Since there is an uncertain -R group in this product that contains three possibilities, the molecular weight can't be determined. To make a 10 mg/mL solution, the molecular weight is not needed. Simply weigh out the appropriate amount of the compound (e.g. 100 mg) and add it to the corresponding volume of solvent (e.g. 10 mL) to achieve a 10 mg/mL concentration. Please note this product is recommended for use at 50 mg/L.

Description générale
Gentamicin is an aminoglycoside complex produced by fermentation of Micromonospora purpurea or M. echinospora. It is used as the sulfate salt. There are three components, each consisting of five basic nitrogens and requiresing five equivalents of sulfuric acid per mole of gentamicin base.
This broad-spectrum antibiotic,[1] is widely used as an active pharmaceutical ingredient (API) with therapeutic potential against both Gram-positive and Gram-negative bacteria.[2]Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.

Application
Gentamicin Sulfate may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations[2][3] using different chromatography techniques. It is also used as a selection agent (gentamicin-resistance gene) in cell culture and molecular biology applications. This product is recommended for use at 50 mg/L.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Actions biochimiques/physiologiques
Mode d'action : La gentamicine provoque des erreurs de lecture au niveau des codons en se fixant sur la sous-unité ribosomale 30S, ce qui bloque la translocation du peptidyl-ARNt entre le site accepteur et le site donneur. L'effet bactéricide de la gentamicine sur Pseudomonas aeruginosa est dû à la fixation de la gentamicine sur la membrane extérieure, où elle déplace les cations naturels, déstabilise la membrane et forme des trous à la surface de la cellule.
Spectre antimicrobien : Inclut les bactéries à Gram négatif et à Gram positif, notamment les souches résistantes à la tétracycline, au chloramphénicol, à la kanamycine et à la colistine, en particulier les souches de Pseudomonas, Proteus, Staphylococcus et Streptococcus.

Attention
Sterile solutions should be stored at 2-8°C. Solutions have also been shown to be stable at room temperature and in boiling aqueous buffers of pH 2-142.

Hi, I would like to make a stock solution for antimicrobial susceptibility test. I would like to ask what is the molecular weight of this compound and how many grams of powder should I used to make a 10 mg/mL gentamicin solution? Thank you.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
