Efficacy and Accuracy for Group A Meningococcal Polysaccharide Vaccine

Whether you are looking for Pharmaceutical Analysis, Biological Evaluation, or Pharmaceutical Excipient Analysis, CD BioGlyco has the best-in-class analytical technology and professional operators to meet all the needs of our clients in Pharmaceutical and Biological Analysis. Meningococcal polysaccharide vaccine is a classical vaccine containing the podocarboxylic polysaccharide antigen. It is commonly used to prevent epidemic meningitis caused by Neisseria meningitides. Our team provides high-quality evaluation for group A and C meningococcal polysaccharide vaccine, group A and group C meningococcal conjugate vaccine, and group ACYW135 meningococcal polysaccharide vaccine.

• Bulk testing
  • Identification
    CD BioGlyco observes the precipitates formed by the samples to be tested with antibodies against group A Neisseria meningitidis by double immunodiffusion assay.
  • Basic testing
    • Total solid
    • O-Acetyl content
    • Phenol residue

    • Protein content
    • Phosphate content
    • Sterility test

    • Nucleic acid content
    • Polysaccharide molecular size distribution
    • Bacterial endotoxin test
• Final bulk testing
  • Sterility testing of semi-finished vaccines is very essential and we provide reliable sterility testing services to clients.
• Final product testing
  • CD BioGlyco provides accurate and high-quality basic testing including load discrepancy tests, moisture determination, polysaccharide content determination, polysaccharide molecular size distribution determination, and abnormal toxicity tests.
  • CD BioGlyco provides osmotic concentration and pyrogen testing services. Our researchers use measurements of the freezing point drop of a solution to indirectly determine its osmotic concentration. For the pyrogen testing, we inject a certain dose of vaccine, intravenously, into rabbits, and observe the rabbits' body temperature rise over a specified period to determine the limit of pyrogens contained in the vaccine.
• Diluent determination
  • CD BioGlyco provides high-quality vaccine diluent assay services including visible foreign body inspection, pH measurement, sterility test, and bacterial endotoxin assay services.

Applications

• Our evaluation service further facilitates polysaccharide vaccine development and characterization.
• Assessed group A meningococcal polysaccharide vaccines provide better prevention and control of infectious diseases such as influenza and pneumonia.
• Detection of immune response to group A meningococcal polysaccharide vaccine facilitates the study of transcriptomes of vaccine candidate genes.

Advantages of Us

• Our specialized analysts offer not only final vaccine assays but also bulk and final bulk assays.
• Our researchers strictly adhere to sterility conditions. The environment is tested before the inspection to ensure accurate data.
• For all animal-related tests, we offer a one-stop evaluation service from animal culture, injection planning, long-term observation to data reporting.

Based on advanced analytical systems, CD BioGlyco provides high-quality pharmaceutical and biological analysis services. Our efficient and highly satisfying services have been recognized by our clients all over the world. Don't hesitate to contact us whenever you need assistance.
