimicrobial peptides (PrAMPs) from insects and mammals have recently been evaluated for their pharmaceutical potential in treating systemic bacterial infections. Besides the native peptides, several shortened, modified, or even artificial sequences were highly effective in different murine infection models.

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.
