General description

Kanamycin Sulfate is a broad spectrum aminoglycoside-antibiotic purified from the bacterium Streptomyces kanamyceticus. Kanamycin Sulfate is a selection agent for cells in culture media and acts by binding to the 30S subunit of the bacterial ribosome which inhibits protein synthesis in susceptible bacteria.

Application

Kanamycin sulfate is used as an additive in culture media for the isolation of group D streptococci on Kanamycin Esculin Azide Agar and for selection of transformed plant cells containing the neomycin phosphotransferase on a kanamycin-medium. Kanamycin sulfate can also be used as a selection agent for cells transformed with kanamycin B resistance gene. It is recommended for use in cell culture applications at 100 μg/mL. Kanamycin sulfate from Streptomyces kanamyceticus has been used: in the research of cell type-specific expression of genes[1][2]

Biochem/physiol Actions

Mode of Action: The product acts by binding to the 70S ribosomal subunit, inhibiting translocation and eliciting miscoding.

Mode of Resistance:Aminoglycoside-modifying enzymes (including acetyltransferase, phosphotransferase, nucleotidyltransferase) can alter this antibiotic, preventing its interaction with ribosomes.

Antimicrobial spectrum: Kanamycin sulfate is effective against gram-negative and gram-postiive bacteria, and mycoplasma.

Features and Benefits

  • High quality antibiotic suitable for mulitple research applications
  • meets USP testing specifications

Preparation Note

Tightly closed. Dry. Keep in a well -ventilated place. Keep locked up or in an area accessible
Kanamycin sulfate is soluble in water at 50 mg/mL, yielding a clear solution. It is practically insoluble in alcohol, acetone, chloroform, ether and ethyl acetate. A 1% solution in water has a pH of 6.5 to 8.5. Sterile solutions can be prepared by a sterile filtration, through a .2μm filter.

Solutions are stable at 37°C for approximately 5 days. Aqueous stock solutions can be stored at 2-8°C for long term storage.

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
