Delivering Precise Results for Anyone's Streptomycin Sulfate (STP) Analysis Needs

CD BioGlyco is dedicated to research in all aspects of glycobiology. Since glycoconjugates are an important source of certain pharmaceuticals, we provide comprehensive Pharmaceutical Analysis Services to our clients. One of them is STP, an aminoglycoside antibiotic pharmaceutical that has a powerful antibacterial effect against Mycobacterium tuberculosis. To explore its physiological functions more deeply, we provide high-quality STP analysis services. The analysis services we provide include but are not limited to, the following.

• Identification of STP
  Colorimetric assay: Dissolve the sample to be identified with sodium hydroxide solution and alcohol solution of hydroxyquinoline, then add a small amount of sodium hypobromite solution and observe the color of the solution to be tested. If the solution shows orange-red color it means that the sample to be tested is STP.
• Content
  Liquid chromatography (LC): We separate STP using acetonitrile and water as mobile phase and sodium phosphate solution as buffer. Then, the content is calculated based on the area of the peak of STP. In addition, we also provide ultraviolet spectrophotometry (UV), barium sulfate precipitation method, and bioefficiency method for clients to choose from.
• Sulfate content
  STP samples are dissolved in water and titrated using barium chloride solution and sodium ethylenediaminetetraacetate solution. The termination time of the titration is determined according to the color change of the solution during the titration. Finally, we will calculate the content of sulfate in STP based on the amount of barium chloride solution used.
• Acid-base
  We dissolve and dilute the STP to be tested with water, followed by testing its pH using a pH meter. The pH of STP should be between 4.5 and 7.0.
• Loss on drying
  The weight loss is measured under reduced pressure and at elevated temperatures. In general, the weight loss of streptomycin sulfate should not exceed 6.0%.
• Toxicity
  We accurately weigh a small amount of STP to which we add sodium chloride solution to make a solution. In vivo experiments with animals are then carried out, where the drug is administered intravenously and the survival of the animals is observed.

In addition, sterile powder of STP can be made into a preparation (STP for injection) for use. Identification and analysis of STP for injection is usually similar to that of STP. Therefore, we offer the identification and analysis of STP for injection in the manner described above.
