General description

Pyridoxine (vitamin B6) is a form of vitamin B6. Other forms include the aldehyde pyridoxal and the amide pyridoxamine. It is an important cofactor for metabolism.[1]
Vitamin B group are water-soluble and exists in six forms which includes the pyridoxal, pyridoxine, pyridoxamine, pyridoxamine 5′-phospate, pyridoxine 5′-phosphate and pyridoxal 5′-phosphate. Vitamin B6 is distributed in nuts, whole grains and animal meat.

Application

Pyridoxine has been used as a component of:
  • artificial diet for sugarcane aphid pest
  • modified Strullu and Romand (MSR) medium for carrot root organ culture
  • Luria broth for E coli cultures

Pyridoxine is used in cell culture and other applications as a precursor to pyridoxal phosphate. It has been used as a standard in RP-HPLC (reversed phase high performance liquid chromatography) method. Pyridoxine has been used as a diet supplement to study lipid profile in rats.

Biochem/physiol Actions

Pyridoxine plays a key role in cell maintenance and amino acid metabolism. Deficiency of vitamin B6 leads to anemia especially in pregnant women and seizures in newborns. It serves as cofactor for heme biosynthesis during δ-amino levulinic acid formation, γ-aminobutyric acid (GABA) transaminase and glutamic acid decarboxylase. Vitamin B6 also helps in reactive oxygen species (ROS) scavenging and helps plants in overcoming the abiotic and biotic stress.

Questions

1–2 of 2 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  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
